It seems the casino game uses Joker Poker with Two Pair minimum for payouts... The pay scheme they use equates to about 55-63% ROI depending on how big your bet is (larger the better). Whether you think the slots will be better than that % is up to you but looks like just a huge rupee sink to me... Better off using it on your guild.
