I think Jackpotjoy US (http://www.jackpotjoy.com/us), is a great slots sites. And it’s not just because I happen to work on the affiliate team 
Jackpotjoy is constantly releasing new games every month, many of which are unique and fun slots games.
The newest slots game to be released is called Diamond Bonanza. This is a progressive slot, with Jackpotjoy’s biggest jackpot ever, up to $100,000.
