In the luxurious suite on the 31st floor of the Golden God Hotel, the Celtic players sat in a circle around the bed, with Fox Leon sitting on the bed with a deck of playing cards in his hand. Just as he explained tactics in training, he was giving these beginners a unique gambling lesson.

"First of all, I went from $100 to $10,000 with roulette, and while it's a gamble that's basically pure luck, that doesn't mean he's out of luck. There are two problems with the roulette game, first of all, the roulette wheel of the Golden God Casino rotates quite fast, faster than the general roulette wheel, which means that the randomness of the ball distribution will become higher; The second point is that the Golden God Casino's roulette wheel allows bets to be placed when the ball is not fully in the wheel, and only when the boundary is spinning, which is a very crucial point, and the few times I have won big stacks have been placed while the ball is spinning on the boundary. ”

Leon began to explain how he used the roulette wheel to win from $100 to $10,000. The roulette wheel of the Golden God Casino is not only luxurious, but also fast, and it is extremely difficult to judge the position of the ball from the probability. So Leon tried to use his memory to calculate the probability of betting to win chips in the first few minutes, but this high-quality roulette wheel made him have to choose to give up.

"Next, I began to observe the dealer's habit of starting the ball, the strength of the ball. For a good dealer, he needs to try to achieve the randomness of the starting ball, but this is not possible for people, and countless opening shots a day will allow him to develop muscle memory and achieve the most suitable and durable starting force. Then I found out that with the strength of the dealer's kick-off, the ball is more likely to appear in the third, fourth and sixth blocks. "There are multiple metal blocks on the track on the outer wall of the roulette wheel to increase the randomness of the ball falling into the wheel, but the dealer's inertia in strength is caught by Leon. Knowing where the ball will land means that you can determine which colour zone the ball will land on based on the speed of the wheel's rotation and initial orientation.

But that's not enough, Leon continued: "The trajectory of the ball is very difficult to judge after it hits the metal block, and although the strength of the dealer is fixed, it is his initial speed and acceleration that really determines the ball's placement. So I'm going to start measuring the initial velocity and acceleration of the ball -- I'll draw a diagram for you. When the ball rotates on the sidewall, the component of gravity provides the centripetal force, assuming that the initial velocity of the ball falling is θ and the radius of the wheel wheel is r, then according to the basic mechanical formula, the square of the first derivative of θ can be obtained is greater than g/r*tanα, and the α is the angle between the position of the ball and the tangent line of the sidewall and the horizontal line. Assuming that the amount of friction between the ball and the sidewall is constant, the resulting acceleration is constant. The velocity of the ball will gradually slow down, and when it reaches a critical value, it will fall downward. From this we can predict how long the ball will turn, how many turns, and where it will fall, then we can deduce the formula: t is equal to the negative reciprocal of the second derivative of θ, multiplied by the first derivative of θ minus the root g/r*tanα.................."

Once he was exposed to mathematics, there were times when Leon would fall into a state of self-forgetfulness and begin to scribble on paper on his own. Completely unaware that his disciples were among the best at basketball in the world, not the best at math, Walker had closed his eyes. He felt that his head was bigger, and Joe Johnson, who listened intently in vain trying to find out the secrets, quickly chose to give up.

Leon quickly noticed this, and he put away the drawings a little embarrassed, coughed and said, "Sorry, I shouldn't be so verbose, to put it simply." I can roughly determine which baffle the ball will land on based on the formula, the team's initial velocity, and acceleration, and then determine which number the ball is likely to land on based on the speed of the roulette wheel and the timing of the intersection of the two. It took me about 10 minutes to make my prediction. I felt that guessing five numbers was a safe way to bet, and after that, I took a risk and tried a three-number combination, and it worked. Then I ended the game of roulette, because the calculations were too tiring for me, and the luck component was really big, so after accumulating a small amount of chips, I went to my favorite 21. ”

Leon finished talking about his roulette game experience lightly, everyone stuck out their tongues, knowing that they would not be able to learn this method in their lives, except for a machine brain like Leon, who else can do such complex calculations and judge the speed and position of the ball in a short time?

"21 o'clock...... This is the simplest trick, a game that no longer depends on luck but on probability, you know, if one thing can control it in probability, then you win half of the game...... Including your shots, Antoine. The dealer will continue to follow before 17 points, and at 17 points or more will end the deal, because the number of cards is limited, so the various combinations are also limited, these matrices can include the various situations in which the player takes the cards. ”

Leon said and took out a piece of paper to scribble on it, but this time it was not as complicated as roulette, he drew several matrices, the horizontal row represents the cards in the dealer's hand, and the vertical row is the cards in the player's hand, from the first round to the third round of three matrices, there are about more than two hundred minutes, each situation has two options of "continue to ask for cards" and "end to take cards", and Leon filled these choices in.

"What does this mean? Is the choice fixed for each situation? Walker asked, looking at the dizzying tables and figures, Walker had forgotten all about losing hundreds of thousands of dollars on the stud stage.

"That's right, it's a game of chance, because Split is not allowed at Golden God Casino, so it's much simpler. For example, if you have a 12 in your hand, then if the dealer's hand is 2 or 3, then you have to continue to hit, if it is 4 or 6, then please end up with the card, if it is a higher number, then you still have to continue to hit. …… Let's start with an assumption that if we don't hit after 12 points, then the dealer can only hope that the dealer will bust. First of all, the dealer is greater than or equal to 17 points, will not take the card, OK, so you lose. If the banker's starting point is 16 points, the banker will continue to draw cards, and the draw will be blown out when it reaches 6~10. We know that the probability of drawing cards of different sizes is equal to 1/13, let F(x) be the probability of continuing to draw cards when the current number of points and x is x, then: F(16)=8/13=0.61538, the probability is 0.61538, we calculate F(15), F(14), and then combine the various probabilities .................."

Leon started his probability class again, but this time his explanation was simple and detailed, and with the playing cards in his hand, he quickly made several players understand the general idea. Then he added: "In this way, taking into account all the probabilities, if you make your choice in the 21 points in strict accordance with the way given in this table, then the probability that you will win the dealer is about 49 percent." “

As soon as he heard this, Antoine Walker, who was originally attentive and eager to immediately take this watch to the table below to try it, suddenly looked like a wilted eggplant, he held his head and said: "Forty-nine percent? Less than half of it means that there are still a lot of losses in the end! “

Leon shook his head and said: "Just those probabilities are considering the situation that the number of cards is sufficient, in fact, the cards will only be fewer and fewer, the Golden God Casino has to deal most of the cards every time before reshuffling the cards, so as long as you note which cards have been used, you can change the selection strategy, the fewer the cards, the greater the probability of winning!" "Leon's memory plays a huge role in the game of 21, which is why he is invincible in 21, a game that relies on probability and memory is just too good for him.

Next, Leon taught the players the 21-point high-low memory method, and how to observe micro-expressions, how to remember cards, and how to guess cards in the stud battle. For a while, these guys who gambled only by luck felt that they had learned peerless gambling skills in an instant, and they couldn't wait to go downstairs to the gambling table and kill them immediately.

But after a while, they found that Leon was sitting on the bed without saying a word, completely different from the way he had just talked, his eyes were still cold, and the excitement of everyone was quickly cooled. He got up from the bed, walked to the cabinet, picked up the large nylon bag that he had set aside, and threw it on the bed, which contained the million dollars that Leon had won.

He said to everyone, "Now that I've taught you this, let's take a gamble." It's my bet, a million dollars, and your bet is your career! (To be continued.) )
