In Mr. Dig, you're a clown who has to dig tunnels through an underground maze to pick up cherries and kill monsters. They may be killed by dropping apples on them, or hitting them with the title character's "power-ball," which can be thrown at a Mini-Dino. The monster is destroyed if hit by it, though the ball may ricochet wildly if many paths have already been carved out of the board, so this method of destroying them can become unreliable in the later stages of a scene. As the game continues, Mini Dinos move progressively faster, and also start to become Driller Dinos and dig their own paths earlier in the scene, leading to the board becoming steadily more difficult to clear. If, at the end of the game, the player's score is one of the ten highest since power to the machine had last been turned on, (all ranks default to 10,000 pts when machine is turned on) the player gets to post three initials beside his/her high score, ranked in the appropriate position among the top ten.
