Less Than 8: free puzzle app for iphone

 

The object in Less Than 8 is to place the 16 numbers in the grid so that each row & column adds to exactly 8.


The 16 numbers are given to you randomly. So there's a little guessing that must be made.  I only played this 3 or 4 times and did not succeed.  On my last attempt, I got 3 columns and 3 rows to be 8 and 1 column and row to be 7. Which means I played it perfectly, but still could not solve it.


I think there's something more to this puzzle app, but I don't have the patience for it. Nevertheless, the concept has potential.
