About Three Rings

Three Rings is a developer of online games based in San Francisco, California, with offices in Philadelphia, PA and Madison, WI. We were acquired by SEGA in November 2011 and continue to operate as a development studio within the SEGA family.

Here are a few facts about the studio:

  • Three Rings was founded on March 30, 2001 to build the persistent world of puzzly piracy, Puzzle Pirates.
  • Puzzle Pirates was launched in December 2003 after over a year of alpha and beta testing, and pioneered free to play microtransactions starting in 2005.
  • Since launching Puzzle Pirates, we have shipped Bang! Howdy, Whirled (with a host of smaller games within, like Brawler and Bang! Heroes), Corpse Craft, Bite Me! and Spiral Knights.
  • We are currently working hard to bring Doctor Who: Worlds in Time to launch. Watch out for more news from The Doctor, soon!
  • We build many of our games using open-source technologies like Java, Linux, BSD and others. We have contributed back a number of our libraries as open-source and also contributed to others such as Google's PlayN cross-platform game toolkit.
  • Our downtown SOMA office space was transformed by Because We Can into a deep-sea exploration vessel inspired by Jules Verne's 20,000 Leagues Under the Sea. We lub coming to work in our Victorian submarine - even on the days when the squid gets angry!
