Huedle Hex: Guess the Hex Colour Code

Rule checks

Green, yellow, grey

A guess is six characters, each 0–9 or A–F, which is the usual #RRGGBB form. After you submit, each digit is marked on its own:

• Green — that digit is correct and it is in the correct slot.
• Yellow — that digit appears somewhere else in the code.
• Grey — that digit is absent.

The live page on 9 Nov 2026 showed eight rows and six columns. The official thumbnail crops tighter and can look like five rows. I use the live page for the row count, and I mention the thumbnail so the two pictures do not get averaged into "about six".

Why your puzzle is not mine

The target is generated for the player, not from the calendar. The person who posted the game on Reddit wrote that the answer is random and is not the same for everyone. A reload during the 9 Nov 2026 check produced a new target. There is no puzzle number, no archive of shared boards, and no single code to publish for "today".

Some search summaries still call this a daily puzzle. That description matches the tile game and Hexcodle, not this page. I leave the disagreement in place: the author and the live reload say random; a summary that says daily is describing a different product.

Sharing a result uses a line like Huedle #a98af2 plus a row of marks. That line includes the colour you were given, so a shared card is your puzzle, not the world's puzzle.

How to read a hex pair

Each pair is one channel. RR is red, GG is green, BB is blue. 00 is the channel off, FF is the channel full. A pair is a byte: 16 times the first digit plus the second. A single digit does not tell you the channel brightness without its position.

A green digit tells you to keep that character in that slot. A yellow mark suggests another position for that digit; keep any green positions fixed as you interpret later feedback. Eight rows is the whole budget on the live UI. There is no hint button on this version.

Who built it, and what it is not

The domain huedle.com was registered on 4 Mar 2022. The public Reddit post in r/web_design is dated 8 Mar 2022. Ionata Digital built it as a WebAssembly experiment; the site serves a wasm build. The page has no viewport meta tag, so the layout is desktop-first. I found no ad script in the initial HTML that day.

Hexcodle is the daily cousin: a shared hex puzzle with an archive. On 9 Nov 2026 Hexcodle was on puzzle #1186. It is a different site, hexcodle.com, and it belongs on the games like Huedle table, not in this version's daily column. The tile rules live on how to play. The full set of names is on versions.

The page publishes no mobile layout promise. If the keyboard is cut off, that matches the missing viewport tag, not a broken daily seed. Price is free. Modes on the page are a single game, Share, and Play Again.
