The Counter

"0" is an app very useful to develop your logic and to maintain a good mental agility!
How to play: each screen contains a riddle that allows access to the next screen.
Each riddle is related to the number of the page and the next page.
The only thing you need to do is find the number of the next level into the current screen.
But how to do it?... The trick is figuring out how to find this way!

Simple & addictive game.

Enjoy! :-)
