Questions
About Mental math ×3
How long does it take?
About 30 seconds, start to finish. Every Move in MiniMove takes 90 seconds or less.
What if I can't do it?
Take your time and count on your fingers if you like: nobody is grading you. “I can't do this” in the app swaps in another Move and stops suggesting it.
How many minutes does it unlock?
Whatever the Move, it opens the app for the window you chose: 5, 15, 30 or 60 minutes of real use (15 by default), capped at twice that on the clock. It also goes into your Bank.
