http://en.wikipedia.org/wiki/Xi_(video_game) http://www.youtube.com/watch?v=ieU88Ts4RsA This was prob one of my favorite sleeper hits of the PS1 and all-time think it would be great on iphone or least a clone of it. Very unique cube rolling dice game. All the game modes were a blast and multiplayer was awesome too if not a lil too confusing with 4 players but a one on one would be great on iphone. IGN had gave it a 9.0 when they reviewed it.
