When the five unicorns have friends over, it can get quite cramped in the cloud castle. To make room, the differently sized clouds and unicorns must be carefully stacked around the castle. This requires a delicate touch. In the cooperative dice game Unicorn Glitter Luck Cloud Stacking by HABA, children do not compete against each other but work together. They try to cleverly stack the wooden figures to accommodate all the guests in the castle. If they manage to stack the figures correctly and collect all the sparkling cloud crystals on the cloud game board, they win the game together. But beware of the dangerous thundercloud tiles!.
