The title character, Mr. Do (a circus clown—except for the original Japanese version of the game, in which he is a snowman), is constantly chased by red dinosaur-like monsters called creeps,[3] and the player loses a life if Mr. Do is caught by one.

A level is complete either when all cherries are removed, all creeps are destroyed, "EXTRA" is spelled, or a diamond is found.

Mr. Do can defeat creeps by hitting them with his bouncing "power ball" or by dropping large apples on them.

Occasionally, the creeps transform briefly into more powerful multicolored monsters that can tunnel through the ground.

As the game progresses, a display at the top of the screen cycles through the letters in the word EXTRA.

Every time the player's score reaches a multiple of 5,000 points, the highlighted letter enters the playfield as an Alphamonster, which can be defeated in the same manner as a creep.

After they have all appeared, the generator will turn into a food item; picking this up scores bonus points, freezes all the creeps, and calls out an Alphamonster (if one is not already on the field) and three large blue monsters.

The creeps stay frozen until the player either defeats all three blue monsters, defeats the Alphamonster (in which case any remaining blue monsters are turned into apples), loses a life, or completes the stage.

Rarely, dropping an apple reveals a diamond which, if collected, completes the level and awards a bonus credit to the player.
