Description from the publisher: The dice in Bumpi are unique in that they do not roll on the table; they bounce! This is because the dice are actually five-sided objects in which four of the sides are attached to the fifth, and to "roll" the die, you push it down onto the table, flattening all the sides, then let it spring up to roll around. Why are you doing this? Because all players are presented with a task card at the start of each round. Sometimes you want to find an animal, sometimes a color, and often both — and you need to keep rolling until someone finds a solution and wins the card. Whoever collects five cards first wins the game!
