The twenty-seven steps

The path goes from the smallest numbers to the largest. Each range is taken three times — read, written, then both mixed — and three reviews take up everything that came before. The hundreds alone (C, D, M and their multiples) have a range of their own, before being mixed with the tens and units.

Each step has its review sheet (the ⓘ button): the numbers it covers and how they are written, to read before playing.

A step can be replayed as often as you like: the stars keep the best result, they are never lost. One to three stars depending on pace — 8, 14 then 20 correct answers per minute.
