If you've played ... well, any Sega games, you're probably aware of the company's unhealthy fixation on rings. Sonic can't get enough of the things. Ecco the Dolphin will defy the laws of gravity to pierce them. Today, the publisher further developed its addiction: Sega has announced via a press release that it has acquired San Francisco-based Spiral Knights developer Three Rings.

The company's got plenty of street cred, thanks to its well-received pseudo MMO Puzzle Pirates, and its upcoming online game set in the storied Doctor Who universe. Still, that's probably not why Sega bought them. It's because they have rings, you guys. Three of them. If there were a company called Five Rings, or Ten Thousand Rings, Sega probably would have bought them instead.
