The players form monsters from play-do (using templates) und uses these to race along a track. They roll and move the number rolled, adding 2 when ending on a field with a shamrock symbol. When they roll a hammer, though, another player can use the hammer and smash the monster which then has to be rebuilt and start at the beginning again. The first monster to reach the finish line is the winner.
