The basis for the creation of virtual casinos are standard mathematical rules that allow the institution to receive a constant profit. And in order to clearly explain the system of gambling entertainment for the casino, just enough to have a piece of paper and a pair of dice for dice.

Contrary to the common belief that you need to have a certain baggage of knowledge to develop an effective structure, here is an example of a gambling entertainment for gambling establishment, based only on the theory of probability. The rules of the game will be elementary: the sheet of paper draws special cells with numbering from two to twelve, which each gambler will be betting. Each player has the right to put on one or more values. After these preparatory manipulations it is possible to proceed directly to the game: if we throw two cubes at the same time, we will get the sum of points from two to twelve. If the players guess the result of the roll, they will receive a cash reward. And in the case that the participants do not guess the value - all cash contributions will be redirected to the casino bank.

This scheme is incredibly simple, but there is a fair question about the size of the payout, because then you need to set a certain coefficient, which would be acceptable for the gamblers and profitable for the gambling establishment. In addition, the correspondence of the amounts should attract the gambler, creating the illusion that it is big and easy money. To make accurate mathematical calculations, you do not need complicated projects or formulas, it is enough to correctly calculate the number of game combinations involving one or another number of points. If we are talking about just two dice, this procedure does not take much time or effort. Consider the order from top to bottom:

- Twelve points are obtained from one combination on the dice: six and six.
- Eleven points from two: five and six or six and five.
- Ten points is obtained from three combinations: five and five, four and six, six and four.
- Nine points are: three and six, six and three, five and four, four and five.
- Eight points come out of combinations: four and four, three and five, five and three, two and six, six and two.
- Seven points: one and six, six and one, four and three, three and four, five and two, two and five.
- Six points come from combinations: three and three, four and two, two and four, five and one, one and five.
- Five points are the combinations: four and one, one and four, three and two, two and three.
- Four points are derived from the following three combinations: two and two, three and one, one and three.
- Three points: two and one, one and two.
- Two points come out of one combination: one and one.

According to the data given in this table, it appears that twelve points can be obtained from one combination, and seven points from six combinations. Thus, there are thirty-six different combinations, the sum of which can be obtained by squaring the six.

Now it is necessary to make elementary calculations of the probability of falling out a certain value. To do this, divide the total number of combinations by the number of all possible combinations:

- Twelve points - 36 : 1 = 36.
- Eleven points - 36: 2 = 18.
- Ten points: 36 : 3 = 12.
- Nine points: 36 : 4 = 9.
- Eight points - 36 : 5 = 7.2.
- Seven points - 36 : 6 = 6.
- Six points - 36 : 5 = 7.2.
- Five points - 36 : 4 = 9.
- Four points - 36 : 3 = 12.
- Three points - 36 : 2 = 18.
- Two points - 36 : 1 = 36.

It is not very difficult to calculate that the payout ratio of winnings will be the resulting figure of each particular value. If there are no integers, such as 7.2, then round up the value to 7. However, it is worth mentioning that such calculations are carried out according to the principle of fair payout, that is, the gambling establishment and the gambler receive equal chances of winning or losing. Naturally, if a similar equilibrium were in effect in every gambling house, then absolutely each of its visitors would have all chances to leave it with a winnings. But by rounding the value of 7.2 to seven, we have made a slight advantage for combinations with six and eight points.

Usually the casino does not aim to establish a large advantage over the player, which he can quickly determine.

The main goal of a gambling establishment is an income that will allow a quick payback without being noticed by the players. To accomplish this, you need to set a personal percentage, as a rule, it ranges from one to thirty percent. And it does not necessarily have to be fixed for all betting levels. Most often they are expressed in rounded numbers for greater ease of application.

Let's look at an example again. So, first, let's set the average bet at ten percent, thus honestly paying the gamblers 90% of the equal balance. To make the calculations, all previously obtained odds are multiplied by 0.9 and rounded:

- Twelve points is 1:32.
- Eleven points is 1:16.
- Ten points is 1:12.
- Nine points is 1:11.
- Eight points, 1:6.
- Seven points, 1:5.
- Six points, 1:6.
- Five points, 1:11.
- Four points, 1:12.
- Three points, 1:16.
- Two points, 1:32.

That's basically the whole system. Regardless of the size of the bets and the duration of the game, the bank will always make a profit. Thus, dispels all the myths about fraudulent gambling establishments. Casinos do not need to implement hidden methods to cheat customers, they use simple mathematics to calculate their income and the amount of winnings paid to players. At least, the casino I play (I prefer games casino Azart Play), always honest and open.
