The Lightning Wild, and what it does to 20 paylines

A wild that lands on reel 3 of Frankenstein does not stay on reel 3. NetEnt built the Lightning Wild to spread sideways, turning two or more adjacent positions wild across reels 2, 3 and 4, so one symbol can rewrite several of the 20 paylines in the same spin. That is the mechanic the game is famous for and the one every review page describes as atmosphere instead of maths. Frankenstein Slots is the official casino of that slot, and the page you are reading starts with the mechanic because it decides how the other numbers behave.

The specification is short and it is checked. Frankenstein runs a 5x3 grid with 20 adjustable paylines, returns 96.6%, sits at medium volatility and stops at 1,750x the stake, which is €175,000 when the €100 maximum bet is in play. Stakes open at €0.20, coin values run from €0.01 to €0.50, and bet levels from 1 to 10. Two wrong figures follow this game around the web, one that rounds the return up by a tenth of a point and one that inflates the ceiling more than twentyfold, and dividing €175,000 by the €100 top bet settles the second of them in a line.

Three or more Windmill scatters anywhere on the reels award 10 Burning Mill free spins. Inside that round the Lightning Wild is replaced by the Fire Wild, which is guaranteed on every single free spin and spreads across reels 2 to 4 the same way. Multiplier icons drop on reel 5 during the round and lift line wins by x2 up to x5. Two more scatters extend the round by 5 spins and three more by 10, so a warm sequence can run well past the opening ten.

Frankenstein and the machines around it

Frankenstein is the headline: 5 reels, 3 rows, 20 adjustable paylines, 96.6% RTP, medium volatility and a 1,750x cap worth €175,000 at the €100 maximum bet. The Gothic shelf next to it holds Dracula at 96.58% and Creature from the Black Lagoon at 96.50%, both NetEnt, both built on the same monochrome art direction. If you want the return figures rather than the theme, Mega Joker runs up to 99%, Starmania sits at 97.87% and White Rabbit Megaways at 97.72%.

Frankenstein and the machines around it
Game	Studio	RTP
Frankenstein	NetEnt	96.6%
Dracula	NetEnt	96.58%
Creature from the Black Lagoon	NetEnt	96.50%
Book of Dead	Play'n GO	96.21%
Starburst	NetEnt	96.09%
White Rabbit Megaways	Big Time Gaming	97.72%

The artwork comes from the 1931 Universal picture. NetEnt developed the game in association with Universal Pictures and released it on 23 April 2015, dressing the reels in a stone-walled laboratory, a gurney, laboratory glassware and the windmill that burns in the film's final reel. The Monster, Fritz, Dr Frankenstein and the jarred brain hold the premium positions, with A, K, Q, J and 10 carrying the low pays. There is no gamble button and no progressive pool on this machine, which is why the 1,750x cap is a fixed ceiling rather than a headline that moves.

Frankenstein Slots opens the account side with a flat package: 100% on the first deposit up to €500, plus 200 free spins on Frankenstein credited 40 a day across five days. Wagering is 35x on deposit plus bonus, the minimum qualifying deposit is €20, and the balance stays live for 7 days from credit. Around the headline game the lobby carries NetEnt, Evolution, Red Tiger, Play'n GO, Pragmatic Play, Yggdrasil, Relax Gaming, Quickspin, Thunderkick, NoLimit City, Push Gaming and Hacksaw Gaming.

Microgaming built a Frankenstein of its own. So did KA Gaming, while RubyPlay shipped Dr Frankenstein, Nucleus has Freaky Frankenstein, Blueprint runs Frankenstein's Fortune and Light and Wonder still keeps a land-based cabinet on casino floors. Sorting the NetEnt release out of that pile takes three readings from the tile: 20 paylines, a 96.6% return and the linked Lightning Wild on reels 2 to 4. A tile that shows a different grid or a different return belongs to somebody else's game.

Studios behind the lobby

NetEnt is the reason this site exists, and Evolution now owns the studio that built Frankenstein back in 2015. The lobby around the headline title runs on twelve studios: NetEnt, Evolution, Red Tiger, Play'n GO, Pragmatic Play, Yggdrasil, Relax Gaming, Quickspin, Thunderkick, NoLimit City, Push Gaming and Hacksaw Gaming.

NetEnt	Cinematic slots and Gothic licences	Frankenstein 96.6%, Dracula 96.58%, Creature from the Black Lagoon 96.50%, Starburst 96.09%

Evolution tables

Evolution supplies the live floor, which matters here because Evolution has owned NetEnt since 2020. Crazy Time, Lightning Roulette, Monopoly Live and Dream Catcher run from its studios with dealers on camera and stakes that start well below the €100 that Frankenstein allows on a single spin.

The Frankenstein Slots welcome package

The first deposit is matched 100% up to €500 and brings 200 free spins on Frankenstein by NetEnt, credited 40 a day over five days. Wagering is 35x on deposit plus bonus, the qualifying deposit starts at €20, and the package expires 7 days after it is credited. Slots carry the wagering, and the free spins run on the headline game at its 96.6% return.

Game	Slots, with the 200 free spins fixed to Frankenstein by NetEnt

A €100 deposit takes the match to €200 in play, and 35x on deposit plus bonus means €7,000 of slot wagering before the balance converts.
The 200 free spins arrive in batches of 40 across five days and expire with the rest of the package on day 7.
Only one welcome package per account; it does not stack with other campaigns unless a promotion says so.

Deposits and payouts

Deposits open at €10 on cards and SEPA Instant, and at €20 on Trustly and standard SEPA transfers, which is also the €20 the welcome package needs to qualify. Card payments run on debit only. SEPA Instant clears in half an hour at most, Trustly moves money back out from 15 minutes, and no fee is charged from this side on any of the main rails.

Skrill and Neteller work from €10 with payouts inside 24 hours, and Revolut behaves like the card rail at €10 and 1 to 24 hours. Apple Pay, Google Pay and paysafecard fund an account but cannot return money, so pair them with Trustly or a SEPA account before you request a payout.

Crypto deposits in BTC or USDT start at roughly €15 worth and settle in 15 minutes to 2 hours. Withdrawals go back to the method that funded the balance wherever the rail allows it, which is the shortest route to a same-day payout.

Deposits and payouts

Visa / Mastercard (debit)	€10	1-24 h

Take payouts back to the rail that funded the account

Fastest payout	Trustly from 15 minutes, SEPA Instant within 30 minutes

Fees	None charged from this side on the main rails

Frankenstein Slots keeps payouts on the rail that funded the balance, so a Trustly deposit returns through Trustly from 15 minutes and a SEPA Instant deposit returns to the same IBAN inside 30 minutes.

Frankenstein on a phone

NetEnt shipped Frankenstein with a Touch build, so the 5x3 grid and all 20 paylines fit a portrait screen without a separate download. Chrome, Safari and Firefox all load the game from the browser, and autoplay is supported the same way it is on desktop.

There is no app to install from a store, which also means no store update sits between you and a session. The cashier, the free spins counter and the Fire Wild round behave identically on a phone and on a laptop, and a €0.20 spin costs the same on both.

Licence, security and player controls

Who answers for this site

Curaçao is moving its old gaming-master-licence regime across to LOK licences, so the licence behind this platform is quoted exactly as the operator publishes it and never as something verified here. Answering for the site in law is the company that runs it. No national regulator authorises these pages: GRAI, MGA, Spelinspektionen, GGL, ADM, DGOJ, ANJ and KSA are named only as the bodies that govern their own domestic markets.

Payments and data

TLS encryption covers the whole session, from the cashier to the game window. Card details are tokenised rather than stored in readable form, transactions are watched for anti-fraud patterns, and player balances are held apart from operating funds as standard practice.

Staying in control

Deposit limits, loss limits, session reminders, cooling-off periods and self-exclusion are all set from inside the account and take effect immediately. GambleAware and Gambling Therapy give free, independent help in English, and Problem Gambling Ireland does the same for players in Ireland.

Legal note

An independent operating company runs Frankenstein Slots and carries all legal responsibility for it, under an international Curaçao licence. Frankenstein is a NetEnt slot developed in association with Universal Pictures; the specifications on this site describe that game. Play with money you can afford to lose and use the account limits if you need them.

What players say about the Frankenstein round

Four accounts of the same slot, all from this site's players

They talk about the free spins batches, the Fire Wild round and how fast the money came back.

Ciara DonnellyDublin · 6 days ago

★★★★★

“I came here for the spec sheet, stayed for the free spins round. The 200 spins from the welcome package landed 40 a day exactly as written, and the fourth batch hit a run where the Fire Wild covered reels 2 to 4 twice with a x4 on reel 5. Trustly sent €640 back to my bank in about twenty minutes. The 35x on deposit plus bonus is real work, but nobody hid it from me.”

Marek NowickiValletta · 23 days ago

★★★★☆

“The one thing that annoyed me is the 7 day clock on the package, because the last 40 free spins arrive on day five and that leaves very little room. Everything else has been straight: €20 in via SEPA Instant, the match credited immediately, and Frankenstein plays at 96.6% the way the page says. My best round was 610x the stake on a €1 bet during the burning mill spins. I would still start here over any review site.”

Declan MurphyCork · 31 days ago

★★★★★

“My previous casino listed Frankenstein with a rounded-up return and a max win more than twenty times the real ceiling, which I now know is nonsense. Here the numbers match what NetEnt actually shipped, and a €0.20 minimum bet lets me sit through the medium volatility stretches without burning the balance. Payouts by Skrill have landed inside a day every time.”

Anneli VirtanenGalway · 14 days ago

★★★★☆

“Dracula and Creature from the Black Lagoon are on the same shelf here, so I bounce between the three NetEnt Gothic titles. Frankenstein is the one I keep coming back to because the linked wild changes the whole 20 line grid rather than a single row. Deposits on my debit card clear instantly and the payout came back the next morning.”

Frankenstein Slots FAQ

Which Frankenstein slot is the NetEnt one?

The NetEnt Frankenstein is the 5x3 machine with 20 adjustable paylines, a 96.6% return and the Lightning Wild that spreads across reels 2 to 4. Microgaming, RubyPlay, Nucleus, Blueprint and KA Gaming all ship a differently named Frankenstein game. If the lobby tile does not say NetEnt and 20 lines, it is one of the others.

Is this the official Frankenstein Slots casino?

Yes. Frankenstein Slots is the official casino of the NetEnt Frankenstein slot and the whole site is built around that one game rather than a generic lobby. The operating company holds all legal responsibility for it.

What is the RTP of Frankenstein?

96.6%. The NetEnt-specialist return lists and Slotsjudge both publish that figure, and it is the number used everywhere on this page. Generalist aggregators sometimes round it up by a tenth of a point, which does not survive a check against the specialist sources.

What is the maximum win on Frankenstein?

1,750x the stake, which comes to €175,000 at the €100 maximum bet. The arithmetic reconciles the two published forms of the same cap. A far larger multiplier circulates on aggregator snippets and cannot be squared with the €175,000 ceiling.

How do you trigger the Burning Mill free spins?

Land 3 or more Windmill scatters anywhere on the reels and the game awards 10 free spins. During the round, 2 further scatters add 5 spins and 3 add 10. Multiplier icons on reel 5 raise line wins by x2 up to x5.

What is the difference between a Lightning Wild and a Fire Wild?

Both land on reels 2, 3 and 4 and both turn two or more adjacent positions wild. The Lightning Wild belongs to the base game and appears at random. The Fire Wild replaces it inside the free spins and is guaranteed on every spin of the round.

What are the minimum and maximum bets, and is there a demo?

Bets run from €0.20 to €100 a round, with coin values of €0.01 to €0.50 across 10 bet levels. Frankenstein is a 2015 title and demo play is offered by some sites and missing at others, so check the game window in the lobby before assuming a free round is available.

How does the welcome bonus work?

Deposit at least €20 and the match adds 100% of it up to €500, along with 200 free spins on Frankenstein credited 40 a day for five days. Wagering is 35x on deposit plus bonus and the package runs for 7 days from credit. Slot play carries the wagering.

Which payment methods work and how fast are payouts?

Visa and Mastercard debit, Trustly, SEPA Instant, standard SEPA transfer, Apple Pay, Google Pay, paysafecard, Skrill, Neteller, Revolut and crypto in BTC or USDT. Trustly pays out from 15 minutes and SEPA Instant inside 30, while cards take 1 to 24 hours. Apple Pay, Google Pay and paysafecard fund an account but cannot return money.

Is playing here legal, and who is responsible for the site?

Yes. Online casino play is open to adults across the European markets this site serves, each country under its own framework, and nothing on this page claims authorisation by GRAI, Spelinspektionen, GGL, ADM, DGOJ, ANJ or KSA. The operating company holds all legal responsibility and runs the platform on an international Curaçao licence.

Can I play Frankenstein on a phone, and how do I reach support?

Yes, the NetEnt Touch build opens in Chrome, Safari or Firefox with all 20 paylines on a portrait screen and no app to install. Support runs on email and live chat, and live chat is the quicker of the two.
