If you have played Reversi before, you know that the objective of the game is to get your colored pieces out of the board, while your opponent tries to prevent you from doing so. However, in order to win, you have to take advantage of the various board shapes, as well as the different pieces that you can move. This application allows you to do just that, as it provides you with an easy-to-use interface, where you can configure the game settings, as well as the pieces and board sizes. You can also use this application to learn how to play Reversi, as it contains an interactive learning mode, where you can play the game with the assistance of the computer.

The Reversi application is available for free, as it does not contain advertisements. However, in order to support its development, it will ask you to provide a small amount of data.
