Return to Player (RTP) is an essential metric when choosing an online slot. The higher the RTP, the more returns you can expect from spinning over time. For this reason, the best RTP slots are in hot demand.
As a slot enthusiast, I’ve played slots with high RTP rates across many casino sites. In this post, I’ll show you the best platforms to find them. I’ll also detail all you need to know about how RTP works and other key metrics to consider when selecting an online slot machine. Let’s get into it.
My top casinos for playing high RTP slots are sweepstakes sites. I picked them because they are available in more US states than traditional gaming platforms. At these best sweepstakes casinos, you won’t play with money. Instead, you use Gold Coins (GC) and Sweepstakes Coins (SC), which are virtual currencies.
Interestingly, the sweepstakes casinos allow you to redeem your SC for real prizes after meeting certain requirements. GC, however, are for entertainment only. You can use them to simply have fun with slots while playing responsibly.
Now that you understand how sweepstakes casinos operate, here’s my list of the top five offering the best RTP online slots:
Real Prize Casino has 500+ Vegas-style games from leading developers such as Relax Gaming, Red Tiger, and NetEnt. On the site, I found thrilling slots with high RTPs, including Joker’s Jewels at 96.5% and Gemstone Rush at 96.77%.
To play the high RTP slots, Real Prize gave me 100,000 GC and 2 SC after signing up. You’ll receive this welcome bonus, too, and without making an initial purchase. If you want to redeem prizes, Real Prize allows a minimum of only 45 SC for gift cards.
The games lobby at McLuck Casino has 1,200+ titles, and the platform adds more regularly. Thanks to this, there are always new reels to spin. The site literally labels them as New, so you can’t mistake them. Based on my review, several of the latest slots have relatively high RTP percentages.
My favorite best RTP slot games on McLuck are Dragon Queen Megaways and Mummy’s Jewels. The titles are rated 96.75% and 96.5% respectively. Notably, the McLuck welcome bonus of 7,500 GC and 2.5 SC will allow you to play with no initial payment when you sign up. You can spin via the website, but I recommend using the mobile app more.
One reason why Stake.us is popular among US players is its lineup of Original games with favorable RTPs. Among them are slots, which offer some of the highest returns compared to other sweepstakes casinos. My best picks are Tome of Life and Scarab Spin, each featuring a 97.84% RTP. Another decent title is Blue Samurai, which offers a 96.7% RTP.
Stake.us also has the biggest welcome bonus I found during my review. The site offers 260,000 GC, 55 SC, + a 5% rakeback to new players after registration. Notably, Stake.us is a crypto sweepstakes casino, meaning you can redeem prizes via BTC, ETH, USDT, and others. The processing time takes only a few hours.
High 5 Casino has been around since 2012, and the platform is affiliated with High 5 Games, a renowned game developer. Consequently, I came across 300+ exclusive online slots from High 5 Games at High 5 sweepstakes casino. For context, these titles are not featured on other alternative platforms.
The exclusive slots on High 5 Casino have an average RTP of 96%, which is decent. While on the site, I played Da Vinci DeluxeWays, 88 Drums, and Jewel of Alexandria. I got some GC and SC from the High 5 Casino daily and 4-hour bonuses after registering without an initial purchase. If you choose to buy the optional GC bundle, you receive 700 GC + 55 free SC + 1 SC daily for five days + 400 Diamonds for $29.99.
If you sign up with CrownCoins Casino, you get 500+ sweepstakes slots to play. In the collection, there’s a category for jackpot slots, which houses thrilling titles. These games have progressive GC/SC prize pools that keep increasing as more users play.
From my sessions, the top slots in terms of RTP include Gates of Olympus at 96.5% and Hot to Burn at 96.71%. With the CrownCoins welcome bonus of 100,000 CC and 2 SC, you can begin playing these jackpot slots with no initial purchase. It’s worth mentioning that CrownCoins Casino has an iOS mobile app, but there’s none for Android at the moment.
Return to Player (RTP) is basically the percentage of plays a game is designed to give back to users over time. At sweepstakes casinos, the RTP shows the amount of GC or SC you can get back from your spins in the long run.
For example, if a slot has a 95% RTP, it means that for every 100 GC or SC you wager, the game theoretically returns 95. I must stress that this percentage is an average calculated over thousands or millions of spins. It’s not based on individual sessions, which can vary wildly.
When you keep RTP in mind, you can easily pick slots that give you a better shot at stretching your GC or SC playtime. For instance, a higher RTP means more returns in the long run, which is handy if you wish to retain more of your virtual currencies. That said, keep in mind that everything is not based on RTP alone. Chance also plays a big role in determining slot outcomes.
When it comes to RTP, higher is generally better. Of course, a 99% RTP will give you back more Gold Coins or Sweepstakes Coins than 95%. That said, best is usually subjective, because online slots come with a wide range of RTP rates.
Based on my experience, most slots at sweepstakes casinos have between 90% and 98%. With this in mind, a decent RTP will be at least 95%. During my reviews of the best RTP slots, I took things a step further by selecting sites featuring titles with a 96% RTP or higher.
It’s rare to find reels with up to 99% RTP, and 100% is pretty much impossible. That’s because a house edge must always apply to the casino’s advantage. For context, the 100% minus the RTP gives you the casino’s house edge. If the RTP is 95%, the house edge is 5%.
If you want to know the RTP of any online slot, it’s pretty simple. From my expertise, there are two main ways to go about it, including:
Keep in mind that all sweepstakes casino games have an RTP, including table games, live dealer titles, and instant wins. They’re all programmed to return a particular amount of GC or SC in the long run. In my opinion, if a slot doesn’t make its RTP public, it’s not transparent. As such, I wouldn’t recommend playing such a title over time.
The RTP of an online slot is always made available by the game developer or an independent testing lab. It’s not something you have to calculate yourself. Nevertheless, if you want to understand the match, it’s not complicated.
To calculate the RTP percentage, you take the total amount of GC or SC a slot machine returned to players over thousands or millions of spins. Then, you divide by the total amount GC or SC played. I’ve provided the formula below:
For example, if a slot returned 95,000 GC after 100,000 GC was played across a million spins, the RTP would be 95%. Like I said, the formula is simple, but getting the data for the calculation isn’t. You likely won’t be able to get the total amount of GC/SC returned and played on a specific slot over time from a sweepstakes casino.
Over the years, some slots have stood out for their crazy-high RTP percentages. According to my research, these are the top ones:
This title boasts a wild 99.32% RTP, which is one of the highest ever. It’s a simple 3-reel slot with a hold-and-win feature and treasure chest bonuses.
Developed by none other than NetEnt, Mega Joker hits a 99% RTP in its Supermeter mode. The slot is retro-style, so it resonates with traditional reel fans.
Also at 99% RTP, this Greek-themed slot is much more modern, as it was released in 2021. As such, it offers contemporary features like expanding symbols and free spins.
Released by Playtech in 2006, Ugga Bugga is one of the most popular best RTP slots at 99.07%. It comes with an African jungle theme and an engaging multi-spin feature.
From the description, you can guess that this is a pirate-themed slot. With it, you get a 98.6% RTP slot and low volatility. Plus, there are expanding wilds with bonus rounds offering up to 50 free spins.
These highest RTP slots are pretty rare, and I didn’t find them at most sweepstakes casinos. Nevertheless, it’s worth recognizing them.
I found many players asking about ways to boost the RTP of a slot during my reviews. If you’re also curious about that, the fact is that it’s not possible. You can’t increase the RTP of any slot. The percentage is locked in by the game’s provider, and no trick or hack can alter it.
For emphasis, all slots from legit developers use a Random Number Generator (RNG). This is basically a piece of software that spits out thousands of random numbers per second. Each figure is tied to a specific outcome on the reels.
When you hit the spin button, the RNG picks a number at that exact millisecond. That’s what decides whether you match symbols or not. Due to this setup, every spin is totally random and independent.
You can’t study the patterns or apply strategies to get more matching combinations. I’ve personally tried this and can confirm firsthand that it’s not reliable. What can you do, then? Well, simply pick the best RTP slots from the start.
RTP is crucial, but it’s not the only factor that affects the performance of a slot. Other aspects like volatility, bonus features, theme, multipliers, and play size also count. I’ve explained them below so you know what to check:
Also known as variance, volatility indicates the difficulty level of a slot and how often symbols hit. Personally, I consider RTP and volatility side by side when picking an online slot. With low-volatility titles, you get frequent but smaller hits. I find them ideal if you have a low GC or SC balance, or you simply want to play for longer.
On the other hand, high-volatility slots hit less often but offer larger potential multipliers. With medium-volatility titles, you get a balance of low and high. Ensure you check the game’s info or the developer’s website for the volatility rating, and choose based on your playing style.
I sometimes skip even the best RTP slots online if they don’t come with solid bonus features. That’s how critical this factor is, as the special elements make gameplay more exciting. Some can even increase the possibility of matching symbols, which affects the RTP.
Based on sessions, the bonus features vary from game to game. Providers and casinos usually use them as headliners when advertising their slots, so it shouldn’t be difficult to spot them. That said, these are the most popular ones to anticipate:
| Bonus feature | How it works |
|---|---|
| Wilds | Special symbols that can substitute regular ones to create more matching combinations. |
| Scatters | Symbols used to trigger special features beyond the base game, most especially bonus rounds. |
| Free spins | Extra spins without touching your GC or SC. You usually trigger them by landing scatter symbols. |
| Megaways | A dynamic reel setup that offers 117,649+ ways to match symbols. |
| Cascading reels | An engaging feature where matching symbols go off the reels for new ones to occupy their positions. This can cause extra hits. |
| Multipliers | Random values that can increase your GC or SC return by a set amount. |
If you ask me, a slot’s theme tells you what vibe to expect before you even take your first spin. This is natural, as the theme influences the visuals, sounds, and the overall storyline. Thankfully, it’s not easy to figure out: simply look at the preview or description of the slot.
Suppose it’s an Ancient Egypt theme. In that case, you’d expect symbols like pharaohs, pyramids, ankh, and hieroglyphs. The sound can be flutes, chanting priests, or desert winds. Meanwhile, a classic fruit slot will have 7s, bars, coins, and fruits with mechanical reel audios.
From the above, you can see how themes play a huge role in the overall experience. While having RTP in mind, ensure you pick a theme that piques your interest.
The maximum multiplier is the biggest hit a sweepstakes slot can drop. It’s often listed as a multiple of your play size (like 5,000x) or a fixed jackpot amount. If the maximum multiplier is 5,000x, and you hit it using 10 GC, you’ll receive 50,000 GC.
For many players, hitting the maximum multiplier in an online slot is an important target. As a result, they pick titles with huge values like 10,000x or more. I also aim for it, but note that it usually requires landing rare combos. Also, you don’t get free slots for real money online at sweepstakes casinos. If you hit the highest multiplier, you can only redeem real prizes if you were spinning using SC.
As you select the best RTP slots, check the minimum and maximum amount of GC and SC you can play per spin. That’s the play size, and it should accommodate your balance. Otherwise, you can’t play for long.
Take a 10 GC to 1,000 GC play size limit, for instance. If you have 10,000 GC in your balance, it means you can play 100 to 1,000 spins. Meanwhile, a 5 GC to 5,000 GC limit allows you to play 200 to 2,000 spins.
For this fact, I won’t say there’s a specific best range. However, lower is better when you’re playing with Sweepstakes Coins since they usually come in smaller amounts in bonuses. If you’re spinning with Gold Coins, you can target higher play size limits.
With the top RTP slots, you get ideal returns after spinning in the long term. This also means you can play more since you get back a higher amount of Gold Coins and Sweepstakes Coins. Besides, a good RTP means a low house edge, which works in your favor. That said, I believe the drawback is that the RTP doesn’t influence short-term results, unlike what some players think. You may not play a single slot long enough to truly benefit from its high RTP. To summarize, these are the upsides and downsides to know:
If you’re a consistent slot player, spinning titles with high RTP will provide better returns in the long run. However, remember that the RTP isn’t the only factor that affects your experience with an online slot. As I detailed in this guide, look into volatility, bonus features, and others. Also, don’t forget that the RTP doesn’t influence short-term results.
Overall, what’s important is that you use a legit site with games from trusted providers. Thankfully, I’ve outlined the top five sweepstakes casinos with the best RTP online slots. Pick one that catches your attention and consider signing up today.
The slots with the best RTP are those that offer at least 96%. You can find them at top US sweepstakes casinos like Real Prize, Stake.us, McLuck, High 5 Casino, and CrownCoins Casino.
Yes, a higher RTP is usually better, as it means you’ll get back more of your virtual currencies in the long run. That said, note that it doesn’t apply in the short term, and results from individual spins can significantly vary.
A 95% RTP means you can get back 95 GC or SC for every 100 you post on a sweepstakes casino slot. It’s a decent return to player featured in many games.
The average RTP for casino slots is 96%. Therefore, if a slot offers higher than 96%, it’s considered to be a high-RTP game. Conversely, if lower than 96%, it’s a low-RTP slot.
Slot RTP works by dividing the total number of returns over a long period by the total amount of plays. Generally, the higher the RTP, the more favorable a slot is to play.
