How Four Link works

The board state and win lines are evaluated locally after every turn, providing immediate text and visual results. 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.
