Game Spot: Math Games

First up: Shut the Box. In shut the box you roll the dice and use mathematical equations to turn down the tiles. If you roll a 9, you can turn down the numbers 8 and 1, or 7 and 2, or 2,3, and 4, or just 9. You get a point for each tile you flip down. When a roll produces a number where no tiles can be turned down then the round is over. This game can be played using addition, subtraction, multiplication, division or all of them.

Double Shutter is a variant of the classic game shut the box, but adds a second row of tiles nestled behind the first row. You can't use the second row until the tile in front is turned. Both games can be played alone or with 2 to 4 players.

Sumoku is a newer game in which each player gets 8 numbered tiles. You roll the dice to get your key number and build a line of tiles (without repeating colors). The line of tiles needs to add up to a multiple of the key number.
