Pick an option at the start. Vs person is playing against someone next to you. Vs pro bot is against a really really smart robot. Teach a bot is playing against a robot that gets smarter after each loss. The squares represent pawns in chess. To move click on a pawn in your color and click on the square where you want to move it. You can move 1 space up only if there is no pawn in that space, or you can move 1 space diagonally only if there is an enemy pawn in that space and then you capture that pawn. The variable in the upper left hand corner tells you whose turn it is. You can win in 3 different ways. 1: Getting one of your pawns to one of the 3 spaces where an opponent's pawn began. 2: Capture all of your opponent's pawns. 3: At the start of your opponent's turn they can make no legal moves.
The bot will always go second no matter what. The person going second will always win if they know the right moves. The pro bot is pretty much impossible to beat.
