Reversi is a two player (in single-player games between the player and a CPU) game where players alternately place stones, one at a time, on a grid. The stones have opposing black and white faces, with one of the colors being allotted to each player.

Reversi for the iPhone is a nice adaptation of the classic board game of the same name. Featuring 1 and 2-player modes, five different difficulty levels, win-loss tracking by level, and a variety of other options, Reversi is a well-executed and enjoyable app.
