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 — the same kind of challenge as holding a phone number or door code in mind.
How to play
- Watch a sequence of digits appear.
- It vanishes — hold it in mind.
- Type the digits back in the exact order.
- Sequences get longer and faster as you succeed.
