There are plenty of things that make slots the best games at every online casino. First off, they are packed with in-game bonuses such as free spins, jackpots and bonus rounds. Not only that, but they are extremely diverse as they vary depending on their theme, payline system, number of reels, type of jackpot, etc.

Not only that but slots are known for having a decent Return to Player (RTP) rate. As you know, RTP represents the stakes that players receive back over a certain period. The higher the RTP rate of the slot is, the higher the returns are. RTP is one of the main factors that indicate the quality of a slot which is why I’ve come up with a list of my 5 favourite slots with the highest RTP.

Blood Suckers (NetEnt) – 98% RTP

The first slot on the list is Blood Suckers by NetEnt. This game is among the slots with the highest RTP rate in history as it is clocked at 98%. Blood Suckers was released back in 2013 and proved to be a massive hit thanks to the fact that it is extremely simple to play.

It comes with a low volatility rate and has a 5×3 layout, meaning that once you access it, you will see a grid containing 5 reels and 3 rows. Additionally, Blood Suckers has 25 paylines on which you can form winning combinations and there are three in-game bonuses – the Wild symbol, free spins and bonus rounds.

The free spins mode is triggered when you land at least 3 Scatters on the reels. Scatters are represented by the Vampire Bride and once you trigger the bonus feature, you will receive 10 free spins. The interesting part about it is that a multiplier is also present during free spins.

Rainbow Riches: Pick ‘n’ Mix (Barcrest) – 98% RTP

Rainbow Riches is one of Barcrest’s most legendary releases and that is why the provider decided to keep the trend going. Rainbow Riches: Pick ‘n’ Mix is one of the sequels of the original title and this game comes with an RTP rate of 98%, the same as Blood Suckers.

Rainbow Riches: Pick ‘n’ Mix features 5 reels and 3 rows as well as 20 fixed paylines on which you can form winning combinations. The game’s volatility rate is medium, meaning that its jackpot drops often, so you can expect decent winnings here.

The best part about this Barcrest title is the fact that it comes with quite a few interesting bonus features:

• Pots of Gold
• Cash Crop
• Road to Riches
• Magic Toadstool
• Free spins

These bonus features make the gameplay all the more exciting and even though Rainbow Riches: Pick ‘n’ Mix was released in 2016, Barcrest made sure that it meets the industry’s latest standards and that is why it is optimized for mobile use.

White Rabbit Megaways (Big Time Gaming) – 97.7% RTP

Big Time Gaming is known for inventing the Megaways feature in which each spin can result in up to 117,649 paylines. White Rabbit Megaways is a product of that type as this entertaining slot comes with an RTP rate of 97.7%.

Thanks to the Megaways feature, the number of rows can be between 2-7, while the number of reels is 5 and the number of paylines is set at 16,807. There are a couple of interesting bonus features that are included in White Rabbit Megaways, such as the Bonus Wild, free spins and the Feature Drop option.

Thanks to Feature Drop, players can purchase free spins in the game.

Zeus Lightning: Power Reels (Red Tiger) – 97.7% RTP

My fourth slot on the list is a Greek mythology-themed game by one of the world’s most reputable game providers – Red Tiger Gaming. Zeus Lightning: Power Reels is a 7-reel slot that features 30 paylines on which you can form winning combinations.

It also comes with a high volatility rate, meaning that its maximum jackpot exposure is pretty high and set at 4,500 x the stake. There are 9 featured regular symbols, divided into low-paying and high-paying categories.

The Wild symbol, which substitutes regular symbols, will help you form winning combinations whereas the Scatter symbol is the key to triggering the free spins mode in the game.

Big Bad Wolf (Quickspin) – 97.3% RTP

Finally, we have Big Bad Wolf, an online slot by Quickspin that also has a relatively high RTP rate as it is set at 97.3%. This is a rather old release as it hit the market in 2012, but thanks to the numerous great features and unique gameplay, Big Bad Wolf remains a popular choice to this day.

Its volatility rate is medium and there are 25 fixed paylines on which you can form winning combinations. Additionally, its layout consists of 5 reels and 3 rows and both Wild and Scatter symbols are featured.

As for the bonus features in the game, we have Swooping Reels, free spins, as well as Moon symbols. Multipliers in Big Bad Wolf are featured and they can boost your winnings. Thanks to the popularity of this slot, Quickspin has come up with a few sequels, one of which is Big Bad Wolf Megaways.
