If you’ve spent any time researching online slots, you already know that not all games are created equal. Return to Player (RTP) — the theoretical percentage of wagered money a slot pays back over time — can swing from a stingy 88% to an eye-watering 99% depending on the title you choose. And when it comes to consistently high-RTP games, few developers have a track record like NetEnt.
Founded in Sweden in 1996, NetEnt (Net Entertainment) built its reputation on two things: gorgeous game design and unusually player-friendly math. While many modern studios chase volatility and flashy max-win figures, several classic NetEnt titles still sit among the highest-paying slots ever released — and they remain available at hundreds of licensed casinos today.
What Is RTP and Why Does It Matter?
RTP (Return to Player) is the percentage of all wagered money a slot is programmed to return to players over millions of spins. A slot with a 97% RTP theoretically pays back $97 for every $100 wagered — leaving the casino a 3% edge.
Three important caveats before we dive in:
- RTP is long-term math, not a session guarantee. Over a few hundred spins, anything can happen. RTP only converges over enormous sample sizes.
- Volatility matters just as much. Two slots with identical RTP can feel completely different. Low-volatility games pay small wins frequently; high-volatility games pay rarely but big.
- Casinos can offer reduced-RTP versions. Some operators license lower-RTP builds of popular slots. Always check the game’s info panel (the “i” button) at your specific casino before playing.
With that out of the way, here are the NetEnt slots with the best payout rates you can find.
- Mega Joker — 99% RTP
Volatility: High | Max Win: 2,000x | Released: 2013
Mega Joker isn’t just NetEnt’s highest-RTP slot — it’s one of the highest-RTP slots ever made by any developer. This retro fruit machine features a two-tier layout: a standard base game on the bottom reels and a Supermeter mode on top, where wins from the base game can be gambled at higher stakes.
Here’s the catch that separates casual players from sharp ones: the headline 99% RTP is only achievable when playing max bet and using the Supermeter strategically. Play at minimum stakes without engaging the Supermeter and the RTP drops to around 76.9% — a massive difference. The game also features a progressive jackpot that adds extra payout potential.
Why it ranks #1: No other widely available NetEnt slot comes close to 99%. If you understand the Supermeter mechanic, this is mathematically the best NetEnt game you can play.
Best for: Experienced players comfortable with max-bet strategy and classic slot gameplay.
- Jackpot 6000 — 98.8% RTP
Volatility: Medium-High | Max Win: 6,000 coins | Released: 2010
Another vintage-style machine, Jackpot 6000 recreates the feel of a Norwegian “Jackpot” pub slot from the 1980s. Like Mega Joker, it uses a Supermeter system — after any win, you can transfer your winnings into Supermeter mode at 20 coins per spin, where the top prize of 6,000 coins and mystery wins between 10 and 6,000 coins come into play.
The 98.8% RTP again assumes optimal play at maximum bet with smart Supermeter usage. There’s also a Heads or Tails gamble feature that is genuinely 50/50 — meaning it doesn’t erode your RTP, a rarity in gamble features.
Why it ranks #2: Near-Mega Joker payout rates with slightly simpler gameplay and a fair gamble feature.
Best for: Players who love old-school mechanics and want top-tier RTP without a progressive jackpot dependency.
- Blood Suckers — 98% RTP
Volatility: Low | Max Win: ~1,015x | Released: 2009
If Mega Joker and Jackpot 6000 require strategy to hit their advertised RTP, Blood Suckers gives you its full 98% RTP with no strings attached — every spin, every stake level. That’s why this gothic vampire slot has been a favorite of bonus-wagering players for over 15 years.
The game features 25 paylines, free spins with a 3x multiplier, and a Vampire Slaying bonus round where you stake coffins for instant cash prizes. Because volatility is low, wins land frequently, making it one of the most bankroll-friendly slots in existence.
Why it ranks #3: The highest unconditional RTP in the NetEnt catalog. No max-bet requirement, no strategy needed.
Best for: Bonus clearing, long sessions, and players who prefer steady wins over lottery-style variance.
- Kings of Chicago — 97.8% RTP
Volatility: Medium | Released: 2011
A genuinely unique hybrid, Kings of Chicago blends video poker with slot gameplay. Instead of matching fruit symbols, the five reels deal playing cards, and you’re paid for poker hands — three of a kind, straights, flushes, full houses, and the elusive royal flush.
The 1920s Prohibition-era theme (mobsters, tommy guns, jazz) wraps around a game where poker-style hand rankings replace traditional paylines. Free “deals” are triggered by scatter symbols, and all free-deal wins are doubled.
Why it ranks #4: A 97.8% RTP with medium volatility and gameplay depth you won’t find in a standard slot.
Best for: Poker fans and players bored of conventional reel mechanics.
- Devil’s Delight — 97.6% RTP
Volatility: Medium | Released: 2010
Darkly comic and criminally underrated, Devil’s Delight is a hell-themed slot featuring the Soul Reaper bonus, sticky wilds, and a Soul-O-Meter side mechanic that collects souls to trigger a bonus game with multipliers up to 5x.
The 97.6% RTP applies across all stake levels, and the medium volatility means the game strikes a nice balance — frequent enough wins to sustain a session, with bonus features capable of meaningful payouts.
Why it ranks #5: Excellent RTP paired with one of NetEnt’s more creative feature sets of its era.
Best for: Players who want high RTP with more feature variety than the classic fruit machines offer.
- Simsalabim — 97.5% RTP
Volatility: Medium | Released: 2010
A magician-themed slot with a top hat full of value. Simsalabim’s standout is its Rabbit-in-the-Hat bonus game, where picking rabbits from hats awards instant coin prizes — a feature that contributes heavily to the game’s 97.5% RTP. Free spins come with a 3x multiplier, and the wild-heavy reels keep base-game action lively.
Why it ranks #6: Rock-solid RTP, approachable mechanics, and a bonus round that regularly delivers.
Best for: Casual players who want strong math without needing to learn special strategies.
- Jack Hammer 2: Fishy Business — 97.1% RTP
Volatility: Low-Medium | Released: 2012
The sequel to NetEnt’s comic-book noir hit expands the grid to a massive 99 fixed paylines and introduces Random Wilds in the base game. The signature feature remains Sticky Win re-spins: any win freezes in place while the other reels re-spin, letting wins snowball into serious payouts.
Free spins can chain up to 20 at a time, and the low-to-medium volatility makes it forgiving on smaller bankrolls.
Why it ranks #7: A 97.1% RTP with genuinely fun cascading-style mechanics and great art direction.
Best for: Players who enjoy re-spin mechanics and comic-book aesthetics.
- Steam Tower — 97.04% RTP
Volatility: Medium-High | Max Win: ~2,000x | Released: 2015
A steampunk adventure where a grappling-hook hero climbs a tower to rescue a princess from a dragon. Landing stacked wilds triggers 10 free spins, and every wild during the feature moves you up the tower — with multipliers climbing from 2x to a maximum of 7x at the top floor.
Steam Tower is the most volatile game in our top eight, but the climbing-multiplier free spins give it real ceiling, and 97.04% RTP is exceptional for a feature-rich video slot.
Why it ranks #8: High RTP and high win potential — a combination that’s genuinely rare.
Best for: Players who want top-tier RTP but crave bigger, more dramatic wins.
- Blood Suckers II — 96.94% RTP
Volatility: Low-Medium | Max Win: ~1,298x | Released: 2017
The sequel to the legendary original, Blood Suckers II follows vampire heiress Amilia on a treasure hunt. It keeps the franchise’s player-friendly math (96.94% RTP) while adding modern features: Scatter Shot random wilds, free spins with escalating multipliers up to 3x, and the Hidden Treasure bonus game with a top prize of 1,298x your stake.
It’s slightly more volatile than the original, trading a fraction of RTP for higher payout potential and sharper visuals.
Why it ranks #9: Nearly 97% RTP with modern production values and a bigger max win than its predecessor.
Best for: Fans of the original who want the same DNA with more excitement.
- Dead or Alive — 96.82% RTP
Volatility: Very High | Max Win: 12,000x (theoretical) | Released: 2009
A cult classic and arguably the most famous high-volatility slot ever made. Dead or Alive’s Wild West free spins feature — with sticky wilds across all five reels — is capable of legendary payouts when a full wild line lands. Streamers and high-stakes players have chased its max-win screens for over a decade.
At 96.82%, its RTP comfortably beats the industry average of roughly 96%, but be warned: the extreme volatility means long dry spells are normal. Its sequel, Dead or Alive 2 (96.8% RTP), offers even higher potential (over 100,000x) and is worth a look for volatility lovers.
Why it ranks #10: Above-average RTP combined with iconic, life-changing payout potential.
Best for: High-volatility enthusiasts with disciplined bankroll management.

How We Ranked These Slots (Our Methodology)
Transparency matters, so here’s exactly how this list was built:
- Official RTP figures were taken from NetEnt’s published game specifications. Where RTP varies by bet strategy (Mega Joker, Jackpot 6000), we’ve disclosed the conditions required to reach the maximum figure.
- Availability was considered — every slot on this list is still live at major licensed casinos, unlike some retired high-RTP titles.
- Ties were broken by payout structure and player value: volatility balance, feature quality, and max-win potential.
We deliberately excluded jackpot slots like Mega Fortune and Divine Fortune from the main rankings, because their base-game RTP (around 96%) understates total return only when the progressive is factored in — an apples-to-oranges comparison.
Tips for Maximizing Your Payouts on NetEnt Slots
- Verify the RTP at your casino. Open the game’s paytable/info screen and confirm the RTP matches the figures above. Some operators run reduced-RTP versions (e.g., 94% builds of popular titles).
- Match volatility to your bankroll. Low-volatility games like Blood Suckers suit small budgets and long sessions; Dead or Alive demands a deep bankroll and patience.
- Learn the Supermeter games properly. Mega Joker and Jackpot 6000 only reach their headline RTP with max-bet, optimal play. Practice in demo mode first.
- Use bonuses wisely. High-RTP, low-volatility slots are ideal for clearing wagering requirements — though many casinos restrict or weight these games, so read the bonus terms.
- Set limits before you spin. RTP is a long-run average, not a promise. Decide your loss limit and session length in advance, and stick to both.
FAQs
What is the highest RTP NetEnt slot? Mega Joker, at up to 99% RTP — but only when playing max bet with optimal Supermeter strategy. For the highest unconditional RTP, Blood Suckers at 98% is the best choice.
Are these RTP figures guaranteed? No. RTP is a theoretical long-term average calculated over millions of spins. Individual sessions can pay far more or far less. Additionally, some casinos license lower-RTP versions of these games, so always check in-game.
Are NetEnt slots fair? Yes. NetEnt games are certified by independent testing agencies (such as eCOGRA and iTech Labs) and licensed by regulators including the Malta Gaming Authority and UK Gambling Commission. Since 2020, NetEnt has operated under Evolution, one of the industry’s largest publicly traded companies.
Is a 97% RTP slot better than a 96% slot? Mathematically, yes — over the long run, a 1% RTP difference doubles from a 3% to 4% house edge in relative terms. But volatility, bet size, and session length affect your short-term experience far more than a single RTP point.
Can I play these slots for free? Most licensed casinos offer demo versions of NetEnt slots, which is the smartest way to learn mechanics like the Supermeter before wagering real money.
Final Verdict
NetEnt’s classic catalog remains the gold standard for player-friendly slot math. If pure RTP is your priority, Mega Joker (99%) and Jackpot 6000 (98.8%) are unbeatable — provided you play them correctly. For a no-strategy, set-and-forget option, Blood Suckers (98%) is arguably the best-value slot ever released. And if you want payout potential alongside strong RTP, Steam Tower and Dead or Alive deliver excitement the vintage machines can’t match.
Whichever you choose, remember the golden rule: RTP tells you the game’s math, but discipline determines your experience. Play at licensed casinos, verify RTP in the game panel, and treat every session as entertainment first.
