24 Puzzle app for iPhone and iPad

24 is a super fun math puzzle game. The objective of the game is to get 24 by using all 4 numbers given to you using any of the operators (+ - x / ).

Example: 11, 1, 3, 5
1) 11+1 = 12
2) 5-3=2
3) 12x2= 24!!
You think its thats easy? Try this: 8, 8, 3, 3

The app features 3 different game modes:

Classic mode:
You start with 90 seconds, have up to 3 undos, and the availability to skip if you get stuck! Every time you get 24, time will be added to the clock and you gain plus 1 combo that is added to your score. Max combo is 5. The catch is, you will lose combo and time if you skip or fail to get 24. If the time reaches zero, you lose.

Practice mode:
For people who just want to just play casually with no time pressure!

Extreme mode:
For people who think classic mode is too easy and need a bigger challenge. You start off with 25 seconds and you get no undo nor skips. Your combo however doubles faster (Max is 10). Every time you get 24, you start back with 25 seconds again.
