A word-discovery game born from a conversation, shipped as a single HTML file.
Overview
Secretword is a browser game that finds real words hidden inside the letters of any text. The player pastes a poem, a song, a quote or a plain paragraph; the app strips away spaces, punctuation and case, lays the remaining letters out as tiles, and shows every dictionary word that can be assembled from them. Words are collected one per text, and once the collection holds two or more words in the same language, the app composes them into a proverb — "Where there is LOVE, there is DREAM."
The entire product is one self-contained HTML file: no framework, no build step, no backend, no external dependencies beyond an optional web font. It runs from GitHub Page.
It supports seven word languages (English, Russian and Spanish first, plus French, German, Italian, Portuguese) with automatic Cyrillic ⇄ Latin transliteration, so a Russian poem can legitimately yield a Spanish word. Translations appear only when the word language differs from the interface language — useful for language learners, invisible to native speakers.
From game to marketing tool
The mechanic works in both directions. The app finds hidden words — which means a copywriter can use it to deliberately plant one. Write a caption, a product description or a campaign line, run it through Hidden Words, and verify that your secret word is discoverable in its letters (and that no unwanted words are hiding there too). The audience gets a puzzle; the brand gets engagement and time-on-content.
I used exactly this workflow for the Dancing Letters project: a secret word was hidden inside the campaign text, and Hidden Words served as both the authoring tool (checking the word was really there) and the reveal mechanic for the audience. The letter-tile interface — hover a word and the tiles it uses light up — turned the reveal into a small visual moment rather than a plain answer.
Scenarios
Other uses of the same pattern: teaser posts where:
followers hunt for the brand name;
newsletter easter eggs;
classroom vocabulary games;
and... woooow (!)
wedding or event invitations with a hidden word for guests.
