Below are some screenshots from my upcoming game, Number 14, which I have submitted to Apple and is waiting for approval.
Number 14 is a dynamic puzzle game where four random numbers between 1 and 9 are generated. You must combine the numbers using addition, subtraction, multiplication, and division so that the result is 14.
Its power comes from its simplicity, where the concept is easy to grasp however some numbers prove to be very challenging :)
I post these numbers as a challenge to solve :
9 9 4 2
I think almost everyone will find these to be most difficult at first (I certainly did :P )
