New puzzle every day
Sort today’s gradient
Each day you get a row of color tiles with the two ends locked. Reorder the middle tiles so the whole row forms one smooth gradient — neighbouring colors as close as possible. Fewer moves is better. Pure visual intuition, zero luck, no language barrier — and the same puzzle for everyone on the planet today.
How HueLine works
- 1
See the chain
A row of color tiles with the two ends locked. The middle tiles are shuffled out of order.
- 2
Sort the gradient
Tap a tile then tap another to swap, or drag. Make every neighbouring pair flow smoothly.
- 3
Solve & share
When every connector is a solid check, you win. Share a spoiler-free result and keep your streak.

Color sorting puzzle
A color sorting puzzle gives you a set of colors out of order and asks you to arrange them so each one flows smoothly into the next — a single, satisfying gradient.

No language barrier
Daily word games are fun but gated by vocabulary. A color puzzle keeps the daily-ritual format while dropping the language barrier entirely.
Read →Colorblind mode
A color game should not lock out the roughly one in twelve people with color vision deficiency. HueLine adds non-color channels so the puzzle is fully solvable by order alone.
Read →Frequently asked questions
- Is it free?
- Yes — completely free and unlimited. No signup, no payment to play the daily puzzle. Everything runs locally in your browser.
- How is the daily puzzle chosen?
- A deterministic algorithm generates the colors from the UTC date, so everyone in the world gets the exact same puzzle each day. It is never produced by an AI model, and no puzzle is ever sent from a server.
- Is my progress uploaded anywhere?
- No. Your moves, streak and stats are stored only in your browser (localStorage). Nothing about your play is sent to a server or stored in any database.
- Can colorblind players play?
- Yes. Turn on Assist for position numbers, per-tile textures and edge glyphs, so the puzzle is fully solvable by order alone without relying on hue.
- How is this different from a word game?
- HueLine is solved purely by arranging colors, so there is no vocabulary and no language barrier. It is an independent puzzle, not affiliated with any word-based daily game.
