Triplets

Triplets is a strategy game. Though the rules are quite simple, the game itself is actually rather challenging!

You take turns playing against the computer, placing pieces onto the board one at a time. To win, you have to be the first to get three in a row, either horizontally, vertically, or diagonally.

The board can be changed in size from 4x4 to 8x8. Additionally, you can indicate if the computer should go first, varying game play.

This game was originally proposed by Stanislaw Ulam, a Polish-American mathematician.
