The Return to Player (RTP) matters as it shows players the house edge on each casino game, including slots and table games. It is represented by a percentage that indicates how much will be paid back over time.
For instance, in a 98% RTP slot, the house edge is 2% and players can expect to win around £98 for every £100 wagered. The best online slots payout percentage exceeds the 97% mark. We invite you to read more about what RTP is in our dedicated article.
Volatility in slots points out how often a slot is expected to pay out and how big the win would be. There are three main volatility levels – low, medium, and high – although a mix of two is also possible. The best slots to play can have any volatility so we recommend choosing one based on your preferences.
Low volatility slots pay out more often but the wins are smaller in value. Our team recommends Blood Suckers and Starburst (NetEnt), Wild Scarabs (Microgaming), or The Catfather (Pragmatic Play). Low volatility slots are best suited for casual players or beginners who are learning how to play slots.
Casino slots with medium volatility have more frequent and bigger wins than those with low volatility. Some popular examples are Gypsy Rose and The SlotFather II (Betsoft), White Rabbit Megaways (BTG), as well as Immortal Romance (Microgaming).
Highly volatile slots have higher average payouts. However, the risk is higher as payouts are less frequent to low volatility slots. Many high RTP slots come with high volatility. Book of 99 (Relax Gaming), Mega Joker (NetEnt), and Sugar Pop (Betsoft) are some of the most popular best paying online slots in the UK with high volatility.
Along with a thrilling and entertaining experience, the best paying slots we featured in our list provide exciting bonus features. In the next part of our guide, we’ve examined these in more detail. Furthermore, we’ve given our recommendations for the best payout slots in the UK with such features.
Free spins are the most common bonus feature that almost all of the best paying slots in the UK offer. Here you benefit from a number of spins where you can win without placing a wager. In many slots they are triggered randomly when you land three or more scatter symbols. Alternatively, many of the best UK slot sites offer a bonus buy option when possible.
It’s generally during free spins where the excitement kicks in. You can land more frequent and larger-value multipliers. These types of bonuses typically award the highest payouts. Blood Suckers (NetEnt), Gypsy Rose (Betsoft), and White Rabbit Megaways (BTG) are the best casino slots to play that offer a free spins bonus round.
Several of the best casino slots to play offer a gamble feature that is triggered with every win. Here you are asked to predict the outcome of an event, such as a coin toss, to double or quadruple your winnings. However, since you also risk losing it, we recommend gambling responsibly to limit your losses. Gypsy Rose (Betsoft) and Thrones of Persia (Tom Horn Gaming) are two high RTP slots that include a gamble feature.
Whenever a winning combination appears on the grid, the symbols of the win disappear and are replaced with new ones. This boosts your chances of a win as more than one win is possible on the same spin. Sugar Pop (Betsoft), Big Bad Wolf (Quickspin), and Aztec Powernudge (Pragmatic Play) all provide this feature throughout their gameplay.
Progressive jackpot slots can offer life-changing rewards that run in the thousands or even millions. Every time a player places a bet, a fraction of that bet is placed in the jackpot until a lucky winner wins the entire pot. Mega Moolah by Microgaming is one of the most renowned online slot games with a jackpot.
Infinite reels, cascading and expanding reels, Megaways, as well as giant symbols are some of the exciting mechanics that are incorporated into the best slots to play. White Rabbit Megaways (BTG) and Immortal Romance (Microgaming) are two popular best payout online slots in the UK that have such bonus symbols.
