How It Works
- Click Start to begin.
- Memorize the number displayed on screen.
- Type the number when prompted and press Enter or Submit.
- Each level adds one more digit to remember.
- The test ends when you enter the wrong number.
- Your score is the highest level reached.
Tip: Try grouping digits into chunks (e.g., “492” “817” instead of “492817”). This technique, called chunking, can significantly extend your digit span.

These are real attempts in a browser — every device, every connection, first tries included. Published research figures are usually collected on dedicated hardware with practiced participants under controlled conditions, so they typically run higher than what this table shows. Both are useful, and they answer different questions: a score can sit well behind the research figure and still be mid-pack among people actually taking the test here.
