A Wordle-inspired word puzzle built as a browser experiment, with daily challenges, custom games, a practice mode, leaderboards and hints. It runs entirely in the browser — no account required to play.
How to play
- Guess the hidden word within the allotted attempts.
- After each guess, every letter is colour-coded: correct letter in the correct position, correct letter in the wrong position, or not in the word at all.
- Use those constraints to narrow the possibilities with each subsequent guess.
- Switch to practice mode to play unlimited rounds, or take the daily challenge that everyone gets the same word for.
Modes
- Daily challenge: one shared puzzle per day, so scores are directly comparable.
- Custom games: generate a puzzle to share with someone specific.
- Practice: unlimited play with no effect on your streak.
- Hints: a nudge when a round stalls, at the cost of a lower score.
Strategy worth knowing
The mathematics of this puzzle is more interesting than it first appears. A strong opening guess is not the word most likely to be correct — it is the word that most evenly splits the remaining possibility space, because that maximises the information each colour pattern returns. In information-theoretic terms you are trying to maximise expected entropy reduction per guess.
That is why openers packed with common letters and distinct vowels outperform clever obscure words: they partition the candidate list more evenly. It is also why, once the field narrows to a handful of candidates that differ by a single letter, deliberately guessing a word you know is wrong can be the optimal move, since it distinguishes between the survivors in one turn rather than burning several attempts guessing them one at a time.
Built as an experiment
The game exists as a front-end engineering exercise alongside the security work on this site: state management, daily seeding so every player receives the same word, persistence of streaks between sessions, and an input model that works equally well on a phone keyboard and a desktop. Like everything else here, the gameplay runs client-side.
If you would rather break things than spell them, try the classic cipher toolkit or the wider security toolkit.
