**The systems to win at roulette**

The methods to win at roulette exist, even if the ones that really work are perhaps two or three and certainly today very difficult to apply in a casino.

I have already written another about winning roulette systems article which I invite you to read if you want to understand this topic better.

As you will read in the post ►systems to win at roulette that really work, among the few really successful roulette methods one very effective in the past was the one that planned to play at **biased roulette**.

It has often been theorized that no roulette wheel is mechanically perfect and therefore over time all of them can be subject to defects in certain sectors or certain boxes.

The history of roulette is full of anecdotes about players who discovered these flaws and successfully exploited them to achieve **huge winnings**.

Some of the most famous episodes are about a XNUMXth century English mechanic named **Joseph jagger**, which won in Monte Carlo the equivalent of about $ 250.000 of the time.

Two college students, **Al Hibbs** e **Roy Walford**, in the late 40s they won $ 25.000 at Casino Reno and almost became national celebrities.

Between 1986 and 1989, a well-known high roller player named **Billy walters** won over $ 4 million in Atlantic City!

These have been fantastic results and certainly worthy of the fame they have generated, and each of these ventures required considerable preparatory work.

The various teams of clockers spent weeks recording the results of spins on dozens of roulette wheels to find **physical defects**; qWhen a flaw was finally found, the player sat down at the table and bet on the biased numbers **24 hours on 24**, until a winning target was reached, or until the casino management stopped the game.

Since the end of the 80's casino operators have started to be very interested in the possible defects of roulette, before then most of the wheels had very high box separators, **fixed as individual components** and these certainly contributed a lot to generating the defects.

Between 1989 and 1991, most casinos changed the old roulettes, replacing them with new ones **low profile mono components**: the result is that today it is **almost impossible** find or exploit mechanically faulty roulette.

In conclusion? The game on biased roulettes in most casinos today is not practicable, however the fact remains that wear (which certainly does not spare online roulettes) continues to erode roulette over time, that's why I realized **a software bot** just to monitor online roulette h 24, designed for **intercept a defect as soon as it begins to appear**.

I come immediately to the final question: **but today there are online biased roulette?** Even if modern single-component roulettes will never allow you to achieve the huge winnings of the past, they can still have small wear defects, of limited size, but sufficient to make a decent profit. Certainly you cannot expect to carry out real raids like those that, for example, the Spanish ► Gonzalo García Pelayo led to Europe with his family in the early 90s.

**The terrible Spaniard**

Record producer and math enthusiast, Gonzalo García Pelayo owes his fame to the big winnings he made playing roulette in casinos all over the world, after inventing **a legal method** to win, based on the statistical analysis of the draws, in order to identify any favorite numbers, due to the imperfections of roulette.

The method was based on the fact that roulette tables inevitably have mechanical imperfections and that these **they generate a trend** which causes some numbers to have an output frequency **higher than the theoretical one**.

After collecting the results of several thousand spins and entering their data into software developed for this purpose, Pelayo discovered that a casino roulette in Madrid tended to favor certain numbers, on which it was certainly worth betting.

Organizing himself with some members of his family, he began playing at the Casino Gran Madrid from the end of 1991, managing to win by the summer of 1992 something like 70 million pesetas in that casino alone!

His system was simple: **he played only and exclusively the numbers considered favorites**, without bothering to disguise his strategy.

The management of the Madrid casino, suspicious of the ways of winning, began to follow his moves more closely until, after a win of around 500.000 pesetas in a single day, they banned Pelayo and his family members from re-entering. in the casino.

The members of the Pelayo family therefore begin to travel to play in various casinos around the world: Las Vegas, Australia, Austria, Denmark, Holland.

In total, the García Pelayo family is estimated to have earned over 250 million pesetas (1,5 million euros today), although the total amount has never been revealed.

His case also became a 10-year legal battle in Spain.

In 2004 the Spanish Supreme Court returned to the Pelayo family the right to enter any casino in Spain from where it had previously been banned.

The motivation for the sentence was that "it cannot be defined as cheating, if the player does not intervene in any way to influence the outcome of the game".

The story of Gonzalo García Pelayo and his family was also the subject of the book ► The Fabulous Story of Los Pelayos and a Breaking Vegas documentary ► The roulette assault.

Director Eduard Cortés directed the film in 2012 ► The Pelayos, loosely based on the real events experienced by the Spanish family.

**How to spot biased roulette **

Haven't you fallen asleep yet? Well, because now I'm going to tell you about the logic on which the bot is based **Roulette Bias Sniper**.

The work done by Pelayo in the 90s was fantastic, finally someone was able to use their mathematical and computer skills to really make a huge profit at roulette and I can only admire Pelayo for what he designed and built, but above all thank him for having freely shared the whole theoretical part of his method online.

If you do some research on the net you shouldn't have much difficulty finding the same content that I translated from English and that I report below to start introducing the topic in more detail.

**Pelayo's original method**

To find a possible defect (bias) of a roulette, since we do not have it in order to make the necessary physical measurements, we must resort to**statistic analysis** of his habits.

It is important to establish whether a roulette has a behavior that "deviates" from what we should expect for a perfect machine and, in order to achieve this goal, we must first analyze how a perfect and flawless roulette normally behaves (**Random Wheel**).

For this particular purpose Pelayo has created the concept of "**positiveness**": If after 36 spins a number comes up only once, we will have no positive or negative value in our cash, that is, we will be in balance, if it comes out twice, we will have a positive (+1), if it comes out three times, we will have two positives (+2), etc. if it doesn't work at all, then we have a negative (-1).

Please note: this calculation **it is based on the actual payment of the number, not on its average sortie frequency**, which we know to be once every 37 spins.

What positive value can a number achieve after a certain number of spins in a flawless roulette wheel? Or, what are the limits of randomness?

Pelayo has developed software to play a perfectly random game, that is, without any roulette flaws, and has simulated millions of random spins.

From the simulations he realized he needed them **at least 2.000 simulations for each group of numbers** considered, increasing these groups at intervals of 100 spins at a time.

For example, for the 1.000-spin block, it processed a total of 2 million spins and did so for each single spin block. Let's look carefully at the following tables:

If we analyze the first **group of 300 spins**, we observe that the sum of the “positives” (values higher than the standard expected rate in cycles of 36 spins), in a wheel without defects, is on average about +37 (second white column).

**This is the simple reasoning to follow:** every 300 spins, each number will have to sortie at least 300/36 = **8,33 times higher** to allow us to at least break even with the cash.

This means that the numbers rolled 8 times will make us lose slightly and those rolled 9 times will make us win something.

If a number is rolled 14 times, it is clear that it has a positive value equal to 14 - 8,33 = 5,67 which we will round to **+5**.

Suppose that after 300 spins the same situation also occurred for other 6 numbers, so we will have a total positive sum of the table equal to: 5,67 + 5,67 + 5,67 + 5,67 + 5,67 + 5,67, 5,67+ XNUMX = **39,69**.

Since no other number has come up more than 9 times, let's say that at this specific table, after 300 spins, we have a positive sum equal to **+39**.

From the table we can see that the table is slightly over the expected allowance for a table without defects (random wheel), that is **+37**, but in any case this value is far from the "**Soft Limit**”Which in the scheme, for the tranches of 300 spins, is **+46 **(first white column).

What is the "**Soft Limit**"? It is the maximum positive value **Not reached** in 95% of the 2.000 simulations of each spin group.

Only the remaining 5% of the tests exceeded this limit, so we can say that it is difficult to overcome the Soft Limit, since in the wheels without defects it happens only 5% of the time (1 time in 20).

What is the "**Hard Limit**"? It is the maximum positive value reached only once during the 2.000 simulations of each block. It follows that the probability of this happening is only 0,05% (1 time in 2.000) and it is** the ideal value that we must seek**.

The example of the previous table, with its positive value +39, does not highlight anything particular about this roulette; some numbers just came out more than others, but not significantly enough.

It would certainly have been interesting if the sum of the positive numbers had been +50, as overcoming the Soft Limit (+46), it would have made us think that the table was heading in the right direction.

The real wonder would have been for example, if the value had been +64, which would have clearly indicated the presence of a table with a really strong deviance, which would allow us to make sure gains.

When testing the 300 spin tranches, Pelayo did not consider the possibility of immediately encountering these values, as **you need a lot more spin** for a reliable statistic, given that the best table ever found (we will call it a "**A**"), With only 300 spins it had reached a positive value equal to only +39.

Let's pause for a moment in our illustration to better understand what a "table" is.**A**","**B**"Or"**C**"(Third / fourth / fifth white column of the table).

**Classify biased Roulette**

If we have recorded sufficient data (**almeno** **5.000 spin**), collected from what we are sure to have always been the same table, by consulting the previous table we will see that the average positive value of a roulette without defects after 5.000 spins is about +109; if the value exceeds +143 (**Soft Limit**) we are faced with something interesting and if the value exceeds +192 (**Hard Limit**), we are in the presence of a real mine!

This is what happens in the presence of a "**A**”, Which at this point dissolves all doubts, having been passed the*'*Hard Limit, on the certain presence of defects (*bias*).

In fact, we have more than 99,95% probability that positive numbers will continue to increase their deviance from the standard one.

Many of the roulette tables drawn during Pelayo's surveys were of type "B", with a positive value of +153 (again on a sample of 5.000 spins), while the worst (but still profitable) and with "slight" defects have reached a value of +135, always close to the Soft Limit values (+143).

Pelayo began the attack **when the table exceeded the Soft Limit**, still having one **95% certainty** that the table was biased.

With this data Pelayo thought that it was definitely worth risking 5% of the time to make a mistake, as having exceeded the Soft Limit, **only 1 time in 20** the table does not deviate towards the*'*Hard Limit, beyond which, it is impossible for the positive value to return towards the Soft Limit: **no wheel that exceeds the 'Hard Limit come back!**

If the roulette, after passing the Soft Limit comes back (1 time out of 20 as we have said), we simply stop betting at that table and in any case any losses are amply repaid by all the other times in which this does not happen.

If we have registered 10.000 spins from a table (registration can take place at intervals of different hours or days, but we must always be 100% certain that the throws have been registered at the same table, without any elements being replaced, then we must take note of any physical detail - scratches, imperfections - that assures us about this), we certainly have a clear data on what it can offer us.

Even if it has very slight defects (table type "C"), to be attacked with profit, **absolutely must have exceeded the Soft Limit** and have reached at least +195 (value referred to 10.000 spins).

If he has not reached these values, it is best to forget about that table, as it has no advantage to offer us.

When a flawless table (Average Random Wheel) reaches and exceeds 30.000 spins, its standard average and Soft Limit*,* begin to decline and that descent is bound to continue to the point where, after many thousands of spins analyzed, **there will no longer be any number with positive values**, having the house advantage nullified any effect of a positive deviation from the expected standard value for a flawless table.

But if the table has any flaws, some numbers will go beyond the normal values and continue to do so.

**Even a type "C" table will surpass the 'Hard Limit, while still guaranteeing a safe profit. **

If the table is of type "A", after 30.000 spins it will have reached the stratospheric positive sum of **+966**, which is impossible to register at a flawless table, whose maximum limit in total randomness is only **+294**.

If still not clear, the value +966 equals a net gain of 966 payments of 36 units each, do the multiplication and see how much it equals in terms of payout without any wagering progression required.

**Pelayo's strategy for betting on biased Roulette**

When we find a roulette that has surpassed the*'*Hard Limit, the procedure to follow is simple: **you have to bet every number that is positive**.

If only the Soft Limit has been exceeded, **we must only bet on those numbers that have reached a positive value +8**, in order to avoid false positives generated by pure chance.

The study on roulette habits with slight or obvious defects (Tables of type "A", "B" and "C"), was performed with computer tools that reproduced a behavior very similar to that of real tables, in this way Pelayo and his family (he called them the "submarines" when they entered the halls to record the releases) were able to hypothesize the possible level of advantage obtainable from the monitored roulette wheels.

For example, considering 1.000 spins, a table of type "A" should yield the equivalent of 30 full numbers, for a table of type "B" the payout drops to 20 full, while a table of type "C" on average guarantees a profit net equivalent to winning 12 full.

Based on these values, Pelayo had worked out a winning forecast of around 70 million pesetas, which was confirmed by the real events that took place at the Casino de Madrid during the summer of 1992.

**Roulette Bias Sniper**

Well, after the theory let's move on to practice: with this online roulette software I wanted to create a tool that, starting from the same logic successfully adopted by Pelayo, would adopt a series of measures that are better compatible with today's online gaming.

First of all, let us immediately clarify that **it is a bot**, that is, a program that bets itself, so you don't have to manually record thousands and thousands of spins; if Pelayo had this technology and online casinos available 20 years ago, he probably would have become a billionaire.

Just think about the travel costs for the whole family, the hours spent recording spins incognito, the stress of betting at a crowded table at the weekend, in short, it was certainly not an underpaid job, but it was in effect a job. stressful.

From this point of view a bot is the perfect ally, by now you can find traces of roulette bots daily in videos on YouTube, where you can see examples of excellent programming, the problem is that, however, more and more often I open videos where I see bots who bet on software roulettes, which by definition are not real roulettes, but follow the logic of slot machines.

If you do not have a winning system, a bot only serves to automate losses, if on the contrary you have a winning system, a bot is the ideal tool, because it has no management costs, it does not get tired, it does not get nervous, it must never go into bathroom, remains lucid and merciless even while we sleep blissfully.

**How do you think Roulette Bias Sniper (Bet brain)**

The betting method is based almost entirely on Pelayo's original method, on which I hope there is no doubt at this point that it is **a truly 100% winning technique**; so why on earth change it?

In fact, every now and then I think: but if this winning method has been explained in detail online for years, why hasn't anyone built a bot before? Why do I keep seeing online only bots that play double on software roulette or that try to predict its random behavior with some imaginative algorithm? Could it be that whoever made it keeps it (rightly) only for themselves? Or is it mathematically certain that all online roulette cannot be biased?

I tell you my opinion on the subject: biased online roulettes exist, only that with the manufacturing method adopted today (single-component), it takes much longer before a defect (however slight) can manifest itself, moreover even if a roulette is not defective, even a slight inclination of the table is enough to generate an anomaly in the frequency of the numbers.

Secondly, online casinos also monitor the outputs of their roulette wheels and they too notice if something is wrong, but at this point they have 2 possibilities: either they immediately change the defective part with considerable costs (because if they are single-component, the 'separator ring and not just the single box), or they do absolutely nothing, at least until they realize that someone is winning more than it would cost them to change the defective component. What would you do instead of the counter?

Between the two possibilities there is a well-defined time, which is the time that passes from when the roulette bias materializes, to when the dealer notices it.

In this time it fits **Roulette Bias Sniper**, as with the few but substantial changes I made to Pelayo's original theory, he tries to identify the defects (slight or obvious) and immediately start trying to profit from them for the player, even if he is working, sleeping or doing everything is more than staring at a screen with a spinning ball.

**Online tracking options with Roulette Bias Sniper**

I want to immediately reassure you about one thing: **using this roulette bot is very simple.**

**WARNING! **from the version **8** Roulette Bias Sniper uses the new graphic recognition engine **Screen Capture Engine** downloadable for free at this ► link. So you will have to use both software at the same time.

As we have already said there**he basic strategy is that described by Pelayo** and in this post I will illustrate only **the main features** of the program, for the configuration and the detailed explanation of the game options I prefer **make videos** specific and publish them on the ► Youtube channel di ThatsLuck, I therefore advise you to subscribe and activate notifications if you want to stay informed about the publications that will surely follow.

**Main Options of Roulette Bias Sniper**

► Automatic registration of outgoing numbers.

► Automatic saving of spins in a text file (very useful in case of PC crash, sudden power failure, etc.).

► Possibility of **switch off** automatically the pc upon reaching one **Stop Win** or one **Stop Loss**.

► Ability to position the bot in the foreground so that you can keep the casino window full screen (**stay on top**).

► Ability to place the casino window in the foreground so that it is never covered by popups or other casino advertisements.

► Possibility of doing **play a sound** customizable with each winning spin.

► Ability to view the bot in mode **mini**, that is, the window of the bot is reduced in height for any need for positioning on smaller screens.

► Ability to decide after how many spins recorded the counts of positive numbers and any bets must start (for example Pelayo's tables start from 300 spins onwards)

► Ability to decide how many **units by number** bet.

► Ability to use the bot **just to record spins** without ever pointing (useful for those who use other methods and want to create archives for other purposes), for this it is enough to put '0' in the field of the units to be aimed for single number.

► Possibility to set the positive value of the numbers to be bet: the original method foresees to bet the numbers with positive value at least **+8** when you exceed the Soft Limit and all positive numbers if you exceed the Hard Limit.

► Option **Bet Shield**: to protect your winnings when the Soft Limit is exceeded (because in 5% of cases the value could fall), you can set a level that, if the PV + of the table starts to decrease (always remaining above the Soft Limit), the bot however, he stops betting. To do this the bot records the maximum PV of the table (PVMax) as it grows and compares it with the Soft Limit and the PV + value. In the YouTube video I will explain this important option in detail.

► Ability to view the distribution of roulette bets and a **checkout chart**, with indication of the statistical probability (**Bias Prob%**) of the real presence of a bias calculated on the basis of the number of hits won in relation to the amount of numbers bet per spin.

**Other Options of Roulette Bias Sniper**

► Bets **anti Log-Off:** the bot bets only one base unit on red and one on black (so you only lose if zero is rolled) every tot spin when there are no real bets to make. This prevents disconnection from the game table, even if it generates a limited cost for registrations (read below how it can be calculated). As an alternative to betting the minimum on red and black, you can also bet in a way **random only on red or only on black;** in the long run the cost is the same (indeed, it actually saves a few euros), but at least the casino does not understand that the numbers are clearly being recorded.

► Comparison scheme (for consultation) between the calculations carried out by the bot and the original table elaborated by Pelayo. One of the peculiarities of **Roulette Bias Sniper** is that to calculate and compare the Soft Limit with the Positive Value of the table, it performs 2.000 random simulations **at every single spin**, in this way you have the situation under control in every phase of the game and not in blocks of 500 spins as happens with Pelayo's tables once you have exceeded 5000 spins. In the program table (**Bias Reference Table**) I have inserted a Slight Bias (mild bias) column which actually corresponds to the Pelayo table relating to the **Type "C"** (read the first part of the post for info).

In the image below you can see that we are at 1.500 recorded spins (green dots that advance over time), with a positive Table value of +73 and a Soft Limit generated by the bot of +92, exactly identical to that of Pelayo's original table ( Soft Limit in the second column in the table) which is +92. Obviously it is clear that there are not (yet) the conditions for betting on this wheel.

**Extra Tools**

► Sending an e-mail with a detailed report on the VP + level of the table, cashier, etc. This convenient option allows you to receive an e-mail (**even on your smartphone** therefore) every few minutes or hours, so that even if you are not at home or are doing something else, you can always check the status of the registrations and the cash register. It is also possible to ask for an e-mail message to be sent before the PC is turned off (**ShutDown option**) upon reaching the Stop Win or Stop Loss set in the main game panel.

► **Tracking Cost Calculator**: how much will it cost us to register 7.000 spins with Roulette Bias Sniper to a roulette wheel where the minimum bet on red / black is 20 cents? Thanks to this option you will have an idea of the costs of managing the registrations. Just enter the minimum bet in the fields, every how many spins without betting the bot must bet on the red / black (bet interval) and the number of spins you intend to register. Then clicking on the button **Calc** we will have the result, which in this case will be around 15 euros.

**FAQ**

**►01.How many numbers to bet Roulette Bias Sniper at every spin? **It depends, once the Soft Limit is exceeded, the bot starts betting all the numbers with PV + value **greater than 8** or that you decide (the Pelayo rule is **+8**). In the tests carried out so far, the bot has bet up to 7 numbers per spin. Obviously if the Hard Limit is exceeded (sure bias) they bet **all numbers with PV + greater than 0** (i.e. all the positives) which can even be 13 or 14.

**►02.What bankroll should the player have?** On this I rely on the clear indications of Pelayo himself: 1.000 units are the minimum to face the phases of negative variance even in the case of real presence of a bias. This means that if the table minimum for single numbers is 0,20 you can also start with a **initial capital of € 200**. When the bankroll reaches € 400 you move on to bet 2 units of 0,20 per full (40 cents) and so on to go up.

**►03.A table I registered exceeded the Soft Limit, but after a few hundred spins the PV + value returned to normal, why? **If you have read the first part of the post carefully, you will have noticed that Pelayo himself stated that a flawless table can exceed the Soft Limit in 5% of cases. However, if the value falls below the Soft Limit, it means that in any case there has been a phase of very strong trend of some numbers, a phase that with the precautions inserted in the bot (**Bet Shield option**), they could still lead **excellent profits** to the player.

**►04.How many spins do I have to record to understand if there is a bias or not?** At least **7.000**, in fact if you look at the table **Bias Reference Table **you will notice that I have inserted a red dot right at 7.000 spins. This is because at 7.000 spins the value of the Soft Limit and the Slight Bias (slight bias) coincide (+160), so if there is not even a "slight" bias the PV + value of the table will remain below this threshold, otherwise at 7.000 spins it must necessarily begin to rise beyond the Soft Limit (see values for 7.500 spins, where the value of the Slight Bias irreversibly begins to rise compared to the Soft Limit).

**►05.I can use Roulette Bias Sniper on automatic air-powered roulettes?** Absolutely not, you will definitely lose. The essential requirement is that there is a human being who throws the ball, so also forbid those fake roulette where there is a kind of presenter to explain the game, but the ball still starts by itself or by pressing strange buttons.

**►06.Can I raise my bet while playing if I am winning?** You could, but don't. Even if you are winning by betting 1 € per number and even if the roulette is really biased, a negative variance could start that will drain the entire cash, then maybe you add the fact that the VP + of the table falls under the Soft Limit because you are in 5% of the cases mentioned above (it will happen) and the damage is irreparable! **The ideal bet value must be equal to the bankroll divided by 1.000** (see FAQ n.2)

**►07.Can I use this bot on more than one pc?** Yes, if you have more than one PC at home you can easily do it, indeed I recommend that you run it directly from a USB key, so if necessary you insert it based on which PC you want to use or how you decide to manage your online monitoring stations. .

**►08.How do the bets take place? At even mass or with a progression?** Always and only at equal mass. If there is a certain advantage, even mass is the least stressful solution (Pelayo also played like this), even if over time you can easily increase the value of the betting unit (see FAQ n.2 and n.6).

**►09.How to configure Roulette Bias Sniper? Is it difficult to use it? **To understand how the bot works, it is enough to understand Pelayo's original method described at the beginning of the post, once you have learned that it will be very easy to understand everything else. On the **►**Youtube channel di ThatsLuck you will find a specific video for the capture engine setup **►**Screen Capture Engine and a specific one for the use of **Roulette Bias Sniper**.

**► 10. Does the bot work on all online casinos? **The tricky part of the programming was precisely that of detecting the numbers released on the screen. In the video on the setup I will explain everything, however the bot thanks to the new one **►**Screen Capture Engine detects what it sees on the screen and does not interact in any way with the programming code of the casino website's web pages. On the one hand, this means that the initial setup is a bit boring (only done once per casino), but on the other hand the casino cannot block the tracking, I have been using this technique since 2012 without ever having any problems.

**►11.But does this bot really win at roulette? **If roulette has even a slight bias of course **YES 100%**, otherwise you lose the amount invested to record the spins (see Tracking Cost Calculator option). Then there are the situations when the roulette registers a potential bias due to a strong frequency of some numbers, in this case you could also achieve good winnings, the important thing is to understand in time when the deviation of the numbers is returning and stop (StopWin ) before the winnings are exhausted (aspect managed by **Bet Shield option**).

**►12. In the videos on YouTube I have seen that the neighbors of the bet numbers come out often, is it possible to bet on those too?** No, because if there is really a bias, roulette will only start producing winnings on specific numbers, the others will come out with their normal frequencies, without bringing us any advantage in the long run.

**►13. Is there a recommended strategy? **Of course, if you don't want to take any risks, you can do this: invest just the expected amount to register 7.000 spins. Once this is done, you will have a certain idea as to whether roulette is biased or not and you can eventually start betting. To do this, just put the value "0" in the field **Bet Units** and wait patiently for the end of the registration, which can also take place on several different days, as long as the roulette is always the same. If, on the contrary, you prefer the action, leave the value "1" in the Bet Units field and check the situation on the way towards 7.000 spins, it will sometimes happen to start betting already after a few hundred spins if the PV + of the table exceeds the Soft Limit.

**►14.How do you get Roulette Bias Sniper? **You can download the software right away from the link below. Once you have seen the videos on the Youtube channel and learned all the main functions, you can buy the manual on Amazon, in which you will find the **activation code**.

Well, before you download **Roulette Bias Sniper** from the link below, remember this is one **detection tool for the game of roulette **and as such, to exploit its potential to the maximum, it must be fully understood in its operation, even if then it is enough to make a simple click to activate it.
