RiddleCube is a party-style puzzle game for 1-4 players, although more can be added if you purchase a second set. Intended for ages 8+, the game features the titular “RiddleCube”-- a skeletal cube made from plastic tubes and elastic cords to allow it to be bent or twisted in numerous ways. The game proceeds by having one player flip over a challenge card and start a 60-second sand timer. Players then race to contort their cubes into the shape shown or mentioned in the card; for example, the card might show a 2D image of a triangle, or it might say “bracelet”, and the first person to create a triangle, or a shape that might serve as a bracelet, respectively, keeps the card. The first player with 5 cards wins! The focus on playing as a group serves as an excellent way to keep the game fun even for older players. RiddleCube tests the ability of players to think on the fly and quickly modify their 3D object to fulfill the constraints offered by each card.
