Chew Man Fu has set a curse to rob the world of fried rice, egg rolls and all its other favourite foods. To stop him you must work through 550 rounds, clearing them by placing four different coloured balls into the appropriately-coloured hole.
The gameplay is something of a Pengo variant, as the single-screen levels are inhabited by enemies, who can be killed by firing one of the balls at them at speed. When it hits one it will continue moving in the same direction, rebounding off walls if neccessary, and pushing you backwards slightly if it comes back to you - but it can be instantaneously brought back under control.
Blocks can also be moved at a more casual speed, including round corners. Once a block is placed onto its spot, it can be used again as a weapon. The levels are in a maze style, and parts of this can be opened up. The game also includes a small bonus Kick-Ball game for 2 players, which doubles as practice with the control system.
