How can I tell if a slot has a high payout chance?
Every slot has a return to player (RTP) rate. This tells you the amount that will be returned to the average player over a prolonged period of time.
For example, if a slot has a 95.24% RTP rate, the average player will receive $95.24 back for every $100 wagered.
The results are always completely random. That means some players win, and other players lose. However, choosing a slot with a high RTP percentage can boost your chances of success.
You can use the RTP to calculate the house edge that an online casino takes. Simply subtract the RTP from 100. For instance, a slot with a 95.24% RTP rate has a house edge of 4.76%.
What is the average RTP of an online slot?
Online slots have an average RTP rate of around 96%. That equates to a 4% house edge. Slots with an RTP of more than 97% are generally appealing.
However, there are other factors to consider when deciding whether to play an online slot, alongside the RTP rate. They include the volatility, the bet limits, the maximum win potential, the bonus features, and any progressive jackpots or fixed jackpots.
Why do online slots have better payout rates than physical slot machines?
Online casinos have substantially lower overheads than physical casino resorts. That allows them to take a lower house edge on their games.
For example, casinos on the Las Vegas Strip need to factor in high rents, staffing costs, and energy bills. As such, they held onto 8.1% of all wagers placed on their slot machines in 2024, according to the University of Las Vegas Center for Gaming Research.
That 8.1% house edge equates to an average RTP rate of just 91.9% on physical slot machines on the Las Vegas Strip. That is very low when compared to the RTP percentages found on the best-paying online slots.
How to find the RTP of an online slot
Some online casinos clearly display the RTP rate of each online slot. Examples include bet365 Casino. That makes it easy for you to find the RTP percentages.
If your online casino does not highlight the RTP on each game, you can visit the provider’s website to find out the information.
For example, let’s say you are interested in playing Guns N’ Roses by NetEnt. Just visit the NetEnt site and search for that game. You will then see that it has an RTP rate of 96.98%, which is well above average.
What is volatility?
The volatility rate indicates how often you are likely to win when playing a slot. Online slots generally fall into three categories: low volatility, medium volatility, or high volatility.
- Low volatility games generally provide small, regular wins. You are not going to win a huge jackpot, but your chances of going on a long losing streak are also relatively slim.
- By contrast, high volatility games offer the average player large, irregular wins. That means you need to be prepared to ride out losing streaks while chasing tantalizing jackpots.
- Medium volatility slots fall somewhere in the middle, with the potential for reasonably large wins on a pretty regular basis.
You can consider the volatility rate alongside the RTP when determining whether an online slot is right for you. For example, some players may enjoy the chance to grind out regular wins on Blood Suckers, a low volatility slot with a high 98% RTP rate and a maximum win of 1,014.6x your bet.
Meanwhile, others may prefer chasing a payout of up to 50,000x your bet on Medusa Megaways, a highly volatile slot with a 97.63% RTP rate.

Other tips to maximize payouts
Choosing the best payout slots can theoretically increase your chances of success at an online casino. However, you also need to practice sensible bankroll management and understand how each game works.
Here are our top tips to help you capitalize on the opportunity that the best payout online slots provide.
Carefully managing your bankroll is vital when playing online slots. For example, if you have a $100 playing budget, it would be risky to wager it all on a single spin.
Most experienced players wager a small percentage of their bankroll, such as 2% or 3%, on each spin. That allows you to ride out any potential losing streaks. This is especially important when you play slots with high volatility rates.
Just make sure you wager enough to cover each payline. Most slots have fixed paylines, which means you simply need to choose a bet amount, and it covers every potential payline. However, some slots require you to select the number of paylines you’d like to play per spin. In that case, it can be beneficial to cover all of them.
It is also important to wager enough to unlock the maximum RTP percentage. For example, you need to activate the “Big Bet” feature to benefit from the full RTP rate on Barcrest slots like Monopoly Big Event, Dr. Jekyll Goes Wild, and Legend of Bigfoot. That requires you to play substantial bets on each spin.
You often need to activate certain bonus features to receive the highest possible RTP rate when playing online slots. For example, White Rabbit Megaways has a standard RTP of 97.24%, but that increases to 97.72% if you activate the buy bonus option.
Meanwhile, the RTP rates on certain games depend on the strategic decisions you make. Most slots are simple games of chance, but some require you to implement the optimal strategy.
That is certainly the case on Codex of Fortune and Mega Joker, two of the best payout online slots from NetEnt. Mega Joker’s RTP can range from 85.28% to 99%, and you need to play the skill-based Supermeter mode to receive the full RTP.
An online slot’s RTP rate simply highlights the return that the average player can expect to receive over an infinite period of time. However, in the short-term, there is always the potential to embark on a winning streak when playing an online slot.
The results are powered by Random Number Generators, which are independently verified to ensure fairness and accuracy. It means that some players will win in the short-term, and others will lose. If you enjoy a winning streak, be prepared to stop playing and walk away with a profit.
Over the long-term, the results will revert to the mean. Online slots have an inherent house edge, so you cannot beat it forever. If you secure short-term success, consider quitting while you’re ahead.
Never play with money you cannot afford to lose. Even the best payout online slots have a house edge, and success is never guaranteed.
That means you should set a strict playing budget, which does not include money that you need for rent, bills, and other necessities. Never treat online slots as a way to overcome financial difficulties or achieve financial goals.
These games should be enjoyed in moderation, as part of a balanced lifestyle. Avoid playing while drunk, stressed, bored, or angry, and do not chase losses.
Make sure you claim bonuses at online casinos. They allow you to regularly play slots with house money, and the best promos can effectively reduce the house edge built into online casino games.
Try to claim welcome bonuses that come with relatively low playthrough requirements (such as BetRivers online casino or FanDuel online casino, which only require a 1x playthrough.) Also look out for ongoing promos, and participate in rewards programs, which offer ongoing opportunities to unlock bonus credits.
Redeeming as many promos as possible can improve your chances of success when playing online slots, provided the bonuses come with realistic wagering requirements.
Reading reviews and scanning forums can help you discover the online slots with the best payouts. You can also learn how each game works from the experts and your fellow players.
Most online slots are straightforward games of chance. You simply press a button to spin the reels, and you win a prize if certain matching symbols appear on a payline.
However, some high RTP slots require strategy or skill, such as Mega Joker and Codex of Fortune. In that case, it can be helpful to read reviews and forum posts covering those games. You can also play those games in demo mode while learning the ropes, and then switch to real money play when you have mastered them.
Make sure you only play slots at regulated online casinos. If you are in Connecticut, Delaware, Michigan, New Jersey, Pennsylvania, Rhode Island, or West Virginia, make sure the online casino holds a license from your state regulator.
That is the only way to ensure that the games are not rigged, that you will be treated fairly, that your details will be kept safe, and that you will be paid out on time if you win. Avoid unregulated online casinos based overseas, as many American players have been scammed at those sites.
In most other states, you can play at social and sweepstakes casinos. The only exceptions are Idaho, Michigan, Nevada, and Washington. Make sure you play at a legit social casino that complies with state and federal regulations, such as WOW Vegas, High 5 Casino, or McLuck.
