Sixteen terms, four hidden connections, one trap per level. One ladder, one hundred levels. Clear a level to unlock the next; the climb gets harder as you go. Topics rotate so no two in a row repeat, and a boss guards every twentieth level.

How to play

Scroll to see all 3 steps

  1. Step 1

    Climb the ladder

    One hundred levels, harder as you climb. Topics rotate so no two in a row repeat, and a boss with a tighter mistake budget guards every twentieth level.

  2. Step 2

    Select four, submit

    “One away…” means three of your four belong together. Run out of mistakes and the level ends; a retry costs nothing.

  3. Step 3

    Earn the stars

    Start at 100 points. Each wrong combination costs 12. A clear at 90+ earns three stars; 70+ earns two; any lower clear earns one.
