The most profitable slot machines offer an RTP of up to 99%!

On the internet, both in online casinos and in traditional brick-and-mortar establishments, you can find thousands of slot machines. Each with its unique features and a promise of a unique immersive atmosphere and unforgettable gaming experience. Choosing the best slot machine depends on many factors and also on players’ preferences. However, if you plan to play for real money, you will definitely be interested in which slot machine gives you the best chance to win. For this purpose, the key value of Return to Player (RTP), which indicates the amount players can expect back from their bets, is absolutely crucial.

What is RTP?

RTP, which stands for Return to Player, is a key indicator for anyone involved in gambling. Unlike sports betting, where profits can be made over time through analytical skills, casino games are designed so that the casino gains profit in the long run and players lose. RTP then provides players an estimate of how much of their wagered money will likely return to them during gameplay. It is, however, absolutely necessary to realize that the value of RTP is always given over a long-term horizon – your winnings were not lost by anyone before you – usually, it is not the case that you would win back your money. It is important to realize that RTP is more of a theoretical indicator, which corresponds to long-term statistics, involving millions of spins. For example, a slot machine with an RTP of 97% would over the long term return 97 CZK for every 100 CZK bet. However, this does not mean that this ratio will exactly manifest itself during a single gaming session. In reality, you may win or lose different amounts, which is common for every player. This principle, for example, applies to jackpots, whose amount has been accumulating for a long time beforehand.

Explaining RTP

Where can I learn about the RTP value?

Information about RTP (Return to Player) is usually available directly on the websites of online casinos – often in the terms and conditions section or in the descriptions of individual games. This figure is also typically stated in the game plan or directly in the machine information on the game screen after it is launched. This section is usually marked with an information symbol or a question mark. Alternatively, you can also find out information about RTP on the websites of the development studio that created the slot machine or from the customer support of the specific casino.

How is the RTP value calculated?

To calculate RTP (return to players), you first need to get a complete overview of the payout schemes the slot offers, including the probabilities of occurrence of each symbol and winning combinations. Only then can you start calculating the RTP value. The formula for calculating the corresponding value is as follows: RTP = (Total expected payouts to players / Total bets by players) x 100% Total expected payouts to players include all player winnings, including winnings from bonuses and jackpots. On the other hand, total bets by players include all bets made on the particular slot. Then the result is multiplied by 100 percent, resulting in the percentage value of RTP. To better understand this calculation, let’s look at a specific example. Suppose we have a slot machine with the following winning symbols and probabilities of occurrence:

  • Symbol A: Win 10x bet, probability of occurrence 1/20
  • Symbol B: Win 5x bet, probability of occurrence 1/10
  • Symbol C: Win 2x bet, probability of occurrence 1/5
  • Other symbols: No win, probability of occurrence 1/2

Let’s assume the player bets 1 CZK on each spin. Total expected payouts to players are: (10 * 1/20) + (5 * 1/10) + (2 * 1/5) + (0 * 1/2) = (0.5) + (0.5) + (0.4) + (0) = 1.4 CZK Total bets by players are: 1 CZK per spin Now we can use the formula to calculate RTP:

  • RTP = (Total expected payouts to players / Total bets by players) x 100%
  • RTP = (1.4 / 1) x 100% = 140%

However, it is necessary to emphasize that typical RTPs of slot machines usually range around 95-98% (in better cases) and obviously from the logic of the thing within the casino’s profit its value will not exceed 100%, because in such a case the casino would be losing money in the long run.

Which slot machines have the best RTP value?

Slot machines in online casinos are purely about luck and chance – this is practically known by everyone who is around gambling and slot machines. However, choosing the right game can ultimately increase your chances of success. Reviews often talk about winning lines, volatility, and RTP. A key factor is then precisely RTP, which is the percentage of money that returns to players over the long term – we’ve already mentioned this several times here. What specific slots should you definitely try? We have prepared a few for you here – and to really give you something to choose from, we’ll list as many as twelve.
