Boulder Dash takes place in a series of caves, each of which is laid out as rectangular grid of blocks. The player guides the player character, Rockford, with a joystick or cursor keys. In each cave, Rockford has to collect as many diamonds as are needed and avoid dangers, such as falling rocks. When enough diamonds have been collected, the exit door opens, and going through this exit door completes the cave.
