Eight familiar games introduce children ages 10 and up to the mind-stretching possibility of a “multiconnected universe”. Games include: tic-tac-toe, mazes, crossword puzzles, word search puzzles, jigsaw puzzles, chess, pool and gomoku. While playing the games, kids develop an intuitive visual understanding of a model universe that is finite yet has no boundary. Players who master the games in 2D may enjoy the extra challenge of solving 3D mazes and playing 3D tic-tac-toe in multiconnected 3D spaces. Even though the games were designed with kids in mind, adults interested in topology, geometry and cosmology have also found them enjoyable and enlightening.

Great games


I just saw Jeff Weeks give a talk on the shape of space - the title of his book. In it, he used this exact game to demonstrate principles of geometry that could help us understand the universe we live in. For non-mathematicians the game can help give an understanding of how different spaces behave, and add to that how fun and well made these games are and you have something that is well worth downloading.

Also - includes other two and three dimensional models e.g., Klein bottle.

Thanks Jeff!

It's a game that you'll love so much that you can do word searches crosswords (etc). But greatest thing about this game is that I have never had any crashes most apps in a couple of months time it will crash but this has sent!
