How to play
Watch the digits as they flash one at a time. When the recall field appears, enter every digit in the same order and submit.
A correct recall makes the next sequence one digit longer. An incorrect recall makes it one digit shorter.
Recall is forward-only. The game ends after three consecutive incorrect recalls.
Use the number keys or on-screen keypad, then press Enter or select Submit.
In the real assessment
The real assessment does not tell you whether a recall was right. This practice version flashes ✓ or ✕ after each submission so you can learn.
