The game is totally intuitive if you know how to play the real live version of Russian Roulette. Basically you have a revolving pistol, and one of its chambers has a bullet in it. You don't know which. The gamble is to shoot yourself in the head when the chamber being fired is empty. It is pure luck as to whether or not it really is empty. If you die, the others get your money.
In this version you tell the computer how many chambers you want your gun barrel to have, and then you type in the players' names. It is self-explanatory after that. The computer keeps track of who is alive and who is dead.
This is a trivial game so do what you like with it apart from infringe my copyright. I accept no liability for any loss or damage caused by you using this game.
