What is the Online Casino RTP and Which are the Best Slots?

Many vital factors play a role in the effectiveness of slot games, and the RTP is one of these factors. It is the return to the player, and this information is often [provided by the developer. There are various ways to find the RTP of a slot, and this article will introduce three methods. Read on to find out more about RTP and some excellent high RTP slots to play. 

What is RTP?

The Return to Player, or RTP, refers to the amount an online slot will pay out to players in an ideal situation. For example, on a slot with a 95% RTP, there will be a total of a C$95 payout for every C$100 spent on the platform.

To determine the RTP of a slot, developers must consider many spins over a long period. This means that players who play for a short time on a slot will not enjoy the benefits of the RTP – except they get very lucky.

Does RTP Change on Different Casinos?

Yes, it is possible to have different RTPs for the same slot on other casinos. Some developers design their slot titles to have multiple RTPs, leaving the online casino with the option to pick the RTP to offer its players.

Despite the availability of this option, most online casinos must follow the regulations of their licensing body. Most licensing bodies have a minimum RTP for slot games on casinos they license.

Why is the RTP on Online Slots better than Land-Based Slots?

The short answer – NO. Online slots offer much better RTP than land-based casinos for several reasons. One of the reasons why land-based casinos offer lower RTPs is the need to make a profit. Since the space in a land-based casino is limited, they can’t accommodate as many players as an online casino.

This means they need to match the profits of online casinos with a lower number of players, and the best way to do this is by adjusting the RTP of their slots. Since the online casinos have a much lower operating expense, they can afford to offer high RTPs to players.

So, does this mean more players leaving land-based casinos? No. The main reason why land-based casinos remain relevant is due to the gambling experience that is impossible to replicate on online casinos. The hotel rooms, the food, and the various events land-based casinos offer make them excellent holiday destinations.

Is RTP a Random Value Selected by a Provider?

No, there is a lot of work put into determining the RTP of a slot by a provider. On the websites of many slot developers, you will often find them listing mathematicians as a part of their team. This isn’t a ruse, as these mathematicians play a vital role in determining the RTP of slot machines.

In simple terms, these mathematicians evaluate and analyze the various combinations of symbols, jackpots, and bonus features of a slot game to determine the RTP. in reality, the process is much more complex since these mathematicians need to build models when trying to get accurate figures.

Base RTP and Theoretical RTP

The use of the base and theoretical RTP is vital when picking progressive jackpot slots to play. The base RTP is the RTP of a progressive slot when the jackpot is at its initial value. This is a more realistic RTP that you should consider when playing the slot game.

The theoretical RTP is the RTP of the slot as the jackpot value increases. This theoretical RTP is difficult to determine due to the lack of information, but it is helpful in determining long-term winning potential.

In assessing your winning potential on a progressive game, it is a good idea to consider both the base RTP and theoretical RTP. With the base RTP, you have an idea of your winning potential over the short-term while the theoretical RTP provides information on the long-term value of a slot.

Finding the RTP of an Online Slot

Although a quick Google search can get you the information you need on a slot, there are better ways to get the RTP of a slot. These options use information directly from the developers, so you’re sure of getting accurate details. These options include:

  • Game Screen: The game screen of the base game sometimes has the RTP on display. This is true for some slot games, and for others without the RTP on the game screen, try any of the subsequent options.
  • Paytable: All online slots have a paytable that must be available to players. The RTP can sometimes be visible in the table, along with the paylines of the slot.
  • Help Menu or Instructions Panel: If the RTP isn’t visible on the paytable on the game screen, you will find it on the Instructions panel. This panel is usually accessible by clicking on the ‘i’ or ‘?’ sign on the slot.
