This app is the famous game 7 Boom!
For those of us who do not know this game these are the rules:
~ Each time the number seven appear you should press the "7" button.
~ Each time the
number on the screen can be divided by 7 you also press the "7" button.
If you got it right you move on, if you got it wrong it's game over.
Every time you can restart the game once it is over and choose which screen to go to next.
There are two possibilities to choose:
~ Regular 7Boom means you go from 1 to which ever number you manage to reach without losing the game.
~ Random Number means you get a different number each time to choose weather it is "Boom" or not.
