Somebody reads out a number. You have to keep hold of it just long enough to use it.
A number appears, then disappears, and you tap it back in. Each one you get right, the next is a digit longer. Halfway through, you’ll be asked to give them back the other way round — last digit first.
The shortest game of the week — about two minutes.
Read it, then hold on to it.
Tap it back in.
Now the other way round.
Same idea, but this time tap the number in backwards — last digit first, first digit last. It’s a good deal harder, so it starts short again.
