Rock'n! Monster!!

The continent is being overwhelmed by an evil league. The four heroes Rankasuta, Mirutiadesu, Pichimin, and Sarusuran compete to travel the land and restore peace.

This falling block puzzle game requires the player to line/bunch up at least four blocks of the same color to create a match. Trap blocks create a new block of a different color when matches are made against it. Occasionally a line of obstacle blocks will form, which require matches adjacent to them to get them removed. Making multiples matches in a row multiples points earned and builds up action points to attack an opponent player with additional blocks.

The game can be played in a continuous One Player mode, the Story Mode or the Versus Mode with a second player.
