[00:02] little different. In today's video, we're going to explain why the house always wins and how, in the long run, you'll always end up losing all your money at a casino. And believe me, it doesn't matter what systems you use, what
[00:15] foolproof strategies you've heard about, or any revolutionary technique that internet gurus tell you about. Every casino game is designed for the casino to win. But today we're going to focus on
[00:27] the most famous of all: roulette. We're going to expose this game, since you've probably wondered at some point why casinos always win, what variables they use in their favor, and whether the games and roulette wheels are rigged. Well then, get
[00:41] comfortable, because we're about to see. Let's start with the basics for those who game of chance where a croupier spins a wheel with numbers and colors and releases a small ball. Where it will land... well, that depends entirely on chance. The roulette wheel
[00:55] is divided into 36 numbers, half red and half black, plus... The zero in European roulette and the double zero and zero in American roulette are the only numbers that are neither red nor black, but
[01:08] green. This makes the total number of numbers 37 in European roulette and 38 in American roulette. The thing is, in each round, the croupier spins the wheel and releases a small ball in the opposite direction of the roulette wheel's rotation. Players
[01:23] have previously bet on where the ball will land. Bets can be placed on a specific number, so the ball lands on a red or black number, or on whether the number will be even or odd. You can even bet on groups of numbers. If you guess correctly by betting
[01:37] on a single number, you will receive your bet multiplied by 36. If you split your bet equally between two numbers, you will receive your bet multiplied by 18. If you bet on a dozen, you will receive your
[01:52] bet multiplied by three. Or, for example, if you bet on red and guess correctly, you will receive double your bet. You get the idea,
[02:05] Because the casino always tends to win. The answer is...  It's quite simple and we find it in mathematics; the trick to it all is not in the 36 numbers but in the zero in the case of European roulette and the zero and the double zero in
[02:19] the case of American roulette. Let's do some quick calculations: in European roulette with a single zero, the house edge is 2.7%.  This means that for every 100 bets, the casino expects to win an average of 2.7. But in
[02:34] American Roulette, thanks to the single zero and double zero, the house edge jumps to 5.26, almost double. Let's put this into perspective: imagine you're betting on red or black. It seems like a 50/50 bet, right? Well, because of those
[02:50] green numbers, it's not exactly like that. That small difference is what guarantees that in the long run, the casino always has an edge on every spin of the roulette wheel. And although you might get lucky in the short term, the
[03:02] statistics favor the casino in the long run. If you want to see it more simply, let's look at another example. Imagine you always bet 10 on red. After thousands of spins, you'll see that out of every
[03:14] 100 spins, you'll have won 49 times and lost 51. Because of that single zero on European Roulette, in American Roulette, the odds of losing increase even more. Well, this small margin is enough to ensure that
[03:29] even if you have winning streaks, the casino will eventually always end up winning. But this isn't the only advantage the casino has.  The advantage the casino has over most players is that it has a
[03:42] large amount of money. In other words, the casino can withstand large winnings from players without risk of bankruptcy, while individual players usually have a limit on the amount of money they
[03:54] can afford to lose. This means that while a player may have to stop playing after losing a significant amount of money, the casino can continue operating and recoup its losses due to its
[04:07] long-term statistical advantage, which we discussed earlier. Now, someone might say, "Hey Borja, I've heard there are strategies that really work, and I have a friend who says he wins well at the casino." I'll
[04:21] save you time and money; what you've been told is a lie and unsustainable in the long run. Let's look at some of the strategies that many advocate. The most famous is the Martingale, which was already in use in the 17th century.
[04:36] The idea is simple: after each loss, the player doubles their bet until they win. The first time you win, you'll recover all your previous losses plus a profit equal to your original bet. The problem with the
[04:49] Martingale is that it requires having a certain amount of...  Unlimited money is impossible since later the roulette wheel will give a series of unfavorable spins that will completely wipe you out. Furthermore, casinos have protected themselves against large sums of
[05:03] money that could be used to implement this strategy. It's very simple: by establishing betting limits. Basically, each table has a limit, let's say 10,000. Well, the casino won't allow you to bet
[05:16] more than that amount on each spin. So, due to these limits, even if a player has a significant amount of money, they can't keep doubling their bet until they win. Sooner or later, you'll end up losing. Another critical
[05:29] strategy is the Dalbert strategy, which is similar to the Gala Martin but a bit more conservative. In this strategy, for each loss, the player increases their bet by one unit; for each win, they decrease it by one unit. The idea is that
[05:43] after an equal number of wins and losses, the player will have obtained a winning bets. The Dalbert strategy is based on the idea that there will be equal number of wins and losses, but remember that this won't happen in the long run.
[05:59] The presence of the zero and double zero means we tend to have more losses than wins. In other words, it will bankrupt you much more slowly than using the Martingale system, but your short-term winnings, even if
[06:12] you're very lucky, will also be lower. There are other strategies, such as distributing bets across many numbers on the table, betting on different sequences of numbers, using the Martingale system by tripling bets, and
[06:25] many more. However, none of these strategies eliminates the statistical advantage the casino has. Someone who has read more about the subject or seen the legendary film about the Pelayos might say, "Hey, these people
[06:37] used a foolproof method." Well, let's see if it's so foolproof. What these people did was detect biased roulette wheels with small imperfections that caused some numbers to appear more often than others. To do this, they spent nights and nights
[06:50] observing and recording the results of thousands of roulette spins to identify patterns that indicated a bias in the roulette wheel. Once they identified the numbers that appeared most frequently due to
[07:03] physical imperfections in the wheel or its balance, they... Pelayos used to bet on these numbers, giving them an advantage over the casino. The problem is that the gambling industry is this strategy is much less likely to work due to improvements in the
[07:18] quality and maintenance of roulette wheels. Modern casinos strategies and employ equipment and practices that ensure near-perfect randomness, such as regularly changing wheels, using high-
[07:32] precision wheels, or even changing table positions. Furthermore, even if this strategy were still technically possible, it involves a crazy amount of work, a very high probability of making mistakes in the notation, and it
[07:45] doesn't completely solve the fact that the casino has more money than you. I would tell you not to play at the casino because in the long run you will always lose. If you want to play, do it responsibly and with the sole purpose of
[07:58] having fun, not to seek profit. For that, there are many better options, like the ones we talk about on this channel. So, you know what to do: subscribe, like the video if you enjoyed it, and tell me what you think in the
