Add1

This is a very simple adding game.

How to play:
You have to add 1111 to a randomly generated number between 1000 and 8888.

Examples:
If the number shown is 2345, the correct answer is 3456.
If the number shown is 3989, the correct answer is 5100.

You have 60 seconds to do as many calculations as possible.

From a correct answer you get one point, from an incorrect one you lose one point.

If you are connected to the Game Center when the app starts, you score will be automatically uploaded to the leaderboard.

Additional settings:
If you swipe right, three setting buttons will become visible.
The left one is Leaderboard, where you can check the best results.
The right one is Restart, which you can use to restart your game.
The middle one is for turning the sound effects on and off (when on, there will be
a special sound for correct and incorrect answer and also for a new high score).

The buttons will disappear when you swipe left.
