Honestly will say you might want to buff/nerf somethings.
Unless intentional, upgrading luck to level 4 and using scratch bot on the level 3 $20 mini scratches causes 1% chance for $30, 1% chance for $67, 28% chance for $133 and a broken 70% chance for ~$650.
Basically it gives no insentive to gamble with the quick cash, apple tree or that acursed lucky cat.
Also is the fan supposed to be useless? That it would "blow" scratch cards to the scratch bot instead of needing to drag them but it ended up doing nothing. So is it cosmetic?
