Google's word-association experiment proved a language model could be a playmate — in 2018, and then it stopped. Here's where that idea went next.
Play the Modern One Free →Quick answer: Semantris — Google's AI word-association game — launched in 2018 and is still playable at research.google.com/semantris (we checked on July 16, 2026), but it's an unmaintained experiment: two modes, no daily puzzle, no updates. The best modern replacements: Yapword if you want a generative AI that actually plays against you (free daily game, iPhone/iPad app rated 5.0 as of July 2026); Semantle or Contexto for pure semantic guessing; Converge for the word-association mechanic itself. All 7 picks below were verified live in July 2026.
Semantris launched in 2018 as a Google AI experiment — still hosted on research.google.com, with a companion page on Experiments with Google. Its own description is admirably plain: a word association game powered by machine learning. You typed a clue; an embedding-based natural-language model ranked every word on screen by how strongly it associated with your clue; the best match cleared. That was the whole trick, and in 2018 it felt like sorcery.
It shipped with two modes. Arcade was the timed one — words scroll up the screen and you fire associations as fast as you can type them. Blocks was the untimed one — colored word-blocks pile up Tetris-style and you clear them by typing related words. No accounts, no streaks, no daily word: it was a research demo wearing a game costume, and it never became more than that.
That's the gap this page fills. If you're searching for games like Semantris, you probably want one of two things it pioneered: playing with a language AI, or scoring words by meaning instead of spelling. The seven games below cover both — and the AI side has gotten dramatically better since 2018, because the models went from silently ranking words to talking back.
Semantris' model ranked your words in silence. Yapword's talks back. Yapoleon — a self-crowned AI emperor powered by Google Gemini — knows the hidden word, watches every guess as it lands, grants hints on request (a text hint, an emoji clue, or a suggested guess), reacts in real time, and closes each game with a roast built from your actual board. The structure is daily like Wordle rather than arcade like Semantris: three 5-letter words per day, one per difficulty tier (Training Wheels, Fair Fight, and Ego Death), the same word for every player at that tier, rolling over at midnight US Eastern. There are also themed games on any topic (4–7 letters) and head-to-head challenge duels with friends. The daily puzzle is free forever with no account, on the web or in the free iOS app for iPhone and iPad — rated 5.0 on the App Store as of July 2026, with Android in the works. (Disclosure: Yapword is our game.)
Play Yapword free →The direct heir to Semantris' word-embedding trick, pointed at a single hidden word. Each guess gets a similarity score from a Word2vec embedding model — no letters, no positions, just how close your word's meaning is to the target's. It's famously brutal: "cold" and "ice" can score further apart than you'd ever expect. If Semantris' Blocks mode was your speed, Semantle is its patient, merciless cousin. We rank its whole family tree in games like Semantle, and it earns a spot on our hardest word games list too.
Play Semantle →Same idea as Semantle, kinder interface: every guess gets a rank — you're told your word is the 2,431st closest to the secret word, or the 12th — so you always know whether you're circling or lost. Free on the web with a new word daily. If Semantris taught you to think in associations, Contexto is the daily habit that keeps the muscle warm. More like it in games like Contexto.
Play Contexto →The closest match on this list to Semantris' actual mechanic. Converge is a daily puzzle it describes as a quiet collaboration between you and the AI: you each say a word, then keep taking turns, each trying to converge on the same word one round at a time. It's word association as a duet instead of a shooting gallery — slower and gentler than Semantris' Arcade mode, but built on the same pleasure of meeting a machine halfway on meaning.
Play Converge →A free Semantle-style daily — guess the word by semantic similarity — with one transformative addition: it plots every guess on a 2-D map of the embedding space, so you can literally watch yourself orbit the target instead of squinting at a bare number. Of everything here, it's the game that most looks like what Semantris let you feel: the shape of a language model's idea of meaning.
Play Pimantle →If part of the appeal was "Google made a playful AI demo," this is the sibling that survived from the same experiments program: you doodle, and a neural network shouts guesses at what you're drawing, 20 seconds a round. It's sketching rather than typing, but the arcade pulse — you versus a model, against the clock — is pure Semantris. Still online as of July 2026. For more games where an AI does the guessing, see our AI guessing game guide.
Play Quick, Draw! →Neal Agarwal's viral toy: start with four elements and combine words while a large language model invents every new result on the fly. There's no guessing and no score — it's the least Semantris-shaped game here — but it delivers the other half of the original's magic: poking a language model to see what it thinks words mean, and being surprised. Play in the browser or via the official iOS app.
