Win the game by ending up with more pieces than the computer. You can add one each turn, and all computer pieces between that new one, and any of your other pieces will become yours as well. It's not like Othello: you don't have to jump, and no diagonal moves. I really think the Othello rules are more thought out (better strategy). But there's already a perfect Othello game, so... Anyways, after winning a level, you go to the next (not much more difficult) level. Should at least have a 2-humans mode.
