Game Rules:
This game has 20 levels, each lasting 5 seconds.
Starting with a 1-digit number, each level will display a number with a corresponding number of digits.
You need to memorize the displayed number within the 5-second countdown.
After the countdown ends, an input box will appear where you need to enter the number you memorized and click the submit button.
The game will check if your answer is correct.
At the top of the game, there is a row of 10 cells, each representing a level. A green cell indicates a correct answer, and a red cell indicates an incorrect answer.
After completing all 20 levels, your total score will be displayed.
Scoring: Level 1: 10 points, Level 2: 20 points, Level 10: 100 points, and so on. The score for each level is 10 times the level number, with a total possible score of 1050 points.
A score of 840 points or higher is considered excellent, and the higher your score, the more excellent your memory!
