Best RTP Slots and Best Winning Chances

If you are looking to win more often playing the best online slots then you need to understand, and where to find information on the slots RTP.

RTP% = Return To Player percentage

First up is understanding what each slots RTP [return to player] stand at. This will help you choose the right slot and the slot that pays the most back in winning spins and bonuses.

What is Return to Player Percentage in Online Slots?

Return to player is the percentage of wagered money is return in winnings over time when playing slots on a casino app.

Long losing runs and good winning runs will over course be over a shorter period and will return lower and higher percentages will be useful in the short term, but once evened out over time, the RTP is an accurate view of how the slot is set up.

Quite simply, the higher the RTP, the higher the percentage of money wagered is returned in winning spins and bonuses.

98.9% RTP Example

For every £100 wagered, the game would return £98.90 to the player over “time”.

How long is “time” in this case?

Well, there is actually no defined ‘time’ as it were, it certainly can’t be narrowed down to an exact number of spins, and of course, if it were a very tight timeline it would make it impossible to win on slots in the short term, which, of course, you certainly can.

The advice is simple, if you get ahead, regardless of the growth of your original bank, eventually you will lose in the long term, so stopping while you are ahead has never been apter.

RTP Levels are to ensure the Casino Wins.

The RTP% ensures that the longer you play the less chance you have of winning. It is a harsh fact of online slot play, that if you don't quit while you are ahead, it is most likely that you will lose.

You will already have figured out that if you flip the percentage RTP, you will have the house edge.

So in this example where we are looking at an RTP of 98.9%, the house edge on this game is 1.1% which is generous in comparison to standard single zero roulette house edge of 2.70%

If you are playing any slot with an RTP of at least 97.3%, you are getting better odds than if you play Roulette.

The table at the head of this article has a list of the highest RTP slots by the provider and where you can play them. They all come under the 97.3%

When choosing a slot and best payout percentage, try to keep your choice to the recommended RTP level as outlined above or consider this handy guide:

RTP When to Play
97%+ Most Often
95-97% Less Often
93-95% Rarely
Under 93% Try to Avoid
The lowest RTP slot we have listed is 96.16%

You may find slots based around Films, TV series, Bands or Sporting Events. In many cases, these will be licensed by brands whereby the game creator/provider will have to pay to brand the slot game.

This is an underlying cost that will need to be covered and often you will not find these slots falling into the list of best payout online slots.

Indeed, in the list of 63 online slots we have here, there is not a single brand name included.

High Payout Online Slot FAQs

  • What casino pays the most in slots?

    The online casino that pays the most out on slots would most likely be the one that has the highest number of slot games available to play combined with the highest number of active monthly players. In terms of which pays out the most based on the payout averages of the slots available, then someone would have to collate all of that information and figure out the average. 

  • Which online casino has the best payouts?

    No specific casino can be determined against another based on payout given that all casino games have set house margins and thus depending on the level of play pay out relatively the same. What might differentiate one online casino from another is the rewards program or loyalty scheme they have in place for players. 

  • What are the best slots to play online?

    The best slots to play online will depend on what you are looking for. If you want big wins, then progressive jackpots lost might be what you want, although be aware that the edge on these is bigger for the house. If it is simplicity, then there are plenty of three-reel, single win line pays slots to play too. Read slot reviews to see which ones you would prefer.

  • Are online slots worth it?

    Online slots are worth playing if you find them entertaining, but always you should consider and remember that they are provided for gambling entertainment only and have a house edge to ensure that you can not win in the long term. You should always gamble only as much as you can comfortably afford to lose.
