The International Slots League is a series of tournaments hosted by Platinum Play and other online casinos in the Fortune Lounge group. It's packed with over 13 large, scheduled multiplayer tournaments every day as well as smaller Sit & Go tournaments for those in a hurry.

You can play for over $40,000 in prize money weekly, and the lion's share of that money is allocated to an amazing $20,000 guaranteed weekend tournament. The buy-in to this massive tournament is only $20, but you can even win your way in for free through daily freerolls.

All of the tournaments are competitive multiplayer games that are spread across several different slot machines. Many players will be delighted to learn that some of the tournaments are played on the amazingly popular Tomb Raider slot, while others are played on the feature-packed Thunderstruck slot machine.

Platinum Play, which is one of the casinos hosting the International Slots League, is open to all players including those from the US. What makes the casino even more interesting is that it's currently offering a $400 sign-up bonus - read our full review or more information.
