Mental Counting

Can you do math in your head under pressure?

Mental Counting turns arithmetic into a fast, addictive chain challenge. Operations appear one by one — 12 + 7, then − 5, then × 3 — and you keep the running total only in your head. At the end, type the final answer. One wrong digit sends you back to the start.

HOW TO PLAY
• Solve each operation as it appears — no writing, no calculator
• Keep the running total in your memory
• Enter the final answer before the timer runs out
• Every round: bigger numbers, more operations, less time

WHY YOU'LL LOVE IT
• Trains mental math speed, accuracy and focus at once
• The chain mechanic makes every single operation count — literally
• Round history to track your progress
• Quick sessions — a daily five-minute brain workout
• Clean, minimal design with zero distractions
