This is a puzzle game in which players must explode all of the bombs in each level using a spark. The spark flows along a fuse, which is made up of a series of tiles. These tiles can be moved in the manner of a sliding puzzle. In other words, there is only one unoccupied space and adjacent tiles can be moved into that space, freeing a new space in the process. The aim is then to move the tiles so that the fuse forms a path from the spark to each bomb. There is a time limit, however, and extra time is knocked off if the spark reaches a dead end. Some levels also contain water droplets that extinguish the spark if they touch it.
