DigiDock released a Reversi type of game for the iTouch called Reversi Sister. To play the game is the same as with any Reversi games out there. The main attraction would be if the AI (artifical intelligence) is pretty good. I would say it is ok. Sometimes I am not satisfied with how my opponent plays against me and sometimes I am. This game is sort of the same in AI as the game Reversi Plus. The huge difference with Reversi Sister is that an anime character will talk, dance and cheer you up whilst playing the game. A variety of animation moves can be seen from the anime character so keep on playing new games to see them all. One other game feature includes a tip on which areas on the board are acceptable for you to tap your next move (though this feature is pretty common in most Reversi games).
The important aspect for a Reversi game is always its AI (artificial intelligence). If the AI sucks, then players would not enjoy playing the game over and over again. Reversi Sister’s AI, as I mentioned awhile ago, is decent and acceptable to me. I care only for the game play itself, if you do not like some anime girl dancing and cheering while you are playing the game, you might find it annoying. Otherwise, anime lovers would enjoy having an anime character cheer you on while you play the game.
