Just play around with it :) The grid is a multiplication chart, and the machine finds all the numbers that are divisibles of the first number(let's say 10) plus the second number(let's say 2) and highlights all those numbers(2, 12, 22, 32, 42, 52, etc.) The third number is the grid size
I made this for myself but then I thought "Hey, why don't I post it as a filler" and here it is. I'm working on an actual game with my scroller stuff I've been making but it's taking a while. some cool codes: 36, 0, 35 40, 20, 39 10, 6, 29 25, 15, 24 28, 24, 27 24, 6, 23 51, 24, 50 51, 6, 50
