One person takes on the role of "whacker" and everyone else is a "mole." The moles hide out in their own cubby areas...jumping up sneakily to steal the plastic balls from the middle ring...and hoping not to get whacked. If they fail, moles have to drop back down without any bounty but if they succeed, they can hoard the balls they capture in the nets provided at each mole's station. The mole who has the most balls in the end...wins!
