devilish calc
Equations flash one at a time. Compute each one — but enter the answer from N steps ago.
How to play
- An equation appears. Solve it in your head — don't type yet.
- When the next equation appears, type the answer to the previous one.
- N starts at 1. Every 5 correct answers N increases by 1 (harder!).
- You have 3 lives. A wrong answer costs a life and shows the correct answer.
- The game ends when all lives are lost. Score = (highest N × 100) + correct answers.
Example at N = 1
| You see | You compute | You type |
|---|---|---|
| 3 + 4 | 7 | — warmup |
| 5 + 2 | 7 | 7 |
| 8 - 3 | 5 | 7 |
| 6 + 1 | 7 | 5 |
