Redline
Everyone races through maths puzzles at once. Correct answers build a score multiplier; mistakes break your streak.
How a round works
- Everyone starts their own maths race at the same time.
- Tap the correct answer and keep solving to build your multiplier.
- Watch the clock and your streak. A mistake or difficulty switch causes a two-second stall and resets the multiplier.
Scoring & winning
Correct answers earn points with a multiplier up to ×5. Hard puzzles pay double. Most points wins.
