Query: Simpler than checkers, but with amazing depth.

This game is a must have for anyone who likes classic strategy games like reversi, checkers, and even chess. Turn based gameplay creates a clear set of strategies for opening, midgame, and endgame phases. The AI seems quite good too with the lower levels playable for newbies, and the higher levels challenging. This game rarely leaves my Gameboy.
