Reversi Online is a free Android game developed by Arturo Gutierrez, falling under the category of puzzle games. It is an online multiplayer version of the classic strategy game, Reversi, where two players take turns to place their counters on the board, attempting to capture their opponent's counters. The objective is to have a majority of your counters on the board by the end of the game.

The game offers two modes of play - against Android or online against other players. The online mode supports player rankings and achievements and includes a leaderboard of top-rated players. You can also choose to upgrade to the Pro version, which is ad-free, via an in-app purchase. The game is easy-to-use, and the graphics are visually appealing.
