Yesterday at the MIX11 conference, Microsoft revealed a project undertaken with Soap Creative and Namco Bandai: The World's Biggest Pac-Man, an HTML 5 version of the iconic arcade game with user-created levels. Every maze is connected, allowing players to use the "exits" on the side of a maze to enter another one -- even if it feels really wrong to leave a maze partially completed (so wrong). The rapidly expanding continent of Pac-Man mazes currently includes 1420 separate screens.

The app requires users to sign into Facebook before creating new mazes, but no login is required to explore the growing selection of levels. It should run on any browser (despite being released as promotion for Internet Explorer 9), but based on our experience iOS devices aren't compatible.
