How to play
- Press Start — a number appears on screen for a few seconds.
- Memorise it before it disappears.
- Type the number from memory and submit.
- Get it right to advance — each level adds one more digit. One wrong answer ends the game.
Strategy & tips
- Chunk the digits into small groups (like a phone number) instead of one long string.
- Say the number to yourself as it shows — hearing it helps you hold it.
- Find a rhythm or pattern in the digits to make them stick.
- Do not second-guess; your first recall is usually the most accurate.
- Stay relaxed — stress shrinks your working memory more than the extra digit does.
