Equation 322 of the so-called bullfight usually means that the sum of the points of three cards in the gambler's hand takes the remainder 10, and the remainder is called "Niu 3". Then the sum of the points of the other two cards is also the remainder of 10, and then compare it with "Niu 3". If the score is 0-5, it is called "No Niu" to "Niu 5", and if the sum of the integral is 10, it is called "Niu Niu". Specific rules and calculation methods can refer to the network information. However, it should be noted that this equation has no scientific basis in the actual bullfighting competition. Strictly speaking, it is just a psychological tactic or casino deception, which can't really improve the winning rate.
In the game, various seemingly magical mathematical formulas, probability analysis and data models often appear, trying to make people believe that they can predict and control the occurrence of random events. But in fact, most of these theories are one-sided and incomplete, which can not really improve the winning rate, and may even lead to greater risks and losses.
