Superior Casino is one of the most popular Rival-powered casinos, especially ever since they released plenty of slot machine bonuses. New players are welcome with a 100% slot bonus up to $100 and then can receive monthly reload bonuses. The weekly mailers are filled with bonus promotions for slot machines, especially the I-slot machines that have literally transformed slot gaming. The download times for this casino are quite fast compared to Microgaming casinos. Each slot game is downloaded within 5 minutes or less.

There are some good and bad things with the slot machines that Microgaming casinos offer. We’ve been testing a few out such as the Vegas Slot Casino. Their slot machine list is impressive, they have over 300 slot games with different and original themes. That great thing is that you can play all their games for free when you download to try them out before you deposit at the casino. Unfortunately, the download times for some of the slot machines are quite long, sometimes taking up to 1 hour to complete the download. This is annoying when you are eager to start playing and trying new slot machines. On the good side, the slot machines we were able to play have sharp graphics, cool bonus rounds and huge jackpots.

Rival Casinos are mainly focused on slot machines. Rival-powered brands offer cutting-edge software with modern graphics and fancy lobby interiors. Their casino games feature have a wide array of classic 3-reel and video slot machines. Their greatest attraction is the I-slots, interactive slot machines that are more than just regular slot games. I-slots feature the latest in computer animations and sound effects, multipliers and free spins, plus evolving storylines that entertain players as they spin the reels. Rival casinos allows you to add unlimited amounts of fun cash to your account, so you can try out for free all the latest I-slot machines – a new favorite for slot players.
