Meta-Forms Logic Building Game

Meta-Forms is a very basic game at the start but little by little the clues become vaguer and require tons more thought. The Nine wooden shapes each have a home in the 3 x 3 grid, and the puzzle you are on gives you clues on where to place them.

This set includes a Grid game board, 9 wooden pieces and puzzle book that has 80 puzzles and their solutions. So if you would like to test your brain then you can currently get this game from ThinkGeek for $17.99.
