The game is divided into a series of single screen levels. The goal of the player on each screen is manipulate Blagger, a burglar, to collect the scattered keys and then reach the safe. The keys must be collected and the safe opened in a set amount of time. Blagger can walk either left or right, or jump left or right. The jumping action is in a fixed pattern and cannot be altered once initiated. Gameplay reduces to learning the best order in which to collect the keys, and correct timing of movements and jumping.
