Sonic Reversi (ソニックリバーシ[3] Sonikkuribāshi?) is a mobile phone game released as part of the Sonic Cafe service offered by Sega. This game later received a sequel titled Sonic Reversi Hyper.


In this game, the standard, board game format of reversi is played as Sonic against other characters. A practice match against a Chao is also available. The player plays for (and can lose) Rings, as well as national rankings via a high-score server.

The in the main game, Official Match (公式戦[3] Kōshikisen?), can be played up to three times a day as it requires Rings to access. Three Rings are provided each day, with them collecting until the player has fifteen.[4] The opponent is decided via a roulette, with each character featuring a different prize pool (ex. Knuckles = $6000, Shadow = $10000[4]). Also, each opponent is set at a different difficulty.
