hue
A smooth colour gradient arrives shuffled. Put it back in order using nothing but your own colour judgement — there are no numbers, no labels, and no undo worth relying on.
How a round plays
Sort the gradient by eye.
- Tap two swatches to swap their positions.
- Work from the ends inward; the middle is always the hard part.
- The round ends when the ramp is smooth again.
Scoring and fairness
What the grade is measuring.
The ◆ grade. Swaps used against the minimum needed to sort that shuffle.
Hints.Locks one swatch into its correct position. Using one keeps you off the ranked board for that day, so a hint can rescue a round but never buy a rank.
How the result is proved.Replayed move log. Every one of the ten games is verified server-side in one of three ways — a replayed move log, a server-graded answer, or per-guess checks that end in a signed win token — so the leaderboard only counts results the server could reconstruct for itself.
- Verification: Replayed move log
- Puzzle source: Procedural
- Typical round: 2–4 min
Where it comes from
A new one, every night.
Tomorrow's hue already exists. It was generated from a date seed, checked by a solver, and put in a queue that runs weeks ahead of today — so nothing ships the night it was made, and a bad batch never reaches a player.
