About these games
Number Memory
Number Memory presents a digit sequence for a limited time and asks you to enter the same sequence.
How to play
- Watch the digits displayed on the screen.
- When the sequence disappears, enter the digits in the same order and submit your answer.
- A correct answer advances to the next level with a longer sequence. An incorrect answer ends the current run.
- The practice sequence is capped at 30 digits.
Scoring
The result reports the highest level passed in that run. The level corresponds to the number of digits in the sequence for that stage; it is not a percentile or comparison with a reference population.
Limitations
The game uses timed visual presentation and exact digit entry. Screen size, browser timing, input method, and interruptions can affect a run. The score does not diagnose memory conditions or establish general memory capacity.
