Three-son is a kind of black and white. Three-son chess is a traditional folk game, also known as nine palace chess, circle fork, one dragon, tic-tac-toe and so on. Connect the diagonal lines of the square and place three pieces on each side in turn. As long as the three pieces of your own line, the other side will lose. However, there are many times when there will be a draw. We have learned c language, now we try to write a small game of chess with C language to play!

Chess board pattern:

Game start options:

Option 1: Start the game

Select 0: Exit the game

When you choose to start the game, you start playing against the computer

When we choose the coordinate 2 comma 2,

The computer chooses the coordinates 1,3.

There are only three outcomes:

Players to win:

Computer win:

Flat board:

You can try it yourself!!

Have a look at you and your computer whose chess skill is higher!!

The difficulty level can be adjusted by yourself:

You can decide how many squares you want
