Description

nr15, a nice little addictive math game tempting you to create 15 out of randomly chosen numbers.

To achieve this you can use any of the following operands in any given order as often as you think might be necessary :

+, adds two numbers.
-, minus subtracts two numbers.
x, multiplies two numbers.
/, divides two numbers.
x2, power multiplies one number by itself.
avg, average value of two numbers.
split, splits numbers into two digits (eg. 37 results in 3 & 7)

When connecting nr15 to Facebook the app will keep track of your fastest times, and offering the opportunity to let you be displayed as the fastest human calculator in the world.

Additionally you can opt to result the equations in 0, 15 or 37.

Brilliant!!!!!!

An awsome game! I think can be the next game what u need to get!!!!

Really needs some more options...

The game could be really entertaining for those who enjoy a little mathematical challenge...but as it stands I feel no incentive to continue playing.

For one...PLEASE add an option to turn off the timed changing of numbers. I don't know if the numbers are randomly generated or if all sets are solvable, but, some are harder to figure out than others and I would like the opportunity to sit and solve them if I please. This alone would be enough to keep me playing...as it stands I am so frustrated when I'm close to a solution and suddenly my number set is changed.

Second, there really needs some other type of scoring system in place. Whether that entails number of sets solved in a certain time, or even just a count of total sets solved in a sitting or just overall, for our own records. The fastest solve time would great to compare with others IF we were all solving the same set of numbers. Since we're not, there needs to be some other incentive to return to the game each time.

I really think these two changes alone make for a 5 star game. Because, the concept and presentation are already awesome. That is the reason I felt the need to review...in hopes that these changes could be made. Thanks.
