A magic square is a 3x3 square of numbers where all the columns, rows, and diagonals add up to the same value. A parker square is a magic square which only uses square numbers, or x*x. The variables are set up like this: A B C D E F G H I And remember, it's all the variables squared.
You can go into the project and change the "Repeat Process" code to make it pick a random number from 0 to any number. If you find one, post it in the comments! No one has ever found a Parker Square, so there's a prize!
