📖 How to Play

  1. 1 A number will flash on screen for a brief period.
  2. 2 When the input box appears, type the exact number sequence and press Submit.
  3. 3 Each correct sequence adds one additional digit in the subsequent round.

⚖️ Game Rules

  • ✔ One strike policy: One mistake ends the test and calculates your maximum digit span capacity.
  • ✔ No pen, paper, or external recording devices allowed for authentic cognitive benchmarking.

🏆 Understanding Your Score & Benchmarks

Average human digit span is 7 digits (George Miller’s magical number 7±2).

11+ Digits Eidetic / Memory Athlete
Extraordinary chunking and phonological loop capacity.
9 – 10 Digits Superior Memory
Significantly above average working memory.
7 – 8 Digits Normal / Average
Standard human cognitive capacity.
5 – 6 Digits Slightly Below Average
Vulnerable to distraction or lack of rehearsal.
< 5 Digits Distracted
Substantial memory overload.

⚡ Pro Tips to Boost Your Score

  • 💡 Group digits into chunks of 3 or 4 (e.g. 5-8-2-9-1 becomes 582 and 91, similar to phone numbers).
  • 💡 Repeat the numbers rhythmically in your head using inner speech (phonological rehearsal).

💡 Frequently Asked Questions
