About Upword
Upword is a free word-guessing game for the browser. A hidden word is drawn in pixels, and at first you see only its bottom row; each wrong guess reveals another layer, so you try to read the word from its shape before too much of it shows. You get three wrong guesses per puzzle, a hint gives the word's length, and you can reveal a row yourself or start a new puzzle. Settings change the reveal direction (bottom up, top down or from the ends to the centre), the letter case and the puzzle font (a pixel font, Times New Roman or Comic Sans). With an optional username, kept in your browser, you earn XP, level up and appear on global leaderboards. The developer, posting on Reddit as u/machinegun2187, describes it as similar to Wordle and says it was made almost entirely with Codex.
How it was built
Partially verifiedThe developer's post on r/codex (22 Sep 2026, UTC) is titled “Made a browser-based game almost entirely using Codex”. The post itself only links the game and describes it; it does not say which model ran in Codex or how the developer worked with it.
Made almost entirely with Codex, per the developer. The game is plain JavaScript in ES modules drawing the words on a canvas, with Supabase for usernames, XP and the leaderboards; it calls no AI services.

“Made a browser-based game almost entirely using Codex”Verification notes: AI use from the title of the developer's post on r/codex by u/machinegun2187 (22 Sep 2026, 16:11 UTC), read from the Arctic Shift Reddit archive on 7 Nov 2026; the post links the game and describes it as similar to Wordle, with a layer of the word's pixels revealed after each wrong guess. “Almost entirely” is not a percentage, so no AI code share is recorded. Gameplay, settings and the Supabase leaderboard from the game page and its script, read on 7 Nov 2026; the script calls no AI services. Developer: the game is hosted on the GitHub Pages site of the account adityabhandari781, which the developer links; no page we could open states a full name (GitHub itself was not reachable from our environment), so the account name is used. The Wordle comparison is the developer's; the game does not use the Wordle name. No release date is given; the game was public by 22 Sep 2026. Team size is not stated. The game was not played.
