I like the concept..
At first I didn't pay attention to the stuff on the right and thought it was up to me to find the patterns that cause a profit.. Then I reloaded my browser and saw the one pattern I thought was good was now bad. That made me sad haha, as i'd spent time making what i thought was an efficient little pattern for it. So i made a smiley face instead.
I wonder how it would go if the good/bad patterns were fixed but unknown to us, so the aim is to create the most efficient layout? And playing with friends will still cause chaos, without the game forcing it. So knowing there's a solution to find might make it more rewarding?
