Torus Games

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 apples. 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 on the torus may move on to try them on the more challenging Klein bottle. Even though the games were designed with kids in mind, adults interested in topology, geometry and cosmology have also found them enjoyable and enlightening.
