How to choose the best online slots for real money
The best online gambling apps host more than 1,000 slots. These are the key points to consider when searching for high-quality games at the best online slot sites.
Look for slots that offer a variety of bonus features
Choosing an online slot with several bonus features can help you stay engaged. Some online slots are pretty basic, and players quickly grow bored of the monotonous gameplay. By contrast, the best online slots offer a wealth of intriguing features, which ensures the action remains varied and entertaining.
Check the volatility of the slot
Some players like to play low volatility slots, which tend to deliver small, regular wins. Others prefer highly volatile slots, as they don’t mind enduring losing streaks while chasing large jackpots. Find a volatility level that suits your risk tolerance and seek out appropriate games at online slots casinos.
Keep an eye on RTP value
Try to play online slots with high return to player (RTP) rates. Those games have a low house edge, which theoretically boosts your chances of success. The average online slot has a 96% RTP rate, so anything above 97% is attractive.
Consider the max win
Some of the best slots to play for real money offer huge fixed jackpots. For example, you can win up to 20,000x your bet when playing Extra Chilli Megaways from Big Time Gaming. Others offer progressive jackpots, which give you the chance to win a seven-figure payout from a single spin.
Play online slots from licensed and regulated casinos
Make sure you only play at licensed, regulated online slots casinos. That means you should stick to sites like BetMGM, Caesars Palace, FanDuel, BetRivers, DraftKings, and Bally Bet Casino. They must adhere to strict consumer protection regulations, and their online slots have been independently certified to guarantee fairness and accuracy.
Types of online slots
All online slots follow the same basic premise: you press play, the reels spin, and you win a prize if matching symbols appear on a payline. However, slots also fall into several distinct sub-categories, which have different mechanics and features. These are the different game types to familiarize yourself with.
Progressive jackpot slots
When you play a progressive jackpot online slot, a small portion of your bet amount will go into a communal jackpot pool. The jackpot continues to grow, until one lucky player wins it. These online slots often feature huge prizes, which can exceed $4 million at certain online casinos. Slots players will find the largest progressive jackpots at BetMGM and DraftKings Casino.
Classic slots
These games are inspired by the old mechanical 3-reel slot machines found at land-based casinos in the 20th century. They tend to have low volatility rates, so the average player can expect to secure lots of relatively small wins over the course of a session. Classic slots often feature iconic symbols like bells, fruit, bars, and red 7s, and they don’t normally have bonus rounds.
Megaways slots
An Australian company called Big Time Gaming unveiled the revolutionary Megaways feature in 2011. This feature allows an online slot to have more than 100,000 paylines, resulting in varied, visually stimulating gameplay. Big Time Gaming now licenses out the feature to lots of other studios, so you can play a wide range of Megaways slots at the best online slots casinos. These games often have high volatility rates and large maximum win limits.
5-reel slots
Most online slots now feature a standard 5-reel grid. You’ll still find classic 3-reel slots at real money casino apps, and some games have 6 reels or more, but the vast majority have 5 reels. These games tend to have sharper graphics than old-school 3-reel slots, and they typically offer bonus rounds too. For example, you might be able to trigger free spins with multipliers or perhaps a pick-and-click bonus game.
Bonus buy slots
Certain online slots allow you to jump straight into the bonus round. You will need to pay a fee to do so, which is why they’re known as bonus buy slots. For example, you might be charged 40x your bet to access the free spins round. You’ll then hope to earn more than 40x your bet from the free spins.
Video slots
Video slots replaced the old mechanical slot machines many years ago. These video slot machines were revolutionary, as they used Random Number Generators to deliver the results and audiovisual effects to enhance the gameplay. The term “video slots” now covers most online slots, and it can also refer to 5-reel games that don’t offer Megaways paylines, progressive jackpots, or bonus buy features.
Our top tips for success when playing online slots
There are no guarantees of success when you play online slots, so it’s important to gamble responsibly. However, these tips can theoretically boost your chances of success.
Choose slots with high RTP rates
Every online slot has a theoretical RTP rate, which highlights the amount an average player would receive over a prolonged period of time. For example, a player with average luck would expect $95.80 back for every $100 wagered when playing a slot with a 95.8% RTP rate.
The results are random, meaning that some players win and others lose, but choosing online slots with high RTP rates will theoretically improve your chances of success. The higher the RTP rate, the lower the house edge.
Activate the bonus buy feature if it improves the RTP
You will often find that the RTP rate will increase if you activate the buy bonus feature. For example, it goes from 97.24% to 97.72% on White Rabbit Megaways, which shaves 0.48% off the house edge. Similarly, you can boost the RTP percentage by activating the “Big Bet” feature on Barcrest slots like Monopoly Big Event and Legend of Bigfoot.
Make use of bonus spins
You can increase your bankroll by claiming bonuses at online casinos. The best apps offer you bonus spins and bonus credits, which essentially allow you to play with house money.
Claiming bonuses can effectively reduce the house edge on online slots. Just make sure you only claim bonuses that come with realistic playthrough requirements.
Choose your online slot wisely
Avoid online slots with low RTP rates, unappealing jackpots, and basic gameplay. Don’t play slots from unlicensed software providers, as there are no guarantees that they will deliver fair accurate results. Stick to high-quality slots from elite providers like IGT, NetEnt, Light & Wonder, and AGS. Choose an online slot with a volatility rate that suits your risk tolerance and select a bet size that allows you to gamble responsibly.
Read our reviews
The experts at PlayUSA have reviewed hundreds of online slots. If you’re looking for the best slots to play for real money, check out the in-depth reviews we have for hundreds of slots. You’ll discover the RTP rate, volatility level, bonus features, and maximum win limit on each game, along with our unbiased verdict on the risk-reward ratio.
Practice by playing free slots
The best online casinos allow you to play free online slots in demo mode. That gives you the chance to test out a new slot without risking your own funds. You can also familiarize yourself with the mechanics. If you enjoy the experience, you can switch to playing for real money at any time.
Study the paytable
The paytable highlights the payout you will receive from each winning combo. You can access it by clicking the information logo, the question mark, or the hamburger menu. Check out the payouts on offer and make sure you find them appealing before you begin playing.
My advice:
I recommend playing online slots that offer high RTP rates, exciting bonus rounds, and the chance to win large prizes. My favorite slots include Book of 99, White Rabbit Megaways, Reactoonz 2, Medusa Megaways, Codex of Fortune, and Money Cart 2. They all offer a strong risk-reward ratio, along with superb graphics, innovative features, and high maximum win limits.
However, you may prefer slots with lower volatility rates. I’d recommend signing up with an online slots casino and playing a wide range of slots for free in demo mode. Explore the categories I’ve discussed above – classic slots, Megaways slots, bonus buy slots, and so on – and figure out which online slots you’d enjoy playing for real money.
Real money online slots vs free online slots
You can unlock several advantages by playing free slots online. The best online slot sites allow you to play for free in demo mode, and you can then switch to playing for real money at any point. You can also play online slots for free at PlayUSA. This table highlights the key pros and cons of playing online slots for free or for real money.
| Real money online slots | Free online slots |
|---|---|
| You have the chance to win money on every single spin. | Playing for free allows you to try out new slots before risking your own funds. |
| Some players find online slots more exciting when there is real money riding on the outcome. | You can familiarize yourself with the bonus features and test out strategies when you play free slots online. |
| You will earn rewards points when you play slots for real money at sites like BetMGM, Caesars Palace Casino, and BetRivers. | You won’t benefit from any bonuses, promos, or loyalty rewards if you play free slots online. |
| The best online slot sites offer broad betting limits, so you’ll find penny slots and high-stakes slots. | Certain slots cannot be played for free in demo mode, so you won’t have as many options. |
| You can only play real money online slots in seven states. | Players in all 50 states can enjoy free online slots. |
Top software providers for online slot games
The best online slot sites host games from a wide range of software providers. Each studio has its own specialties. For example, Everi is renowned for producing classic 3-reel slots, while Big Time Gaming specializes in Megaways slots.
This chart highlights the top five providers in the US market. There has been a great deal of consolidation in recent years. IGT and Everi joined forces, while Evolution Gaming swallowed up NetEnt, Red Tiger, Nolimit City, and Big Time Gaming, and Light & Wonder owns Bally, Barcrest, Lightning Box, NextGen Gaming, Shuffle Master, and WMS.
| Slot provider | Popular slots by provider |
|---|---|
| NetEnt | Starburst Gonzo’s Quest Dead or Alive Mercy of the Gods Divine Fortune |
| IGT | Cleopatra Cash Eruption Siberian Storm Da Vinci Diamonds Wheel of Fortune slots |

The Best Payout Slots in 2025
The RTP rate highlights the theoretical return that a player with average luck can expect to receive from an online slot. For example, the average player will expect to receive $9.61 for every $10 wagered on a slot with a 96.10% RTP rate.
Experienced slots players seek out games with high RTP rates, as they have the lowest house edge. This theoretically improves your prospects of success at the best online slot sites. For example, a game with a 99% RTP has a house edge of just 1%, which is appealing.
These are the games with the best RTP rates at US real money online casinos:
| Slot | Provider | RTP | Volatility | Max win |
