How to Win at Pac-Man: Ghost AI Patterns & Tips

Pac-Man was released by Namco in May 1980. The world-record holder is Billy Mitchell, who achieved the first “perfect game” — 3,333,360 points across 256 levels — in 1999. Most players never finish a single level. Here’s how to bridge the gap, from ‘I keep dying on level 2’ to ‘I finished Pac-Man on the original arcade.’

The ghost AI: meet your enemies

Each of the four ghosts has a distinct chase pattern. Learning their patterns is the difference between casual and serious play.

Blinky (red): direct chaser. Always targets Pac-Man’s current position. Speeds up as more dots are eaten — by level 4 he’s faster than you.

Pinky (pink): ambush. Targets the position 4 tiles ahead of Pac-Man in his current direction. Move predictably and Pinky cuts you off.

Inky (cyan): complex. Uses Blinky’s position as a reference. Mostly behaves erratically; hardest to predict.

Clyde (orange): scatter. Chases Pac-Man when far (>8 tiles); retreats to his corner when close. Unpredictable transitions.

The chase/scatter cycle

Ghosts alternate between two modes: scatter (each ghost heads to its corner; you can chase them safely) and chase (they actively pursue you).

Levels 1-4: scatter is 7 seconds; chase is 20 seconds. Memorize this rhythm. After 27 seconds you can count: 7s safe, 20s threat, 7s safe, 20s threat. By level 5 the timing changes — scatter shortens to 5 seconds.

Power pellets: the right moment

Eating a power pellet (the 4 large dots in the corners) makes ghosts vulnerable for 6-7 seconds (decreasing per level). Don’t eat them randomly — wait until 2-3 ghosts are nearby.

Eaten ghosts give: 1st = 200pts, 2nd = 400, 3rd = 800, 4th = 1600. Eating all 4 = 3000 points = roughly 5% of a perfect game’s score per pellet. Maximize this every time.

The split-screen kill screen

If you reach level 256 (which Billy Mitchell did in his 1999 record), the right half of the screen becomes a garbled mess of letters and numbers because the game’s level counter overflows an 8-bit register.

You can’t finish level 256 because half the maze is unreadable. The official ‘perfect game’ ends there with 3,333,360 points. Anyone playing past level 256 just gets the unwinnable screen.

The Pac-Man tunnel

The horizontal tunnel through the middle of the screen wraps left-to-right. Use it constantly. Ghosts can use it too but they move 50% slower when in the tunnel. Use the speed differential to escape.

Don’t dawdle in the tunnel — there’s nothing in there to eat. But it’s an excellent escape route when cornered.

Pattern memorization

Each level (up to 21) has known optimal patterns. Memorising these turns Pac-Man from a reactive game into a memorised sequence. World-record players use specific patterns for every level.

Common pattern names: ‘pattern of the rights’ (always turn right at intersections), ‘mid-screen camp’ (eat from the middle outward), ‘around the edges’ (clear perimeter first). Learn 2-3; use them as defaults.

Practice

Play our Pacman. Full 28×31 classic maze with proper 4-ghost AI (Blinky chase, Pinky ambush, Inky complex, Clyde scatter). Scatter/chase cycle implemented faithfully.
