How to play

  1. Pick a world and a level, or a game mode: daily, a 10-puzzle test, five minutes, or a streak until the first mistake.
  2. The age level sets the starting point and the test difficulty. The daily puzzle is the same for everyone.
  3. Each world has 50 puzzles and a boss challenge every ten. Solving efficiently with no hints earns three stars.
  4. Stars and your current game are saved in the browser on this device.

Questions and answers

Is the Brain score an IQ test?

No. The Brain score is a game score for fun and practice. It is not an IQ score and not a diagnosis.
