7Boom! app for iPhone and iPad

------ What is ------
7Boom (or 7 Boom) is a game that puts to the test logic, mathematical and concentration skills.
It is an ideal pastime for challenging friends and a great exercise to train the mind.

------ How to play ------
The goal is to reach the number 61 within two minutes.

For example, if you choose to play with the number 7, you have to press the button "BOOM!" every time that the displayed number:
- contains the number 7
- is a multiple of 7
- is composed by digits that summed or subtracted are equal to 7
In all other cases "Next" is the right answer.

But beware!! If you push the wrong button, the counter will be halved.

There are three levels: beginner, expert and genius.
Depending on the selected level, the number to reach is higher.

You can play with numbers from 3 to 9.

------ Version ------
This is the full versione of the game, it is possible to play with any number from 3 to 9.

Any comment or advice is welcome :)

Good Luck!
