Nim is a stone-taking strategy game. Your goal is to avoid being the player who removes the final stone. Think ahead, set traps, and make your opponent run out of safe choices.
The board has three rows of stones. On your turn, choose one row and remove one or more stones from that row. You may take a whole row, but you cannot take stones from two different rows on the same turn. In Play vs Computer, you are Player 1 and the computer is Player 2.
This version uses misère Nim rules: whoever takes the LAST stone LOSES. If you leave your opponent with only one stone, they must take it and you win.
Watch for the endgame, when only single stones remain. An odd number of one-stone rows is dangerous for the player about to move. On Easy, the computer sometimes makes silly moves, so look for chances!
