How were the pyramids built? Heck if we know! But with this fun game, you can build your own. TenAble is a math skill game and much more. Players must build on the pyramid game board by placing their stones on top of or next to existing stones with a value of +/- 10. You may also make a double match by matching the bottom and adjacent stones at the same time, causing the player to the right to draw an extra stone. Win the game by getting rid of all your stones. It’s fun for the whole family and everyone will learn as they play!
