While picking a slot site is important, it's also key to do your homework on the developers that build and design the games. Today, there are almost as many slot developers as online casinos, and the old hands now do battle with a generation of slick online software operators. The new kids on the block pack their games full of bonus features, 3D graphics, and animations. They also collaborate with Hollywood studios and TV companies to bring out branded slots for the mass market.

Slot game developers form partnerships with online casinos to feature their games. The best casino sites will only buddy up with developers that provide the best gaming experience for players. Games from leading developers, like IGT, NetEnt, Microgaming, WMS, and Aristocrat can be found at thousands of online casinos around the world due to the popularity of the games and the trust in the brands.
