Highest Paying Online Slots with RTP up to 99.32%
Slot generosity can be measured based on their theoretical RTP values. Most games are programmed to pay around 93-97% of the wagered amount back to players. But these are just most common values, while some of the most profitable titles can pay more.
Playtech is the most prolific supplier when it comes to high RTP slots. Their titles dominate this category, while the record return to player belongs to the company’s slot machine. Goblin’s Cave can be crowned the most generous online casino slot with 99.32% RTP, which is absolutely amazing for this game category.
Goblin’s Cave is a simple 3×3 game that, unlike many other classics, can offer a bonus game along with some wilds. There isn’t much to be fascinated about this game, but it has one interesting feature. Players can choose to hold any one or more reels and then activate respin for better chances of landing a nice win.
There are two Playtech slots that offer 99.1% return, second highest slot RTP. These are Ugga Bugga and Ocean Princess, the latter being very similar to Goblin’s Cave. Ocean Princess players can use Hold feature to keep certain reels and then respin. But this time the slot offers not 3×3, but 3×5 reel set. The difference is Ocean Princes has no bonus round; another thing is symbols can land in between pay lines making it harder to land a winning combination.
Ugga Bugga is similar to Ocean Princess, but with two 3×5 reel sets. Watch the video below to see what it looks like. There are just wild symbols and no bonus game.
All three of the above mentioned games are pretty boring, and don’t have much entertainment value. But players can be forgiving as these are three most profitable online casino slots.
Other developers also have some of the most lucrative online slots in their portfolios. WMS, for instance, can offer Nemo’s Voyage with 99% RTP. You probably won’t instantly fall in love with it, but this game is incredibly engaging thanks to its smart features that perfectly complement the theme.
One of the key elements of the game is the set of wild symbols. They get activated one by one as the submarine gets deeper and deeper. To monitor the process of diving there’s a special depth gauge on the right side of the screen. With every spin the submarine dives deeper activating first Multiplier Wilds then Pressurized Wilds, Clumped Wilds and then Wild Reels.
Collecting the variety of wilds is fun, but as the submarine gets deeper, it experiences increased pressure that in the end forces it to rise. However, the journey back to the surface will be equally rewarding as players get the same wilds activated in the reverse order.
WMS slots aren’t the most popular ones, but there are some amazing titles like, for instance, Nemo’s Voyage. It has a decent entertainment value and deserves extra attention for being one of the most profitable online slots.
Ooh Aah Dracula is another 99% RTP game. But it is far from offering similarly exciting gaming experience. It’s a rather usual title featuring simplistic visuals and a standard round of free spins. Apart from its high theoretical return, players will appreciate its Hi Roller feature buy option that grants five free spins.
Tropic Reels is one more Playtech title with unusually high return to player. It is very similar to the mentioned above Ocean Princess except for 0.1% lower RTP and a different theme. So, basically, you can choose any one of the two and get the same experience.
NetEnt focuses on delivering entertaining slots and not the most generous. But it has Mega Joker designed with 99% RTP. This 3×3 classic has five pay lines and two sets of reels. The lower reel set is used to play the main game and the upper one is there for the Supermeter mode that gives players a chance of landing increased payouts. Supermeter mode can be charged using winnings from the main game.
98.8% to 98%
This RTP range is also considered to be extremely high, and there are several slots that fall into this category.
