Try to touch numbers, letters, Roman numbers or Greek letters in the correct order.
It is a very funny game that can be also played by kids and toddlers and will improves your concentration.
The rule is very simple. You have to order numbers from 1 to 25 or 1 to 100 or order letters from a to z.
Just respond quick and try to beat your best time.
Roman letters or Greek letters are options to be played.
So it is not only how quick you tap or your speed or reflexes. Some general knowledge will for sure help.
This will improves your peripheral vision and observation skills.
You have also the option to select the size of the table. Bigger tables will be more difficult.
Enjoy the game!
