The game is played from a single-screen top-down maze view. Mr. Do can dig new tunnels through dirt, and a stage is cleared by collecting all cherries. He can also defeat enemies for points and pursue bonus goals. His main weapon is a bouncing ball that travels outward and later returns, meaning he cannot fire again until it comes back. Apples scattered across the field can be dropped to crush enemies and open space. Collecting letters that spell EXTRA triggers a bonus round and awards an extra life. Later rounds increase enemy speed and pressure.

Mr. Do

The clown protagonist controlled by the player, who digs tunnels, gathers cherries, and fights enemies underground.

Red Monster

A standard enemy type that relentlessly chases Mr. Do through the maze.

Alpha Monster

A more dangerous transformed enemy that can pressure the player aggressively through open tunnels.

Plan routes that let you clear multiple cherry groups in one pass instead of backtracking for single items. Always consider your escape path before firing the ball, since you are vulnerable until it returns. Use apples to crush groups of enemies whenever possible for safer clears and better scoring. If monsters close in, dig into untouched soil to create an emergency exit. When bonus letters appear, avoid reckless grabs; secure the area first, then complete EXTRA.

Tips

Apples work best when enemies are lured directly underneath before you drop them.

Tips

Avoid circling too long in open tunnels; digging fresh paths creates more escape options.

Tips

The bouncing ball is especially effective in narrow corridors where enemies line up.

Its mix of digging, attacking, and trap use makes it richer than many maze games of its era.
