Can you read a number that's flashed on the screen for only a few milliseconds? This game will start with a few hundred milliseconds and reduce the duration until you can no longer enter the number correctly. You can select the number of digits; 3 is very easy; 5 is very hard. Practice and notice the improvement. Find the time of day when our visual acuity and ability to concentrate is highest. Test your skill against friends and family; it will be rewarding activity for ages 8 and up. This initial version is free, but not very slick; if it generates sufficient interest, I will add many features (such as keeping statistics on scores and for different players) and charge a few dollars.
