[1] Each time the player moves by one tile, a note of Beethoven's Für Elise are played using the ZX Spectrum's "beeper".

Diffusing six timebombs resets the tiles, increasing the screen number and adding one "boot", to a maximum of four.

Unlike Check Man, the player can cause a horizontal row of tiles to shift left or right, minimizing the risk cutting off a route to the bomb.

CRASH magazine's review described Timebomb as fun, noting the skill required in using the tile scrolling feature in order to reach the bomb within the time limit.

The reviewers were of mixed opinion on the game's addictivity, noting that it was ultimately a "beat the high score" experience.
