Hexcodle

How to play

1. 01

   Know the code

   Hex codes come in three pairs, RRGGBB, for how much red, green and blue is in a colour.

2. 02

   Type a guess

   Enter any valid hex code (0–9, A–F). A colour you know is a good start: 0000FF is bright blue, FFFF00 is bright yellow.

3. 03

   Follow the arrows

   Each digit gets a check mark when it's right, or an arrow toward the target: one arrow within 1 or 2 steps, two arrows when it's 3 or more away.

4. 04

   Solve in five

   Find the code in five tries or fewer, then share your result.

Good to know

• A score too. Besides your tries, you get a percentage for how close your guesses were and how few you needed.
• Harder settings. Hard and expert difficulties give less help, and RGB mode turns each pair into a 0–255 value.
• More to play. There's also Hexcodle Mini, an archive of past days and custom games.
