This is a small tool for training memory.At each level, the user clicks and follows the prompts to find the correct number string. The length of this number string will increase as the level increases. If you click on the correct position, only a green box will be displayed. If you click on the wrong position, the software will tell you the correct position, and the correct position will be displayed in green. Only when you click on all the correct positions in one go you successfully pass the level.
