About this app

Reversi (a.k.a. Othello) is a board-game based on a grid with eight rows and eight columns, played between you and the computer, by placing pieces with two colored sides. This application is free and without any advertisements.

Game rules
Each player must place a new piece in a position that there exists at least one straight (horizontal, vertical, or diagonal) line between the new piece and another piece of the same color, with one or more contiguous opposite pieces between them.

Black color starts first move. When player cannot move, the other player takes the turn. When neither players can move, the game ends. The winner is the player that owns more pieces.

Dear friends, consider that this app doesn't contain advertisements, in-app purchases, so this app will evolve depending on your positive ratings. Be positive, be nice :-)

IMPORTANT NOTICE FOR BEGINNERS: our game performs multiple moves, as any similar application, only in case you cannot move as you don't have any valid place to go, i.e. when you have to pass your turn according to well known game rule "If one player can not make a valid move, play passes back to the other player".
