In Mole Attack, players are given control of a floating hammer and tasked with bashing moles on the head for points. Players are given 60 seconds in which to do this, in a 3 x 3 grid. However, players can lose points if they smack a mole's ass when it pops out of a hole. The timer is extended if the player can reach 150 points.
The hammer is controlled in eight directions with the center of the VIC-20's keyboard: T, Y, U, G, H, J, B, N, and M. Pressing the key will move the hammer to the corresponding hole and attempt to hit any present moles.
