Whac-A-Mole is a popular arcade redemption game.
A typical Whac-A-Mole machine consists of five holes on its top and a large, black mallet. Each hole contains a single mole. Once the game starts, the moles will begin to pop up from their holes at random. The object of the game is to force the individual moles back into their holes by hitting them directly on the head with the mallet, thereby adding to the player's score. The quicker this is done the higher the final score will be.
This is supposed to be a game, not real life.
