Numbers appear on the grid. The moment you tap number one, the rest vanish — tap them in order from memory. One more number every level.
Most adults stop around 7
A set of numbers appears scattered across the grid. Take as long as you like to look at them — the clock is not running. The moment you tap number one, every other number is hidden, and you have to tap the rest in order from memory. Clear a level and the next one adds another number.
It is named after working-memory experiments at Kyoto University, where young chimpanzees outperformed human adults at this exact task. Most people stop somewhere between seven and nine. Most who do well say they remember the shape the numbers make rather than reading them one by one.

Getting to 9 is sharp, 11 is remarkable and 14 or more is genuinely exceptional. If you are stuck around 7, that is where most adults land.
Most people do better by remembering the shape the numbers make rather than reading them one at a time. You get three lives, and a failed level can be retried.
