My brain can't handle robot math. I like the concept though! Maybe some explanation will help. E.x. why they are 4 numbers for 4 slots if only 1 equation is possible with each one.
Thank you for you comment! :) I actually thought of making slots change in amount, depending on the levels (but we just left 4 and 4 because of some UI shenanigans ":>), i can see the point
