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 that has turned out to be the sleeper hit of games in Pyramid Arcade.
The Ice Duo set contains 2 trios each of five colors (red, yellow, green, cyan, and purple).
Works by itself or as an expansion for Pyramid Arcade.
Contents: 30 pyramids (6 each of red, yellow, cyan, purple, and green), folding Twin Win board, 10 small Twin Win cards, 2 dice (color die + pyramid die), Ice Duo rules pamphlet, and pyramid overview pamphlet
