What is Semantris?

Semantris is a word association game powered by AI (machine learning) originally created as a Google game to showcase how language models understand meaning. This version is a faithful, modernized clone a true semantris tetris with AI experience (with the same drop-and-clear feel as semantris blocks) that runs entirely in your browser. Each word that falls is scored in real time against your typed clue using sentence-embedding vectors from a small neural network, so the connections you make are interpreted semantically, not by spelling or keyword matches. It's a fun way to see modern machine learning at work in an everyday browser game.

How to play this AI Game

  1. Watch the words fall. Five colored bubbles drift down the play area, just like blocks in Tetris — that's the "semantris tetris with AI" core loop.
  2. Type a related word or short phrase into the input box. Don't say the word itself describe its meaning, its category, an object that goes with it, or even an emotion it evokes.
  3. Press Enter. The AI computes the semantic similarity between your clue and every word on screen, and the closest match disappears.
  4. Survive. If any word touches the bottom, the game ends. Levels speed up every 500 points.

Tips to beat the original Google Game

🧠

Think in concepts

For guitar try "strings", "rock", or "musician" — the AI rewards conceptual links, not synonyms.

Aim high

Clearing a word higher on the screen scores more. Don't wait for danger — strike fast.

🎯

One clue, many hits

A broad clue like "kitchen" can target several falling words. Pick the clue that matches the most urgent block.

🤖

Trust the AI

This semantris tetris with AI uses MiniLM embeddings. Emotional, abstract, or metaphorical clues all work.

Why this version of the Google Game is different

  • Runs locally: the AI model loads once and stays in your browser cache — no servers, no telemetry.
  • Open and hackable: a single HTML file. Tweak the word list, threshold, or colors.
  • Looks great: animated gradients, glow effects, and color-coded falling words inspired by semantris blocks.
  • Faithful to the original: the same "type a related word" feedback loop that made the original AI game such a hit among online games fans.
  • Plays anywhere: a true browser-first online game — works on desktop, tablet, and phone, no app store detour.

FAQ

Is this the official Semantris from Google?

No. This is an independent recreation of the popular Google game, built to demonstrate browser-side AI. The original was a research demo by Google AI.

How does the AI game decide which word to clear?

It uses a machine learning model (MiniLM) to encode your clue and every falling word into 384-dimensional embeddings, then ranks them by cosine similarity. The highest-scoring word clears if it passes the similarity threshold — pure machine learning, no rule-based dictionary lookups.

Why is it called a "semantris tetris with AI"?

Because words fall like Tetris blocks and the only way to clear them is through semantic understanding — a perfect fusion of arcade pressure and language AI.

Does it work offline?

After the first load, the model is cached. As long as you don't clear site data, you can replay without an internet connection.
