This game is actually a lot more fun than you would think. Throw the dice to begin selecting the corresponding colored wooden cylinder blocks. Be careful not to rock the moon and cause the blocks to come tumbling down! Ever changing game...makes for long lasting fun. Teaches gravity, balance, and strategy. You can also variate how you play based on the age of the child. Roll the dice and add blocks for younger children or play the traditional game of removing blocks for older children.
