Redline

Everyone races through maths puzzles at once. Correct answers build a score multiplier; mistakes break your streak.

How a round works

  1. Everyone starts their own maths race at the same time.
  2. Tap the correct answer and keep solving to build your multiplier.
  3. 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.
