Bubbler is a two-player Action Adventure game rendered in Isometric Projection. It was developed by US Gold and released under the Ultimate Play the Game label in 1987, on the ZX Spectrum, Amstrad CPC, and MSX. A Commodore 64 port was commissioned but never released.

While most isometric games of the time allowed the character to move in four directions (six if they included up and down),[1] Bubbler took a more Marble Madness-like approach and let it turn any horizontal angle. Naturally this was used to make the game more difficult, with plenty of narrow ramps and ledges to fall off.

The main character is a political prisoner whose body has been magically degraded into a squishy blob. Fortunately one of his fellow-prisoners managed to give him the ability to throw fireballs, and now he's wondering around his prison shooting monsters.

The name Bubbler comes from a number of magic bottles that release bubbles containing evil monsters. The aim of the game is to cork all of the bottles, reducing the Big Bad's power in the process, then escape the prison and free the city.
