Recallc
Numbers go in — will they come out?
Recallc is a sharp short-term memory drill: a string of digits flashes up, then you type it back in the right order. Quick, focused reps for the everyday memory you lean on for phone numbers, codes and instructions.
How to play
- Watch a sequence of digits appear.
- It vanishes — hold it in mind.
- Type the digits back in the exact order.
