How it works
1
A problem appears: easy, medium or hard, your choice.
2
Solve a chain of three in a row.
3
A wrong answer brings a fresh problem.
Why it wakes you
Mental arithmetic wakes the thinking part of your brain, which is the last part to come online.
Good to know
Math is one of the three backup dares, and it is on the Free plan.
Cannot do it one morning? Switch to a backup dare: Math, Type a Phrase or Shake. You still owe a dare, just a different one. Walk away half-way and the alarm rings again in 15 to 20 seconds.
