Dominoes classic, duel for PC

A board game in which a chain of dominoes ("bones", "stones") is built, touching halves with the same number of dots indicating the number of points.

The game can be played with artificial intelligence or with an opponent online in multiplayer mode.

A classic set has 28 dominoes, also called stones or bones. These rectangles are divided into 2 parts, each with dots from 0 to 6.

Two players play the game. At the beginning of the game, 7 bones are dealt to each player.
The remaining ones are kept aside in reserve, with the clean side up (on the market).
The player who has a double 6-6 starts, he puts down a bone. The next players put down 6-1, 6-2, etc. If there are no such stones, then you need to get them from the market. If none of the players has a 6-6 double, then move others, for example 5-5, 4-4, etc. from higher to lower. And if no one has a double, then move higher stone values, for example 6-5.
After the first move, the players take turns placing suitable chips with the same value as the last one placed on the table. If there are no suitable ones, then additional ones are taken from the reserve (at the market). The more bones a player takes from the reserve, the further he is from winning, since in dominoes it is not profitable to have many tiles.
The game ends when one of the players places his last stone. The winner is credited with the sum of the points of all the stones remaining in the loser's hand. The game can end when there are stones in hand, but nothing to report - "fish". In this situation, the winner belongs to the one with the least points. The difference in points is recorded as his win.
In a new round, the first move is made by the winner of the previous round. The game continues until a pre-agreed amount is reached: 50, 100, 150, 200, 250, 300 points.
