How to Play the Mental Math Sprint

The Mental Math Sprint is a fast, quiz-show style workout built on the math you meet every day: percentages on a discount tag, quick addition at the till, and simple financial sums. Each question gives you four options and one correct answer. After you press Start, a short 3-2-1 countdown gets you ready, then the clock begins. The goal is simple: answer as many as you can, correctly and quickly, before the timer runs out. The game adapts to your level, so it stays interesting whether you are warming up or chasing a personal best.

Step by step

Choose your timer. Pick 30, 60 or 90 seconds from the dropdown. Your choice is saved for next time.
Press Start. A 3-2-1 countdown appears, then the first question arrives and the clock starts ticking.
Pick an option. Click or tap A, B, C, or D. The correct answer lights up green, and a wrong pick turns red while the right one glows green so you learn.
Watch your tier climb. Correct answers and high accuracy unlock harder tiers, which bring new question types into play.
Protect your streak. Every 7 correct answers in a row earns a milestone bonus. A miss resets the streak and costs one point, but never below zero.
Beat your best. Your high score, best streak and best accuracy are saved in your own browser, so a strong run carries over to your next visit.

Difficulty Tiers, Streaks and Your Personal Leaderboard

There is no sign-up and no global ranking, because the best opponent you have is your own last score. Each session saves three numbers in your browser: your highest score, the best streak you have put together in one run, and your best accuracy. Your best accuracy also decides the tier you start at next time, so a strong player walks straight into harder questions.

🏅 Five difficulty tiers

Warmup, Standard, Pro, Elite and Master. Tiers unlock from your score and accuracy during a round, and higher tiers add reverse percentages, multi-step discounts, bill splitting, commission and tax.

🔥 Streaks and bonuses

Base +1 per correct answer, a +1 milestone at every 7-answer streak, plus a tier bonus that grows with difficulty. A wrong answer costs one point but never below zero.

📊 Saved on your device

Best score, best streak and best accuracy live in localStorage. Clearing your browser data will clear them, because nothing is ever sent to a server.

🎉 80% club
