Finding the best odds on slots online requires doing a little research. If you don't want to do that research yourself, here's a review of the online casino software companies with the best odds slot machines.
Rival Gaming Best Odds Slots
Rival Gaming casinos offer several slot machines which offer great odds for winning the big jackpots. Among the "best odds slots" of the classic 3-reel games at Rival: Fantastic Fruit slots, Gold Rush, Sevens and Bars, Surf Paradise and Chicken Little.
The absolute best slots odds are found on Fantastic Fruit slots. Gold rush has a small jackpot at 400 coins, but this means you have a solid chance of walking away with the pot. Surf Paradise Slots and Sevens and Bars slots each have 2,500 coin jackpots. The best odds slots with the biggest jackpot is Chicken Little, with 4,000 coins on the return.
Rival Gaming also offers several video slots which have great odds. Among these you will find Metal Detector, Dog Pound, Atomic Age and For Love Of Money.
Metal Detector pays off a 1,000 coin jackpot with the best odds of winning it. Dog Pound has a jackpot of 2,500 coins and Atomic Age offers one of 3,000. For Love Of Money has the biggest jackpot of the four, at 5,000, though the pot odds are comparable.
Cryptologic Online Slot Machine Odds
Cryptologic casinos have some of the best month return rates among those sites which publish their numbers. (Unfortunately they don't accept USA-based players.) InterCasino, part of the Cryptologic online slots network, has a monthly payback over 96%. Cryptologic is some of the best software to use when playing online slots.
Microgaming Online Slots Odds
Microgaming slots claim to have a monthly return around 95.40%. You might have to sift through their line up to find best odds slots, but you can find some over 96%. Most Microgaming casinos accept USA based players from 39 states.
Playtech Online Slot Machine Probabilities
Playtech slots offer a return rate which hover around 96%. From month to month, these numbers fluctuate from the 98% range all the way down to 95%+. Playtech casinos don't accept USA based players.
Best Odds-Slots - Fortune Slots
Fortune slots from Net Entertainment claims a regular payback percentage over 97%. Gold Rush and Wild West by the same company publish "theoretical returns" of over 96%.
Realtime Gaming Slots Odds
Real Time Gaming (RTG) allows its vendors to select their own payback percentages, so you're never quite certain what kind of percentage you're getting from any particular machine. That being said, we've had a lot of fun and some really good times playing the slots at RTG casinos. Some RTG casinos accept USA players; some don't.
Boss Media Online Slots
Boss Media has a nice network of casinos which feed into progressive jackpots. Some of the better progressive slots are on Boss Media, if you are looking for high end options. This is made up in the odds you get on the slots. As far as best slots odds, Boss isn't in the top echelon.
