Mole Attack is one of the earliest computerized Whac-a-Mole variants. Gameplay should be clear: Moles randomly pop out of several holes (arranged in a 3x3 grid), and you can hit them using the right keyboard key (one for each hole). The sooner you hit the mole's head, the more points you get -- but if you hit the mole's buttocks (yes, them buggers sometimes pop up that way), you lose points. After 60 seconds, the game ends and your score is shown.
