Most squares of random three-digit numbers (101-999) recalled and typed correctly from memory in 30 seconds

How do you break it?

• The software draws a three-digit number between 101 and 999 each round. Recall its square from memory and type the answer.
• The timer starts when the first number is drawn and runs continuously for 30 seconds.
• A correct answer counts only if submitted before 30 seconds expire. An answer submitted at zero or later does not count. One wrong answer ends the attempt.
• No calculator, squares table, help from another person or other aids. The continuous screen recording must show the numbers, answers and timer.
• The tool score is not a verified record. Submit the screen recording to Herzl, an AI judge, through the attempt form. Herzl reaches a reasoned verdict; unclear cases go to a human.
