"stylize this graphic, I will use it as a board game board, shade the intersections, it has two exits and two goals, each pencil line is a square, in each lane, every third square add a prize symbol and on the next third a penalty symbol, like this in both lanes until reaching the goal, do not add prizes or penalties at the intersections. make it flipchart size in 2D, generate it in PDF for printing, use blue for one lane and red for the other lane."
