After getting a message from King Clown that strange blue bombs have appeared on all six worlds, Kid Clown sets on a mission to clear away the threat. You control a character whose purpose is to blow the blue bombs scattered on each island to smithereens.
You must place the red bomb in a way that it will trigger all the blue bombs at once. The number at the top of the blue bombs shows how far the blast will reach, helping you plan your strategy.
The stages are designed like chessboards with little details like trees and water on the first island, lava pits on the lava world, and so on. You can rotate the levels in an isometric view (top-down if you hold down L2) and there's a time limit to complete each stage.
