Ice Duo is actually two complete games in one box: Ice Dice and Twin Win. Ice Dice is a press-your-luck game that was specifically designed to be an introductory game for the pyramids. It features a special pair of dice designed for this game but useful now for many others. Twin Win is a quick little hidden goal game with a bit of bluffing and a bit of strategy. As a Pyramid Arcade expansion, two sets of Nomids will bring a Pyramid Arcade set up to the five trios needed for several popular games, in five of the ten colors.
