How to play

Collect yellow signal cells without striking the circuit wall or your own trail.

02

Controls

Arrow keys or WASD. On touch screens, use the directional pad below the board.

03

Rules & result

Each cell adds 10 points and extends the pulse. The transmission ends on contact.

04

Scoring tip

Plan wide turns, preserve open lanes, and avoid sealing the center too early.

How Pulse Snake works

A small real-time simulation updates movement, collision, and score on every animation frame. The run safely pauses when the page is hidden. Restart creates a clean state without reloading the page, and optional records remain on this device.

Accessibility and devices

The game uses visible text feedback in addition to color. Controls are keyboard-focusable, touch targets are at least 44 pixels, and motion is reduced when your system requests it.
