Challenge — Timed Practice

Race the clock, manage your lives, and push your mental math under pressure. Challenge mode is perfect for building speed and focus with immediate feedback.

How Challenge works

You have a fixed timer and 3 lives. Answer as many questions as you can before time runs out or you lose all lives.

  • Choose a difficulty (Easy / Medium / Hard) above.
  • Each mistake costs a life; three mistakes end the run.
  • Questions are graded instantly; your score increases with each correct answer.

Timer, lives, and scoring

  • Timer: The countdown starts after a short 3-2-1.
  • Lives: Incorrect answers remove a life. You have 3 total.
  • Score: +1 per correct answer. Beat your best per difficulty.
  • Finish: The session ends when the timer hits 0 or you lose all lives.

Difficulty levels

  • Easy: foundational questions.
  • Medium: moderate difficulty.
  • Hard: harder questions, higher focus required.

Your best score is saved per difficulty when logged in.

Leaderboard & review

  • Open the Leaderboard to compare scores globally.
  • Use Review Mistakes at the end to see the correct answers.
  • Replay immediately to improve your best score.

Tips for speed

  • Scan options before fully solving, eliminate obvious outliers.
  • Estimate when exact arithmetic is slow; confirm with a quick check.
  • Skip mental dead-ends fast, momentum matters under time.

Why use Challenge?

Challenge mode sharpens speed, attention, and decision-making under a light time pressure. It complements Practice (which focuses on learning) and Ranked (which tracks your rating). Use Challenge to build quick intuition, then review mistakes to convert speed into durable skill.
