Top sweepstakes casinos with the best RTP social slot machines

Before I start detailing the sites, I’ll first explain how sweepstakes casinos work. Simply put, the sites operate with virtual currencies known as Gold Coins (GC) and Sweepstakes Coins (SC). Neither of the two has any monetary value, and you use them to play slots and other available games.

The difference is that after playing, SC can be redeemed for real prizes if you meet all requirements. On the other hand, GC are only for entertainment, so you only get more of the virtual currency from your sessions.

With that covered, check out my top sweepstakes casinos with high RTP online slots below:

What does RTP mean in slots?

RTP stands for Return to Player, and it’s simply a percentage that tells you how much a slot game is designed to give back over time. For example, if a sweepstakes casino slot has a 96% RTP, it means that, on average, it’ll return 96 GC/SC for every 100 played.

I must stress the over the long run aspect because RTP doesn’t apply to single sessions. Instead, it’s calculated over thousands and even millions of spins. As a result, your results can vary by a wide margin in short-term play. Besides, all slot outcomes are random, even in a high RTP game.

How RTP affects the house edge

The house edge or advantage indicates the cut the sweepstakes casino keeps over time. Interestingly, the RTP works in reverse to show the percentage. A slot with 96% RTP has a 4% house edge, while one with a 95% RTP features a 5% house edge.

To illustrate, if you play 100 GC in the long run on a 96% RTP slot, the sweepstakes casino will keep 4 GC. In return, you receive 96 GC. Clearly, the higher the RTP, the lower the house edge, and the more player-friendly the game is in theory. That’s why expert players like me go for the highest RTP sweepstakes casino slot machines.

Why RTP matters

In my experience, RTP gives you a baseline idea of whether a game is fair. It doesn’t guarantee short-term results, but it’ll help you compare multiple slots on a level playing field. Let’s say you have two similar titles, one with 94% RTP and the other with 97%. Ideally, you’ll pick the higher RTP slot simply because it gives you a better theoretical return since it reduces the house edge.

RTP vs volatility

Besides the RTP, volatility is another key feature I consider when selecting a slot. Although both are often mentioned together, they measure completely different things.

Remember, RTP tells you how much a slot will give back over the long run, and the percentage depends on millions of spins. On the other hand, volatility indicates how often you match symbols and the size of the multipliers.

With a high volatility slot, you won’t hit symbols too frequently. However, each time you do, the multiplier will likely be big. Conversely, a low volatility slot will match symbols more often but with smaller multipliers. There’s also medium volatility, which offers a balance between high and low.

The key point is that a high RTP slot doesn’t mean you’ll land symbols frequently. In that aspect, the volatility is what counts. Make sure you look into and compare both when deciding on reels to spin.

RTP vs hit rate

When checking slot metrics, the hit rate is another statistic you’ll come across. It differs from RTP, as the hit rate measures how many spins it takes to land a matching combination. Hence, if the percentage is 40%, it means about 4 in every 10 spins will hit matching symbols on the reels.

Like RTP, the hit rate is also theoretical and isn’t always consistent in the short term. For this reason, it’s not an overly popular metric among players. I rely more on the volatility than the hit rate to know what to expect with each spin.

Yes, the high RTP slots at my best sweepstakes casinos are legal. All the 4 sites listed in the reviews above are fully compliant with all the sweepstakes regulations. This allows them to operate in most US states, and it allows them to offer all of these high RTP slots.

While sweepstakes casinos are legit in the US, note that the sites are unavailable in certain states. I noted these during my reviews, and it’s because of varying local laws. Therefore, before joining any sweepstakes casino on my list, first confirm that it’s available in your location.

Highest sweepstakes slot machine RTP list

I carried out detailed research to spot some of the sweepstakes slots with the highest RTPs in history. These are the titles I found:

SlotRTP
Goblin’s Cave99.32%
Ugga Bugga99.07%
Mega Joker99.00%
Ooh Aah Dracula99.00%
Book of 9999.00%
1429 Uncharted Seas98.60%
Blood Suckers98.00%
Money Cart 298.00%
White Rabbit Megaways97.77%
Big Bad Wolf97.35%

Based on my checks, the above games are not too common at sweepstakes casinos. Nevertheless, sweepstakes slots with a 96% RTP or above are still decent and ideal if you want higher returns on your GC and SC.

How to find the highest RTP sweepstakes casino slot machines

Some players skip checking the RTP for online slots because they don’t know how to look for it. Well, it shouldn’t be complicated, and these are the different methods I use:

🎰 Check the Game Info Section

Most slots have an info or help menu when you launch, indicated by an “i” or a gear icon. That’s where developers list all features of the game, including the symbols, special elements, bonus rounds, and the RTP. Usually, I find the best RTP slot machines at a sweepstakes casino by scrolling to the bottom of the info section.

If the game has a bonus round, you’ll likely see two RTPs: one for the base game and another for the bonus round. Now, if you don’t find the RTP in the help section of the slot, you can check the provider’s website directly.

🔍 Look for Reputable Developers

Some software providers are renowned for creating high RTP slots. I can mention names like NetEnt, Play’n GO, Red Tiger, and Pragmatic Play, which often set the rate above 96%. Hence, if you go for online slots from these brands, there’s a higher probability of getting a high RTP.

📂 Use Sweepstakes Casino Filters or Categories

At top sweepstakes casino sites, slots are grouped in different categories. I’ve seen sections labeled High RTP on some sites, but it’s pretty rare. What’s more common are Player Favorites or Featured Slots. These favorite or featured titles are what other users are playing.

If you ask me, many players won’t be spinning the same reels unless the slots have something notable to offer. It may have high RTPs, so consider checking them out. Filter the favorite or featured games and do a quick search on their RTPs to confirm.

🚫 Skip Mystery Games

I avoid assuming a slot has high RTP without checking. If it’s not listed, I treat it as average at best. That’s because most providers will tell the RTP upfront if the rate is high since it’ll interest players to spin. Therefore, if a slot or developer is mysterious about the return rate, I skip it.

⚠️ Watch Out for Adjustable RTPs

My gaming experience over the years has shown me that some Vegas-style casino games have multiple RTP settings. For instance, you can find one slot having 90%, 94%, or 96%, depending on how the sweepstakes casino configures them. A trusted brand will usually stick with the higher versions, but perform your check to be sure.

Debunking myths about RTPs

Owing to its popularity and importance, RTP is one of the most misunderstood stats among slot players. Many myths surround it, and believing them can lead to wrong expectations. To set the record straight, I’ve debunked some myths about the highest RTP sweepstakes casino slot machines to know before playing:

Myth 1: High RTP means you’ll hit more often

When some players hear high Return to Player, they take it that they’ll match symbols frequently while they spin. However, that’s not the case, as the RTP only returns more over the long run. What actually determines how often you match symbols is volatility, as I explained.

I’ve played high RTP sweepstakes slots that are also highly volatile. Hence, while the games will potentially return more GC/SC over time, I didn’t match symbols regularly in the short term.

Myth 2: RTP is a guarantee

The RTP isn’t a promise in any way; it’s only a long-term average. A 96% RTP means that the game is designed to return 96 GC/SC for every 100 you play over a million spins. However, that doesn’t imply you’ll get back 96 GC/SC every session. It’s important to recognize this myth so you have realistic expectations.

Myth 3: All versions of a slot have the same RTP

It’s easy to assume that the same slot always offers the same RTP regardless of the sweepstakes casino. However, that’s not true. Software developers often release multiple versions of a slot with different RTP settings. Then, it’s up to the sweepstakes casino to decide which rate it wants to offer.

Two sweepstakes casinos can offer the same slot title but with different RTPs. For instance, you can play Epic Joker at Crown Coins Casino with a 97% RTP and get 96% on another site. This variance can result from differing sweepstakes rules & regulations, so it’s always best to cross-check.

Myth 4: RTP changes based on time of day or player behavior

The concept of hot and cold slots is one of the biggest myths when it comes to sweepstakes casinos. I’ve come across people who believe slots go hot during busy hours, meaning players match more symbols. That way, they’ll want to spin more.

Furthermore, there’s the belief that if a slot hasn’t hit for a while, it’s due for one. Also, if players have scored many matching combinations, the game will go cold and offer fewer hits. All of these are myths.

The RTP is built into the game and doesn’t change based on time, behavior, or recent results. In other words, the slot itself doesn’t record whether you match symbols or not. It simply offers random results on every spin, and the hot/cold concept is human bias.

Can you increase a slot’s Return to Player rate?

Simply put, you can’t increase a slot’s RTP. The percentage is hard-coded into the game’s design and is also linked to the math model. Changing the RTP requires reprogramming the game itself, and only the developer can do that.

If you play at my top sweepstakes sites with the highest RTP sweepstakes casino slot machines, you get titles from only legit developers. Each one uses a certified Random Number Generator (RNG), which influences the result of every spin. The RNG constantly scans through number combinations, even when you’re not playing.

When you press Spin, it instantly selects a random number to determine the outcome. This selection is entirely based on probability and doesn’t take past or future results into account. As such, increasing RTP isn’t one of the tips to win in sweepstakes casinos because it’s impossible.

Pros and cons of sweepstakes slot machines with the highest RTP

The benefits of playing high RTP slots are noteworthy. From my standpoint, I appreciate the games for offering a low house edge while allowing more returns in the long run. If you play over time, you can stretch your GC and SC for more play time at sweepstakes casinos.

However, the fact that the RTP doesn’t play a role in short-term outcomes is a potential drawback. Most players actually expect that, since they’ll likely not play thousands or millions of spins on a specific slot. Nevertheless, for those who do, a high RTP is ideal.

Here’s my summary of the pros and cons of the highest RTP sweepstakes casino slot machines:

Pros and Cons
Pros and Cons
  • Allows a lower house edge

Conclusion – Spin the highest RTP slots at top sweepstakes casinos

RTP might not be everything, but it’s one of the key stats I always check before spinning at a sweepstakes casino. The rate won’t predict your next spin or short-term results, but it’ll provide a glimpse of how a game will perform over time. Combine the percentage with volatility and hit rate, and it becomes easier to select a slot that fits your strategy.
