It’s time to get this off my chest! There are plenty of great studios out there making innovative, entertaining slots, but there are also some that I’d rather skip. Whether it’s because of low RTPs, or forced bonus buys, or AI art – the list goes on.
So let’s get into my choices below. Also, bear in mind that it’s up to you whether you want to avoid these developers completely, but this page will help you feel better informed on certain points before you part with your hard-earned GC and SC at your sweepstakes casino of choice.
Providers With Low RTPs
First, let’s look at Return To Player, or RTP. This is a very important metric to track, as it tells you how much you’re likely to win back/lose over time. The RTP of a game is chosen by the social casino in question, but only from the configurations made available by the game developer, and there are certainly studios that have lower RTPs than others.
KA Gaming
This won’t be the first entry on this page for KA Gaming. The RTPs for its games are generally not available within the game interface, but we can use third-party sites to check. If we do, we find slots like Olympus Gods and Crazy Blackbeard with an upper RTP of 90%, but in reality casinos often pick the lower available RTPs, and we’ve heard reports of levels as low as 80% – that’s incredibly poor!
Spinomenal
Unfortunately it’s a similar story for Spinomenal, which has multiple slots in its roster that start as low as 90%. This includes Story of Gaia, or even Gangster’s Gold at 89.1% with a measly max win of 1,000x! If you know the stats of these games, I’m not sure why you’d ever play them, unless you like losing coins fast.
Clawbuster
A third studio in the infamous 90% club is Clawbuster. Slots like 3 Claws of Leprechaun and 4 Super Hot Pinatas start from this low level, offering a very paltry return on your reel spins, especially when we consider many casinos will take the even lower options. These slots I mention aren’t old either – they’ve been released in 2026, which is a real shame to see.
Providers With Low Quality or Rehashed Games
Unfortunately, there are so many studios I could include in this section – the slots space is awash with providers that copy themes and mechanics that have been done a million times before. Often the graphics can feel dated, or they use AI artwork too.
For example, we’ve seen an epidemic of ‘3 pot’ games and this concept is starting to feel really monotonous now. Here at SweepsKings we like to see games that push slots forward, rather than retread the same ground over and over.
MrSlotty
MrSlotty hasn’t released anything for a while now, but its games are still available at some of the smaller sweepstakes casinos. Even at the time of release, these slots looked very garish and shaky. I’m talking about titles like Super Dragons Fire and Aztec Pyramids, where the RTP of 94% doesn’t inspire much hope either.
Edge Labs
It’s a similar story with Edge Labs. Even the newer titles like Liberty Rising feel dated and pull from mechanics and themes we’ve seen too many times before (hold & win, jackpots etc.). There’s also an obvious use of AI imagery, which just looks completely cheap to me.
Funky Games
The name for this studio sounds kind of fun, but unfortunately I’ve never really enjoyed its games like Panther Moon or Blazing 777. The graphics and general user interfaces look cheap and dated – like something that would have been released 10 years prior.
The gameplay is also derivative, with basic payline mechanics and bonus features that just don’t excite most modern players. You might find low RTPs and max wins too. Overall, I just don’t see any reason to play these games when you have plenty of other amazing options.
Providers That Keep Repeating the Same Games
This section is a little different from the previous one. Sometimes a provider will happen upon a great game mechanic or style, then proceed to beat players over the head with it for years on end, to the point where it starts to feel boring.
One main example of this over the last few years was probably the Big Bass series, but since Pragmatic Play no longer supplies the sweeps space, let’s look at some different examples.
Betsoft
When I think of Betsoft, I think of 4 or 5-tier jackpots, coins and collect symbols, hold & win rounds, and the aforementioned ‘3 pot’ games. I’m not saying that every single game from this studio features the same mechanics, but many of them do – to the point where it starts to feel like the same game dressed up in a different theme with every new release.
But the other problem here is that this company seems to be leaning very heavily on AI art, so each title also has the same look and atmosphere. It’s like Betsoft is simply a conveyor belt for slot content rather than an artful studio these days.
Inbet Games
Here’s a studio that seems firmly stuck in the traditional/retro casino niche, with a glut of slots like Epic Hot, Flaming Crown, Hot Clover, and Blazing Fruits. All of these games feel quite old, playing up that garish fruit machine aesthetic that’s all too common.
Sometimes the themes diverge a little, like with Panda Joy or Special Dragon Bonus, but the gameplay barely moves beyond traditional paylines and one basic extra feature, possibly with the ‘Risk or Take‘ feature thrown in. The grids are usually 5×3 or 5×4 too, adding to that old-school feel. I just wish studios like Inbet would think outside the box a bit more.
Providers With Poor RTP Transparency
One of my bugbears is when a supplier doesn’t display the RTP within the game’s UI. The better casinos will display the RTP for every game in the lobby, helping you make an informed decision before you even load anything up. But if neither the casino nor the supplier tells you the RTP – which can sometimes happen – you’re left guessing, and that’s not good enough.
JILI (TaDa Gaming)
As fun as JILI games can be, it’s usually impossible to find reliable RTP values for them. Most other suppliers will list this number in the game rules/info section of the game’s UI, but there’s often nothing listed in JILI’s slots and fishing games like Agent Ace and Jackpot Fishing.
What makes it all the more strange is that RTP as a concept is mentioned, but no figure is ever shown. On top of that, I have a feeling that JILI’s games actually have very good RTPs! Figures online suggest 97% for a lot of titles, so it’d be much better for everyone if the developer put the questions to rest.
Acewin
While it’s never been confirmed, there’s speculation that Acewin could be an alias used by JILI, and the fact that Acewin doesn’t offer up RTPs either strengthens that theory. You’ll find rules and available paylines in the game info section, but no RTP, leaving players in the dark.
It’s a shame, because some slot clones like Mummy Mia and Puff & Puff can actually be a lot of fun, bringing fun styles from land-based casinos to the digital world.
KA Gaming
KA Gaming makes a second appearance on this list for its lack of visible RTPs within game interfaces. I can never find the rates when I’m playing at sweepstakes casinos and have to spend time looking elsewhere on third-party sites, which is far from ideal – it’s the developer’s responsibility to make this information easily available to players. Otherwise, it’s difficult to know exactly what you’re playing with, and that can raise questions.
Even on the third-party sites, there are plenty of KA Gaming titles with no RTP listed at all, leaving players with little idea of what return they’re actually playing for.
Providers That Push You Into Bonus Buys
I have a love/hate relationship with bonus buys. In one way, they allow you to skip straight to the fun part, but they also remove much of the light and shade from a game. Sometimes the bonus features are rewarding precisely because you’ve had to play through the base game to get there, and buying them over and over can make the whole thing feel a bit like cheating.
I now feel that some studios are using ante bets and bonus buys as an easy way to make unbalanced games – there’s an art to a slot that’s well-balanced between the base game and bonuses, and this is being lost somewhat. Also, the elephant in the room is that it’s usually not great for the player’s wallet – bonus buys up the volatility considerably, creating fast and loose spending. This clearly benefits the casino and developer more than the player.
It’s not that bonus buys are bad per se, it’s that I wish they weren’t relied as much as they are nowadays.
3 Oaks
3 Oaks has a lot of games that seem to revolve almost entirely around hold & win rounds. In fact, at the time of writing, its last 4 games (Coin Up Volcano, Grand, 4 Fortune Clovers, and Super Hotfire Diamonds) are all hold & win. Some, like 3 Coin Volcanoes, don’t even offer base-game wins at all – it’s all about hitting the bonus round, which is, of course, available to buy.
On top of all this, there’s the discourse around the ‘change bet’ button being positioned too close to the ‘spin’ button on mobile, which we covered recently.
Playson
Playson treads a similar path with 3 out of its newest 4 releases being hold & win (4 Supershiny Diamonds, Clover Smash!, 4 Chili Pots), and these games usually have 4-tier jackpots too.
In fact, both of these suppliers could have been included in the category of studios that repeat themselves from earlier – but what we’re really highlighting here is how the games are pretty dull affairs in the base game, with a huge emphasis on the bonus round. This can lead to rapid purchasing of bonus rounds for 60x your usual spin amount or more.
Which Sweepstakes Casino Providers Are Actually Good?
The developers that are in my good books at the moment are those that avoid all of the issues above, creating well-balanced, innovative games with excellent production values, plus all the info you could ever need within the game’s UI.
Some of my recent favorite slots come from:
- Print Studios (Deck of Divinity, 12 Burning Baseballs, Uncle Profit)
- Shady Lady (Suck, Laced, Sew)
- Peter & Sons (Bloody Mary: Pray for Prey, Lucky Caiman, Greedy Alice 2: Bigger Bites)
- Relax Gaming (Midnight Marauder – ClusterBreaker, Guitar Quest, Snake Arena 2)
- Evolution/NetEnt (newer releases like Godbreaker and Dead or Alive 3: Wanted)
In my opinion, players can generally be confident they’ll get something top class from these providers! They’re the studios I’d look to first when I want a slot that feels original, well-made, and worth spending time on. Some solid social casinos that offer these suppliers include Stake.us, Modo.us, Mega Bonanza, and Jackpota.
