Any player who wants to maximise their chances of winning big at online slots needs to understand what is meant by the term RTP.
An RTP (or Return to Player Percentage) is a term used by online casinos to describe the percentage of all of the money wagered that the slot will pay back to players in time, or, put more simply, how much of all the money put in the machine gets returned to the player.
For example, a slot with an RTP of 94% will give approximately £94 back for each £100 put in.
The RTP Scale
Once you know what the slot’s RTP is, the next step is to work out what that means for your chances of success:
• Under 93% – low
• 93%-95% – acceptable
• 95%-97% – good
• 97%-98% – excellent
• 98% or above – the best possible chances
As you can see, a higher RTP means that the odds are more favourable and you will have a greater chance of being a winner when playing that slot.

How Do Players Check A Slot’s RTP?
The majority of online slots have their RTP listed in their paytable or in the rules of the game.
It often needs to be looked for, however most software providers supply their RTPs somewhere.
In the event that you struggle to find an RTP for your chosen game, you may want to consider switching to a different slot instead.
Which Online Slots Can Guarantee A Win?
Unfortunately, although the slots outlined here offer you the best chances of scooping a win, there is no online slot that can guarantee that you’ll make a profit as this would mean that the RTP would need to be above 100% which would result in the casino becoming bankrupt in no time!
However, on the upside, some slots do have RTPs which are as close as you can get to 100%, and the higher the percentage the higher the odds of being a winner, just like the Mega Moolah Jackpot.
Fascinating RTP Facts
As a rule, franchised or big name slots only have a low RTP.
This is because the game developers must pay high sums if they want to use an image and name for a popular and famous title such as Jurassic Park, Marvel Comics or The Terminator.
As game developers have to recoup these high fees from somewhere, they lower the RTP in order to make up the difference.
Many of the highest paying slots come from NetEnt, Thunderkick or Microgaming, and this is something you might want to keep in mind when choosing a slot to play.
Although progressive slots often boast a relatively high RTP, it’s important to remember that these figures include the high progressive jackpot sums, and so the RTP for the base game will be a lot lower.
However, if the progressive jackpot is extremely high or you are playing using bonus money, these slots often represent the best choice if you’re looking for enormous gains.
The top tip for anyone who wants to be a winner at online slots should look for an old slot rather than a brand new one since they are likely to pay out more highly.
The more boring and old the better, and although they may not have the cutting edge graphics and features of the latest releases, these mature offerings are the most likely to be the ones that will help to bolster your bankroll.
Also, make sure to choose online casinos that have the best paying slot games online.
