The game play is simple. There are a bunch of playing pieces with black on one side and white on the other. Your goal is to have more of your color on the board when the game is over. You can flip your opponent's pieces (making them your color) whenever you can trap them between two of your pieces. In fact, you can only put your new pieces down in places that cause this to happen. Play goes back and forth until all the spaces are filled and then it comes down to who had the most.
