devilish calc

Equations flash one at a time. Compute each one — but enter the answer from N steps ago.

How to play

  1. An equation appears. Solve it in your head — don't type yet.
  2. When the next equation appears, type the answer to the previous one.
  3. N starts at 1. Every 5 correct answers N increases by 1 (harder!).
  4. You have 3 lives. A wrong answer costs a life and shows the correct answer.
  5. The game ends when all lives are lost. Score = (highest N × 100) + correct answers.
