Mental math
Flash Anzan
Numbers appear one by one in rapid flashes. Hold the running sum in your head — no writing, no calculator.
How to play
Numbers flash on screen
A sequence appears fast — one number at a time. Look closely; they won't wait.
Keep a running total
Add each new number to the previous sum in your head as they flash by.
Enter the total
When the flashing stops, type your answer. No pencil, no second chance.
