How to play
A secret English word is chosen. Every word is a point in a 100-dimensional meaning space (GloVe 6B: Wikipedia 2014 + Gigaword 5). Your guess is an equation: words added and subtracted.
The game evaluates the expression and scores the cosine similarity between your combined vector and the secret word. Higher is closer. Parentheses matter: a group in ( ) is evaluated first, then compressed into a single unit vector — one concept that competes with equal weight against the terms around it. So (king−queen)+jack ≠ (king+jack)−queen.
Each guess shows ≈ nearest words: what your equation actually equals. Probe with single words, then steer with arithmetic. You win when the secret word appears in your expression. Vocabulary: the 25,000 most common lowercase English words.
