Whether it's a rainy day or game night, these geometrical brain-teasers will lead to hours (and hours) of fun for both you and the little ones. Using 12 polygon pieces, the object is to fill up the space on the board, which varies depending on where the "slider" piece is placed. (Yes, it has some similarities to that 2D game we've all played.) Relatively easy at first, it gets much harder as the playable space gets smaller. (There are 500 challenges in all.) It's tricky enough to give your brain a workout—and pretty enough to leave on the coffee table between problem-solving sessions. Gather your geekiest pals and/or your mathematically-minded kids and let the challenge begin. Made in China. Want to up your game? See Katamino for Two to play this game with others!
