NetEnt slots explained

What NetEnt slots are and who is behind them

NetEnt is one of the oldest names in online slot design. Founded in 1996 and headquartered in Stockholm, it built many of the games that UK players still see near the top of casino lobbies. Since December 2020 it has belonged to Evolution, the live-casino group, which also owns Red Tiger, Big Time Gaming and Nolimit City.

Like every studio in our slot providers directory, NetEnt writes the game software and supplies it to licensed casinos; it does not hold player accounts. That split matters when something goes wrong: the casino is responsible for your balance and any complaint, while the studio is responsible for how the game behaves.

NetEnt’s catalogue is wide in style. It spans a three-reel fruit game with a Supermeter, low-volatility ten-line classics, cascading adventure games, branded titles such as Narcos and Jumanji, and progressive jackpots linked across many casinos.

Three NetEnt slot mechanics that spread across the industry

Avalanche reels

In Gonzo’s Quest, symbols fall into place rather than spin. A winning combination crumbles away, the symbols above drop down, and new ones fill the gaps, so one paid spin can produce several wins. NetEnt calls this an avalanche; other studios call it a tumble or cascade, and our guide to cascading reels shows a worked example grid. In Gonzo’s Quest each consecutive avalanche raises a multiplier, which is why chains matter more than single hits.

Expanding wilds

Starburst’s wild appears only on the middle three reels, expands to fill the whole reel and holds in place for a respin. Its ten lines pay both left to right and right to left, which lifts the number of ways a given screen can pay without changing the stake. Our page on expanding wilds explains how that changes the hit rate.

Linked twin reels

Twin Spin starts each spin with two adjacent reels showing identical symbols, and the link can grow to five reels. With 243 ways to win, matching reels raise the chance of a multi-way payout. The idea later moved into Twin Spin Megaways, released in November 2020, with up to 117,649 ways.

Best-known NetEnt slots: published RTP, volatility and max win

Each game has its own page: Starburst, Gonzo’s Quest, Twin Spin, Blood Suckers and Dead or Alive 2. The spread is the point. Starburst caps out at 500× and pays small amounts often, while Dead or Alive 2 can reach 111,111× but may go hundreds of spins without a notable return.

NetEnt jackpot slots and why their RTP looks different

NetEnt’s progressive games, including Mega Fortune (2009), Hall of Gods (2013) and Divine Fortune (January 2017), feed part of every stake into a shared prize pool. The published RTP of these games includes that contribution. Divine Fortune’s 96.59% is a good example: published analysis puts about 4.07 percentage points of it into the Mega jackpot, which leaves about 92.52% for the regular game.

In practice, a player who never wins the top jackpot experiences something closer to the lower figure. The jackpot is a very rare outcome, so most of the jackpot share of the RTP is paid to a tiny number of players. Our explainer on how slot jackpots are funded walks through the maths, and our guide to progressive jackpot slot machines compares the main networks.

Mega Fortune is listed at about 96% to 96.6% and Hall of Gods at about 95.5%, both including the jackpot share. Treat those as total figures, not the return from ordinary wins.

High-RTP NetEnt slots: Blood Suckers and Mega Joker

Two NetEnt games stand out for their published return. Blood Suckers lists 98.00%, and Mega Joker lists up to 99%, but only at the top stake while playing the Supermeter reels, a fruit-machine style feature. At lower stakes or outside the Supermeter the return is lower, so the headline figure applies to a specific way of playing.

A higher RTP lowers the average cost but does not make a win more likely in any one session. Whether high RTP slots are better is a fair question, and the short answer is that volatility often shapes a session more than a one-point difference in RTP.

NetEnt sequels, Megaways remakes and how the maths moved

Many NetEnt hits have follow-ups, and comparing them shows how the studio’s maths has drifted towards higher ceilings.

• Starburst (500×) became Starburst XXXtreme, high volatility with a 200,000× cap, and later Starburst Galaxy (2024), a 5×5 grid expanding to 7×7 with a 25,000× cap.
• Gonzo’s Quest (2,500×) became Gonzo’s Quest 2 (2025), high volatility with up to 262,144 ways and a 15,825× cap.
• Dead or Alive (9 paylines, high volatility) became Dead or Alive 2, with a 111,111× cap.
• Blood Suckers became Blood Suckers 2 (2017), at 96.94% with a 1,298× cap and a pick bonus.
• Twin Spin and Divine Fortune both gained Megaways versions in 2020, licensing the mechanic explained in our Megaways slot machines guide.

Several newer titles publish lower-RTP versions alongside the default. Gonzo’s Quest 2, for example, also exists at 94.15% and 92.13%.

NetEnt max wins at UK stake limits

Online slot stakes in Great Britain are capped at £5 a spin for players aged 25 and over and £2 a spin for those aged 18 to 24; the dates are on our online slot stake limits page. Here is what each published cap means in pounds.

The biggest caps sit on the most volatile games, and reaching them is extremely rare. Some casinos also apply a cash limit per spin or per bonus; check the casino’s terms and the game rules.

Evolution ownership and NetEnt’s UK licensing

Evolution completed its purchase of NetEnt in December 2020, adding a slot catalogue to a business built on live dealer games. The Evolution group website (opens in a new tab) now presents NetEnt alongside its other studios.

Every game supplied to Great Britain must meet the Gambling Commission’s technical standards, and the casino must hold a Commission operating licence. You can check any licence holder on the Gambling Commission’s register of gambling businesses (opens in a new tab). In July 2026 the Commission published a £4.75 million settlement with Evolution Malta Holding Limited after the group’s games appeared on unlicensed websites accessible in Great Britain; the Commission’s announcement (opens in a new tab) refers to Evolution’s games generally and does not single out NetEnt titles.

For players, the lesson is to play only at casinos with a UK licence. Games found on unlicensed sites carry none of the protections described in our guide to the Gambling Commission and slots.

How to tell which version of a NetEnt slot you’re playing

Because some NetEnt games ship with several RTP settings, the same title can cost different amounts at different casinos. These steps find the figure that applies.

1. Open the game and wait for the base screen to load.
2. Select the menu, then the paytable or game rules tab.
3. Find the line stating the theoretical return to player; NetEnt usually places it in the rules text.
4. For jackpot games, check whether the figure says it includes the jackpot contribution.
5. Compare it with the default figure in the tables above; a lower number means a lower setting.

NetEnt slot myths worth clearing up

• ‘Starburst pays both ways, so it pays twice as much.’ Paying both ways creates more winning combinations, but the paytable values are set so the published RTP is still 96.09%.
• ‘Mega Joker returns 99% whatever you bet.’ The top figure applies only at the highest stake with the Supermeter in play.
• ‘An avalanche chain means the next spin will be good.’ Each new spin is a fresh RNG result; the chain ends when no new win forms.
• ‘A big jackpot is about to drop.’ Unless a game states a must-drop point, a progressive is won at random, and its size tells you nothing about timing.

These ideas are common across all studios, and our guide to slot machine myths tackles the rest.

Where to play NetEnt slots online in the UK

You will find NetEnt titles at most large British casinos, yet ranges are reshuffled regularly and we can’t vouch for any single lobby. Type the game’s name into the search at Coral, Ladbrokes or PlayOJO to check.

None of the offers below is tied to NetEnt. Coral gives 100 free spins at 10p each on selected games when a new customer deposits and bets £10 on slots; Ladbrokes gives up to 500 free spins, 50 a day for 10 days at 10p each, after a £10 spend on slots; and PlayOJO gives 80 no-wagering free spins on Big Bass Bonanza with a first deposit of at least £10. All are for new customers aged 18+, and terms apply.
