Hue Sort

For iPhone

A calm daily puzzle about colour

Every board is a gradient that has been shuffled. Swap the tiles back into place until the colours flow from corner to corner again.

Coming soon to the App Store

A new palette every day

One daily puzzle, the same for everyone. Monday starts gentle and Sunday is large and subtle.

Made for people who love colour

Gradients are built in OKLab. Each solve ends with a palette, with hex and OKLCH codes to copy.

Music that grows as you solve

Each palette picks its own key, and the arrangement builds as tiles find their places.

More ways to play

270 hand-tuned levels across seven packs, Endless boards at three difficulties, and Zen.

Thoughtful by design

Hints, unlimited undo, colour labels, VoiceOver, Dynamic Type, Reduce Motion and dark mode.

No ads, no account, no tracking

Hue Sort collects no data. Your progress stays on your device and in your own iCloud.
