Hexle

Wordle's rulebook applied to a hex code. Six characters, six tries, and tiles that come back green, yellow or grey. What makes it odd, and interesting, is that the target here is a colour rather than a word, so the game hands you a hint most colour puzzles would never allow: the #Hexle heading at the top of the page is drawn in the exact colour you are hunting.

1. Look at the #Hexle title. That is the day's colour, rendered in it.
2. Type six characters from the A-F and 0-9 pad and press Enter.

Hexle is the purest crossover between word-game reflexes and colour work: you already know how to read green, yellow and grey, so nothing has to be learned, but the thing you are decoding is a colour and the grid gives you no perceptual help at all. The saving grace is the hint built into the page, which turns the game into a two-step problem, first estimate the colour by eye from the heading, then use the Wordle logic to nail the exact characters. It is small, free, has no account and no ads, and stays comfortably inside a coffee break.

Positional, not perceptual. The tiles use Wordle's three colours on the characters of the code, so a yellow does not mean your colour was warm or cold, it means that digit is in the answer at another position. That distinction matters more than it sounds: hex codes repeat characters constantly, and a yellow B tells you nothing about which of the six slots it belongs to. There is no distance readout and no warmer or colder signal anywhere.

Core play

A single default puzzle: you type a six-character hexadecimal code (characters A-F and 0-9) and have six guesses. Tiles use Wordle-style green/yellow/grey feedback on each character, and the page’s #Hexle heading is rendered in the exact target colour as an additional hint. The site and repository show no alternate game modes.

• Because feedback is positional, spend the opening guess on coverage rather than on a colour you believe in. ABCDEF and 012345 between them test every character in the alphabet, which is a luxury Wordle players never get.
• Remember the shape of a hex code. The first character of each pair carries most of the weight, so a green in slot 1, 3 or 5 pins down far more of the colour than a green in slot 2, 4 or 6.
