How to Play the Counting Game

How Many? is a subitizing test that challenges your brain's ability to quickly estimate quantities. Subitizing is the instant recognition of small numbers without counting - a fundamental cognitive skill used in everyday life.

  1. Tap to start and dots will flash briefly on screen
  2. The dots disappear quickly - you can't count them individually!
  3. Enter your estimate of how many dots you saw
  4. Get points for accurate guesses, with bonuses for exact answers
  5. As you progress, more dots appear and display times shorten

What Makes a Good Score?

Humans can subitize (instantly recognize) up to about 4-5 objects. Beyond that, we use estimation strategies like grouping. The best players develop mental techniques to quickly chunk and estimate larger quantities.

Brain Science: Research shows that subitizing ability is linked to mathematical aptitude. This game exercises the same brain regions used for number sense and arithmetic!
