The Theoretical Game.
Game Theory as a cell phone multiplayer Java game.
Should work fine on any modern cell phone. Might look wonky (but playable) on 'small' screens (My own phone is a SonyEricsson S700, which has a rather large screen).
The menu option to play against an AI doesn't work -- the AI isn't done yet ;)

How To Play
You must be two players to play this game. The first player plays green, chooses columns, and uses the keys 1, 4, 7 and *. The second player plays blue, chooses rows, and uses the keys 3, 6, 9 and #.
The goal of the game is to guess which row/column the other player will choose, and then select the column/row that marks the cell with the most points in your own color. You may change selection as many times as you want during a round, but when the time runs out, that selection is final, and points are handed out. If one player fails to make a selection before the time runs out, the other player wins two points.
For an example, look at screenshot #5 above. In that shot, the round has just ended. Green player chose column #1 by pressing "1". Blue player chose column #2 by pressing "6". The cell that crosses this row and column is chosen: In this case, that cell has a blue number 1 in it, which means that the blue player gains one point.
