A game of skill and dexterity for any number of players or amusement for a person alone.
Place the hemisphere flat side up so that it wobbles. Take it in turns to throw the die and place one block on the hemisphere and then one block on another to form a tower. The colour indicated by the throw of the die is the colour of the block that must be placed in that turn. The player in whose turn the tower collapes loses the round.
