The return to player (RTP) percentage of an online slot machine is the percentage of the money that is placed on bets that is paid back to players as winnings. It is an average calculated over a long period of time and is intended to give an idea of the relative fairness of a game.

The RTP percentage of a slot machine can vary significantly from one game to another. Some games have an RTP that is as low as 70% (typically these are pub fruit machines or other amusement games – which typically are outside of true casinos), while others have an RTP of over 98%. In general, games with a higher RTP are more favorable to players, as they tend to pay out more frequently and offer a better chance of winning. However, it is important to note that the RTP of a slot machine does not determine the odds of winning on a particular spin, as each spin is a completely independent event.

It is also worth noting that the RTP of an online slot machine can be affected by the specific online casino that it is being played at. Some online casinos have higher RTPs for their slot games than others, so it can be worth shopping around to find the best games. Typically online casinos pay around 94-97% RTP on their slot machines, vs land-based casinos with RTPs of 92-96% typical, and vs small community pub pokies which fund community ventures and often have RTPs of only 89%. In this regard, your best “true bet” is likely in an online casino. Your best experience overall may well be in a land-based casino because you can often get free drinks and food comps, and sometimes see free theatre shows and concerts.
