Which rule will you hunt?

Each puzzle hides a different rule. These are its first clues; you get up to 8 tests to find it.

How to play

Some objects fit a hidden rule. Others don’t. Can you find it?

  1. A hidden rule splits objects into Yes and No. You start with two of each.
  2. Test up to eight objects to see which side they land on. A Yes or No uses one test; an unclear answer doesn’t.
  3. Guess the rule whenever you’re ready. You can revise it until you solve the puzzle.
