The object of Nim is to make the other player make the last move. You and the computer take turns removing any number of stones greater than zero from any one pile. Click "New Game" to start a new game. On each turn click on any marble and that marble, and all marbles to the right will be removed. On your first turn you may opt to pass and let the computer go first by pressing the designated button.
Game inspired by the Pearls Before Swine game at transience.com.au .
