SumRush: The Ultimate Mental Math Challenge

Unlock your brain's full potential with SumRush! Improve your calculation speed, focus, and memory by solving additions against the clock. SumRush transforms arithmetic practice into an engaging, high-focus mental workout designed to help you master mental math.

HOW IT WORKS:

Beat the Clock: You have 15 seconds to solve each addition and sharpen your response time.

Multiple Choice: Tap the correct option among 5 possible answers.

Keep Momentum: Answer correctly to progress further and earn extra time.

Continuous Exercise: A wrong answer or a timed-out clock completes your current practice session, ready for your next attempt.

KEY FEATURES:

Adaptive Progress: The difficulty evolves with you. Start with simple 1-digit sums and progress to complex multi-digit calculations as your skills improve.

Anti-Cheat Logic: For advanced exercises, our unique "Unit Lock" system ensures you can't guess by just looking at the last digit. You really have to calculate!

Global Statistics: Compare your performance with users worldwide. Check your percentile and see if your mental math is faster than 90% of the world.

Ad-Free Experience: Focus entirely on your cognitive training with an optional one-time purchase to remove all ads.

Sleek & Clean UI: Enjoy a beautiful, minimalist design with smooth animations and a distraction-free layout.
