About KleleAtoms
Players take turns placing an atom on a tile with no enemy atoms. A tile with too many (two in a corner, three on an edge, four elsewhere) explodes into its neighbours and takes over their atoms, which can set off more explosions. Lose all your atoms and you're out.
The grid can be 5 to 13 wide and 4 to 8 high. Each of the four players can be a human, one of three computer levels, or nobody, with at most two empty slots. There's a signed build for PSPs on official firmware.
