The Slots with the Highest RTP

Return-to-player (RTP), represents the percentage of wagered money that a slot game is expected to pay back to players over time. The best slot sites will always make this information easy to find.

A higher RTP signifies better player odds and a lower house edge, with the average for slots being around 95-96%. Remember, RTP is a hypothetical average and should not be considered a guarantee.

Progressive jackpot slots often come with lower RTPs due to the nature of their massive prize pools. While these games can offer the potential for huge wins, the higher portion of wagers goes into funding the progressive jackpots.

Volatility (or variance) is different from RTP. Volatility refers to the frequency of payouts. High volatility slots have fewer wins but larger payouts on average. A range of RTP and volatility is a mainstay at the best payout online casinos.

Popular High Stakes Titles

While slots might not be the initial choice for high-stakes gaming, several titles cater to high rollers. Though average bets on slots vary, we consider high-stakes slot titles to be those accommodating bets over £50 per spin. Here are the best online slots with high limits:

Online slots often offer more flexible betting limits compared to their land-based counterparts found in UK casinos. This is due to the digital nature of online platforms, which can accommodate a broader range of wagering options.

Slots Glossary – Common Terminology

Slots Glossary
    • Bonus Feature SlotsA special kind of slot that offers a bonus round in which it’s possible to win free spins, jackpots, and other special wins.
    • Bonus Multiplier SlotsOn this kind of slot machine you will be awarded a bonus for playing the maximum number of coins per spin. For example: If you bet 1 coin per spin, a combination pays out 4 coins, had you played 2 coins per spin that combination would pay 8 coins, but had you played 3 coins per spin you would have won 20 coins. As you can see there is a bonus of 8 coins awarded for playing the max. coins per spin. (20-12=8).
    • Coin Size Some slot machines will let you choose the size of the coins you play with. For example: A machine takes 3 coins per spin but you can choose the coin size to be either $0.25, $1 or $5.
    • Diamond Slots The Diamond Slot is a very popular Las Vegas slot machine on which some of the reel symbols are diamonds.
    • Fruit Machine A classic slot machine where the symbols are different kinds of fruit – like cherries, melons, peaches and bananas.
    • Loose SlotsA slot machine that is ready to pay out a big win. Not actually a truthful term, just a superstition.
    • Multiplier SlotThese kind of slots are recognized as a machines that DO NOT offer the player a bonus for playing the max. number of coins per spin. For example: If you bet 1 coin per spin a combination pays out 4 coins, Had you played 2 coins per spin that combination would pay 8 coins. Had you played 3 coins per spin you would have won 12 coins. As you can see there is no bonus awarded for playing the max. number of coins per spin. These kind of slots are not bad at all, and you should actually look for this kind of slot if you don’t like to bet more then one coin per spin. Also see the slot term: Bonus Multiplier Slots.
    • One Armed BanditAnother word for a slot machine. The name refers to the fact that slot machines used to have a handle that the player had to pull to get the reels spinning.
    • Pay CycleA popular rumour is that a slot machine goes through ‘cycles’ – where it will sometimes pay out winnings to players, and other times play to take in profit to the casino. Personally, I think this is just a rumour – as today’s random number generators simply don’t work like that. Perhaps such cycles did appear in the past – but not with today’s slot machines.
    • Pay Table A table of symbols that shows the winning combinations of symbols for that particular slot machine. Normally the pay table is located on the front of the slot machine.
    • Payline This used to be the middle line on the slotmachine display – but that is not always the case today. Nowadays, some slots have up to 9 paylines – the more coins you play per spin the more paylines are normally activated. Symbols have to line up on the paylines for the player to win prizes according to the pay table.
    • Payout PercentageThis is the amount of $$$$ a slotmachine pays out in winnings; on average, for every $100 that has been wagered on the machine. For example: A slot machine has been set to pay out 95% in winnings in the long run. So every time $100 has been wagered, the machine will pay out $95 to the players. Remember that this is in average seen over the entire life time of the machine, it doesn’t mean if you put $100 in such a machine and wager $100 you will end up having $95 left. Over the short-term you could win a big jackpot, but you could just as soon have a bad run and lose most of it.
    • Progressive Jackpot A slot machine with a jackpot that grows until a lucky gambler wins the big prize. The jackpot is then reset and starts growing again until the next very lucky player comes by and wins.
    • ReelsThe vertical display wheels that shows the symbols.
    • RTP Return to player rate. The statistically-likely monetary return percentage of a game over an extended period of play. See also: Payout Percentage.
    • Sim SlotsShort for simulating slot machine or video slot.
    • Take CycleThe opposite of a ‘Pay cycle’. A popular rumour is that a slot machine goes through ‘cycles’ – where it will sometimes pay out winnings to players, and other times play to take in profit to the casino. Personally, I think this is just a rumour – as today’s random number generators simply don’t work like that. Perhaps such cycles did appear in the past – but not with today’s slot machines.
    • Tight SlotsA slot machine that is NOT about to pay out a big win.
    • Video SlotsSimilar to a slot machine but the mechanical reels have been replaced by a video screen.
    • Wheel of Fortune SlotsThe ‘Wheel of Fortune Slot Machine’ is a very popular slot machine in Las Vegas Casinos, offering a huge Jackpot.
    • Wild SymbolA symbol that can substitute for other symbols – it’s very similar to a wild card in a card game – you can use it to complete a winning combination.
