This is a typing game that uses only numbers.
Find the grey number from a list of four numbers and enter that number.
When all four numbers are gone, a new number will appear.
The faster you enter the numbers, the higher your score.
If you can’t enter the numbers within the time limit, the game is over.
There are no complicated rules, so this is a game you can enjoy by emptying your mind.
Enjoy it as a way to kill time!
