Blagger is a platform game created by Antony Crowther for the Commodore 64 and released by Alligata in 1983.

The goal of the player on each screen is to manipulate Roger, a burglar, to collect the scattered keys and then reach the safe.

Gameplay involves learning the best order in which to collect the keys, and good timing of movement and jumping.

Blagger will die if he touches cacti, one of the moving enemy obstacles of the level, or if he falls more than a certain distance.

The movement of the enemies is in a fixed pattern, generally travelling from one point to another and back again.
