I used a lot of all of them I don't know exactly but I had 6 or more 10x balls on the green ones then around 5 or 6 or more of the single green ones. From the yellow ones I think I had 11, I'm not sure and from the red ones I had some too. I had collected practically all of them since the last patchinko contest.
I got a girl "Akama" and all the equipment items that are not purple are from the Pachinko, as well as all the gifts.
