In addition to its better-known hits like Defender and Sinistar, Williams released a number of rather oddball games during its 80s run as one of America's dominant arcade manufacturers. Bubbles was one of those games, a curious experience that puts players in control of a sentient soap bubble whose job is to clean up his resident sink of ants, crumbs and grease while avoiding sponges, scrub brushes and razor blades (truly a gritty slice-of-life concept). Your bubble grows over time, gaining a somewhat creepy face as well as the ability to fight back against your cleaning rivals, and you can also steal a broom from a tiny cleaning lady to swat roaches and other enemies. In addition to its status as an arcade curiosity, Bubbles was also one of only a few games that got Williams' Duramold plastic cabinet treatment.
