The only description I've found says "You can win a small random amount of sP from the Slots Coin, and random items, or stat boosts from Special Coins. " Doesn't sound that good since even the cheaper one I have costs 45k... I'm not sure if I want to spend them to win "A small random amount of SP", I don't really care about stat boosts and I guess the items aren't rare, so... D: Did you guys ever win something special using them?

I normally get junk items, but I have gotten a SubQ item before! I'm in it for the stats tbh.

Items more valuable then the coins themselves are very rare and sP given out doesn't match either. I give it a try only for stats for my pet too (and also: that one or two coins a week if sold don't give so incredibly much sP, simple restocking/questing will give much more, so for me it's not any loss if I gamble a little, and get junk item for them instead).

Personally, I think it's fun to use all the random machines on the site. If you'd rather have the sP from selling them than the experience, I'd sell them.
