Reversi is a strategy board game available for iPhone users. It is a two-player game played on an 8×8 uncheckered board. The objective of the game is to have the majority of disks turned to display your color when the last playable empty square is filled.

The game allows players to take turns placing disks on the board with their assigned color facing up. Any disks of the opponent's color that are in a straight line and bounded by the disk just placed and another disk of the current player's color are turned over to the current player's color.

Reversi offers an enjoyable experience for family game time or playing against AI opponents of varying difficulties. Be warned, however, that beating the best AI in this game is very challenging.

Not only can you have fun playing Reversi, but you can also earn experience points by winning against the AIs. The game offers four levels of difficulty, with each level providing a different number of experience points for a win. Additionally, the game features options like undo, save/load unfinished games, and timer-based gameplay.
