Tetra Yatzy (Janary of 2013) [available on Amazon] is a game that evolved from the gameSuper Jax. It's sort of a combination of jacks and Yahtzee. The players take turns throwing the 8 tetrahedron shapes up to three times. The uppermost colored ball is used to form combinations that are scored like Yahtzee: 4 and 3, 5 of a kind, and of course all 8 the same color, for a Yatzy!
