Nim

This is a variation on the traditional game of Nim.

The game starts with a pile of 34 beans. On each turn, you must take one, two, or three beans from the pile. You can't pass. You must take at least one bean on each turn. Your opponent must do the same.

The player who takes the last bean loses. So the goal is to force your opponent to take the last bean.

Before your first move, you can set the skill level of the computer player. Watch out for the Master player. She's good!
