This is a simple game where a number is display and you memorize it. The catch is that the number is display for a very short time (it only seems that way). Start from 4 digits and progress up to 30 digits.
1. SHOW - display the number
2. HIDE - hide number if done before time runs out
3. DONE - check your input number
Give it a try.
