Nim is a two player game. In this case, you will play against the computer. When you start the game, 3 piles consisting of a random number of cards are put together. Each player must remove one or more cards from a pile. The player that takes the last cards from the only remaining pile wins. You begin and you allways have a winning configuration at the begining if you don’t make any error. To take cards from a pile just click a card and all cards (including the one you clicked on) from the right are taken.
