Frequently Asked Questions
What is Huedle?+
Huedle is a free daily color puzzle game with two modes: Gradient, where you rebuild a shuffled color gradient by swapping tiles, and Hex, where you guess a mystery color using hue, saturation and lightness sliders within six tries.
How do I play Huedle?+
Pick a mode — Gradient or Hex. In Gradient, click two tiles to swap them until the gradient flows smoothly again. In Hex, adjust the sliders to match the mystery color and submit up to six guesses. Each guess tells you how close you are.
When does the daily Huedle update?+
A new puzzle is generated at midnight UTC every day and is the same for every player in the world. You can check today's puzzle number and date on any game page.
Is Huedle free?+
Yes. Huedle is completely free to play in your browser, with no account and no download. Your streak and scores are saved privately on your own device.
How is the Gradient score calculated?+
After you submit, every tile is compared to its ideal position using the CIEDE2000 color-difference formula. The average difference is converted to a score from 0 to 100 — a perfectly restored gradient scores 100.
How is the Hex score calculated?+
Each guess is scored by how close your color is to the target, measured with the CIEDE2000 formula. Your final score comes from your closest guess, so an earlier lucky hit counts just as much.
Can I play past Huedle puzzles?+
Yes. The archive lists every past daily puzzle — open any date to replay that day's Gradient or Hex. Practice mode also lets you play unlimited random puzzles.
Do I need to know hex codes to play?+
No. You never type a hex code. In Huedle Hex you move three sliders — hue, saturation, lightness — and judge the color with your eyes. The game name is a nod to hex color codes, not a typing test.
