Dot Muncher Tips: Clear 12 Mazes Without Losing a Life (2026)

1. Read the build before you read the legend

Arcade lore says the red one chases you, the pink one ambushes ahead of you, the cyan one flanks, the orange one wanders off when you leave him alone. This build has none of that. All four ghosts run the same algorithm: a breadth-first path to the tile you are currently standing on. Sample after sample, all four paths ended on your tile.

Two consequences. There is no "safe ghost" to bait and no character pattern worth memorising — what there is, is four hunters that all converge on where you are now, each treating the other three as walls, and each moving at half your speed (1 px per frame against your 2).

The second consequence is that the mazes do not get faster. Maze 1 and maze 12 run at exactly the same speed, so the arcade idea of "surviving the later levels" does not apply here. What changes is the shape of the corridors: 12 mazes, 300 to 328 dots each, 3,772 dots in a full run, 4 pellets each. Difficulty in this build is geometry, not speed.

2. Turns land on tile centres, and a wall ignores your key

The muncher only changes direction when it is centred on a tile, and only if the tile in the new direction is open. A key pressed into a wall is accepted and then discarded — the muncher keeps going the old way. Measured: parked against the left wall with a wall tile to the west, the left arrow changed nothing.

Since a tile is 20 px and the muncher moves 2 px per frame, you cross one tile every 10 frames, about 167 ms. So a turn is never instant: press it roughly half a tile early, before the mouth reaches the corner, and only one turn is buffered at a time. Queuing two directions into a tight corner loses the second one.

This is also why you cannot pivot on the spot. In a dead end, the only way out is to arrive already pointing out of it.

3. The edges are joined: one or two through-rows per maze

The maze's left and right edges are connected. Walking off the left edge brings you back in on the right at the same height — measured: from tile 0 the muncher re-entered at tile 27. Not every row is open on both sides, so this is a corridor, not a shortcut across the board:

• Maze 1 opens on row 15 only.
• Mazes 2, 4, 6, 8 and 12 have two through-rows (for example rows 9 and 18 in maze 2).
• Mazes 3, 5, 7, 9, 10 and 11 have one.

Treat those rows as your escape lane. When a ghost cuts off the short way back, run the full width instead of turning into a dead end — you are faster than the ghosts, and the far edge is closer than it looks. The same rows are also where the pellets sit, so the lane that saves your life is the lane that feeds you.

4. The pellets: four per maze, 7.5 seconds of blue

Every maze carries exactly four power pellets: two in the left corridor and two in the right, and their rows change from maze to maze — 10 different layouts across the 12 mazes. In maze 1 they sit on rows 4 and 24 of both side corridors; in maze 2 they drop to rows 3 and 28.

Eating one flips all four ghosts blue for 450 frames, about 7.5 seconds of real play (measured: 7.57 s until they turned back). A blue ghost you touch is eaten for 10 points, and the eaten ghost walks home to the house before it is dangerous again.

The blue is not solid: in the last stretch of the timer the ghosts start flashing, which is your cue to be somewhere else. The 7.5 seconds are a budget, not a licence. Spend a pellet when a ghost is already close, so the chase costs you nothing, and use the flashing as the signal to leave rather than to start a new kill.

5. A death is cheap: the dots stay eaten

When a ghost catches you, the muncher and the ghosts reset — and the dots you already ate stay eaten. Measured: 298 dots on the floor, three eaten, then a death, and the floor still held 295 dots. Your progress in a maze survives; you lose position and time, nothing else.

With 5 lives, you can afford a couple of mistakes per maze. What you cannot afford is panic: after a respawn, the fastest route to safety is the through-row from section 3, and the pellets you already used are gone for that maze, so re-plan around the dots that are still on the floor.

6. Score math: 1 point per dot, 10 per ghost, 50 per life

The score is deliberately simple. A dot is worth 1 point, a blue ghost you eat is worth 10, and the end screen adds 50 for every life still in hand. A full run of 3,772 dots is worth 3,772 points before any ghosts; four lives left is another 200.

That arithmetic decides what to chase. A ghost is worth 10 points and a life is worth 50, so eating a blue ghost is only worth it when it is free — when it is already on top of you, or when the detour costs you nothing. Trading a life for 10 points is a bad trade five times over, and the end screen is where that shows up.

7. Plan the run, and the mistakes that waste it

Every maze has the same speed, so the run is a reading exercise. Mazes 3 and 7 are the biggest at 328 dots, mazes 2, 6 and 10 the smallest at 308. The pellets move, the through-rows move, and the side corridors change shape; the dots never do.

Five habits cover most of it:

• Turn early. A key into a wall is discarded, so commit a half-tile before the corner.
• Know your through-row. One or two rows per maze connect the edges; learn them and use them to escape.
• Spend pellets on contact. 7.5 seconds of blue is a window for repositioning, not a hunting trip.
• Do not circle. All four ghosts path to your tile, so looping in a small circle pulls four of them onto you; distance and walls are what work.
• Do not expect to cross the middle. The 20-cell house blocks the centre row; use the top or bottom route to change sides.

FAQ

How is this different from the rules on the game page?

The game page covers operation: arrow keys to steer, Space to pause and resume, swipe on touch screens (12 px threshold, dominant axis), and the goal of clearing every dot. This guide covers what to do with that: how the ghosts actually hunt, when a turn is accepted, which rows connect the edges, how long the blue lasts, and what a death does and does not cost you.

Do the ghosts behave like the arcade originals?

No. There are four ghosts and they all chase your current tile with the same algorithm; there is no ambush, no flanking and no random wanderer. When they are blue they pick a random legal step instead, and once eaten they walk back to the house. Expect four hunters at half your speed, not four personalities.

Why do I keep dying even though I turned the corner?

Two reasons, both measured. A turn is only taken at a tile centre and only if the neighbouring tile is open, so a late turn into a wall is ignored and you keep travelling straight into it. And circling does not shake a ghost here: all four re-path to your tile, so a loop simply hands all four of them your position. Turn early and leave the area.

What happens to my dots when I get caught?

They stay eaten. A death resets the muncher and the ghosts, not the maze floor. With 5 lives per run, a death costs position and time, and your dot progress in that maze survives.

How many mazes are there, and do they get harder?

Twelve, and they do not get faster — the muncher stays at 2 px per frame and the ghosts at 1 px per frame in every maze. They get more tangled: the dot counts run from 300 to 328, the pellets sit on different rows each time, and the through-rows that connect the left and right edges change from maze to maze.
