Torus and Klein Bottle Games

Jeff Weeks has rewritten the Torus and Klein Bottle Games as a native Windows application. The new features:

  • smoother, more reliable loading and execution
  • two new games (Pool and Apples) in addition to all the old games (Tic-Tac-Toe, Maze, Crossword, Word Search, Jigsaw Puzzle and Chess)
  • available in English, French, and Italian
  • fast, high-quality graphics, expandable in any size window
  • a mouse cursor that tracks on the torus or Klein bottle itself, for a more thorough understanding of those spaces

A Mac OS X version should become available in the 2006-2007 academic year. In the meantime, the online versions are accessible here for Macintosh users:
