Nim - The Rules
Nim is a two player game that uses identical pieces aligned in several columns. You play against the computer. The players move alternatively. A move consists in removing pieces from a single column; the number of pieces removed is decided by the player making the move.
In order to move, hover the mouse on the pieces; click when you want to remove the green colored pieces. The game ends when there are no more pieces available. The player that performed that last move wins. Good luck!
