Thanks for playing. So the rule with shpaes is that higher number corner means higher value shape (this value only matter when betting). for example if npc bets 4 squares and you can't bet 5 sqaure, you can go to a higher value shape that is pentagon and bet 1 pentagon. anything square or below you will have to bet 5 numbers, but if you select higher value shape you can bet in lower numbers. Hope this makes it clear. <3
