This is a simple but challenging brain training app for those who want to improve their memory. By repeating it once a day for 30 seconds for a week, you can train your memory. The rules are simple. First, quickly memorize the numbers displayed. Then, recall and input the numbers in order. The numbers are not displayed for a long time. Let's use visual memory to quickly memorize the numbers! So, how many numbers can you remember?
