How we mirror it

90 digits per item, about a minute and three-quarters, with 3 as the target about one time in nine. Tap the box or press Space.

Every press and its timing is stored. Pressing on a 3 is a lapse of attention; missing other digits counts too. Built for the long test, where accuracy can be followed over time.

Items are original, versioned, and assigned at random, so a posted answer spoils only one variant.
