I spent around 850 credits on the twenty-five, & I got:
- 1 SEC (that I didn't particularly want)
- 9 gift cards
- 12 VirtuaGirl cards
- 1 DeskBabes card
- 13 Istripper cards
- 1 Istripper X card
That's 37 cards, and 13 of them are worth 11 or 8.8 credits (35%). So the average cost of a card is about 23 credits, mostly for cards you wouldn't buy in the first place.
And I didn't win any Joker nor 150 credit prize. I didn't actually look for errors (as some reported) in 3 symbols aligned, so I might have lost credits/prizes there.
I wouldn't have played if it wasn't for filling the last 2 joker bar.
I think this game should cost less, 10 or 12 credits, the winnings should include a x5 credit win (50 or 60), and exclude random cards. Then you would only play for Joker, Gift cards and SECs, and it could be worth it.
