One AI term per level: the clue is a definition, the answer is vocabulary you should own. One ladder, 105 levels. Solve a term to unlock the next; the climb gets harder as you go. Topics rotate so no two in a row repeat, guesses tighten past level 42, and a boss guards every twenty-first level.

How to play

Lexicon

One AI term per level, four to seven letters. The clue is a definition. Climb the ladder and own the vocabulary.

  1. Step 1

    Start with the clue

    The definition points at one core AI or data-science term. The grid shows you how many letters it has.

  2. Step 2

    Type a guess

    Type anywhere, or tap a cell to move the cursor. Six guesses through level 42, five after that; bosses take one away.

  3. Step 3

    Read the colors

    Green is exact, amber is elsewhere, gray is not used. Guesses 1–6 score 100, 95, 90, 80, 70, 60; 90+ earns three stars and 70+ earns two.
