#1 – Frankenslots Monster

Frankenslot’s Monster
  • Software: Betsoft
  • Release Date: 2016
  • Reels: 5×3
  • Paylines: 20
  • Min/Max Bet: $0.20/$36
  • RTP: 96.83%

Frankenslots Monster is a Betsoft creation that features smooth animations on a 5×3 gameboard. Hitting three scatter symbols awards you eight free spins, while electric shocks turn anywhere from 1–3 symbols wild for even bigger wins.

And if you hit the bonus round you can adjust a series of electric handles to shock the monster, winning up to 25x your bet in the process. This is the best part of the game, as it puts you in the shoes of a mad scientist harnessing electricity to raise your creation from the dead. I’m not exactly sure what the reasoning behind the feature is, but it’s sure fun to adjust the knobs and flip the switch!

#2 – Freaky Frankenstein

Freaky Frankenstein

  • Release Date: 2017
  • Reels: 5×3
  • Paylines: 20

Freaky Frankenstein electrifies players with a 5×3 gameboard and 20 paylines to win big. The Nucleus Gaming title features a fun, cartoonish 3D animated art-style with scatter wins, bonus rounds, and a unique Double Up option that allows you to flip a coin to double your winnings.

The game features a maximum multiplier of 2,500x your bet, which at a maximum bet of $7 would bring you over $17,000! That might not be enough for you to buy a gothic castle of your own, but it should be enough to allow you to rent one for the weekend!

Our Freaky Frankenstein review digs deeper into the game, and when you’re ready you can head to Super Slots to get in on the action.

#3 – Monster Manor

  • Software: Woohoo Games
  • Release Date: 2021
  • Reels: 5×3
  • Paylines: 50 fixed
  • Min/Max Bet: $0.50/$100
  • RTP: 97.30%

Monster Manor is a ghoulish Frankenstein slot game for online players. The RTP is a juicy 97.30%, and you play 50 fixed paylines on each spin. Meanwhile, a creepie soundtrack plays out as you spin the reels. The colorful animated monsters and eerie house reminds me of spooky movies like The Addam’s Family or Hotel Transylvania. I could play this one all day.

Like the best online slots, you play Monster Manor on a standard 5×3 set-up. Black cats are single wilds, while expanding wilds can cover an entire reel for even bigger wins.

Monster Manor also features a generous free spins bonus when you land 3–5 scatters. You trigger 10 free spins with a 3x multiplier on every win. Play it now at Wild Casino and see for yourself why Wild Casino is so highly rated for Frankenstein slots and other games.

#4 – Frankenstein

frankenstein ka gaming
  • Software: KA Gaming
  • Release Date: 2020
  • Reels: 5×3
  • Paylines: 50 fixed
  • Min/Max Bet: $0.50/$250
  • RTP: N/A

KA Gaming’s Frankenstein slot is the simplest game on our list in terms of overall gameplay. It’s also the only Frankenstein-themed slot on the list to contain mega reels.

It features a 5×3 set-up with 50 paylines, and you can win eight free spins by landing scatter tiles. Not only that, but a mega reel activates during the free spins bonus. The center reels merge to become one giant reel, and the mega reel is guaranteed to land on every spin during the bonus.

My favorite part about KA Gaming’s Frankenstein is that it hits frequent wins, even if the wins aren’t the biggest in the world. I’d rather have a game hit often for less than barely hit at all, as it keeps games more exciting for me, personally. MyBookie is one of my go-to casinos for the Frankenstein slot machine.

#5 – Mega Monster

Mega Monster RTG
  • Software: RealTime Gaming
  • Release Date: 2024
  • Reels: 5×3
  • Paylines: 20–60
  • Min/Max Bet: $0.40/$100
  • RTP: 96%

Mega Monster is one of the newer Frankenstein slots on our list. It was released in 2024 by RTG and features a range of bonuses, including wilds and free spins. It’s cool how a lot of the symbols look like Halloween candy too, makes the whole thing feel really in the spirit of the season. Plus the cartoonish vampires, robots, and werewolves are really fun.

A random Sliding Reels feature triggers during the base game or the free spins feature. Franky the monster often transforms into a wild symbol too, adding a fun variable to every spin. In addition, reels 2–5 slide to the left to create potential new winning combinations.

OnlineCasinoGames is the best site to play Mega Monster.

#6 – Scary Rich

Scary Rich Rival Gaming
  • Software: Rival Gaming
  • Release Date: 2007
  • Reels: 5×3
  • Paylines: 20
  • Min/Max Bet: $0.20/$100
  • RTP: 96.70%

Rival Gaming’s Scary Rich is the first in a series of Frankenstein slots featuring Frankenstein-like monsters, witches, vampires, and more. Released in 2007, Scary Rich shows its age a little, but the 20-payline gameplay still delivers. The flashing skulls that appear behind the spinning reels is a cool touch. I also appreciate the hand-drawn symbols that make it feel like something you would have drawn in your notebook in high school.

Frankenstein’s monster acts as a scatter symbol. You can trigger 10 free spins by hitting 3+ Frankenstein scatters in any position. Plus, the free spins feature expanding wilds with a progressive multiplier for each successive win.

Ignition Casino is my favorite Frankenstein slot machine app for ghoulish slots like Scary Rich. You can activate a welcome bonus worth up to $5,555 when you sign up!

#7 – Scary Rich 2

Scary Rich 2 Rival Gaming
  • Software: Rival Gaming
  • Release Date: 2008
  • Reels: 5×3
  • Paylines: 20
  • Min/Max Bet: $0.20/$100
  • RTP: 95.28%

Scary Rich 2 was released in 2008, a year after Rival Gaming launched its range of spooky themed slots which included the original Scary Rich game. The second entry in the series features 20 paylines and a much bigger multiplier of up to 13x your wager (versus 4x in the original).

The art style still feels hand drawn like in the first Scary Rich, but takes on a darker, more sinister tone. And with symbols like a chef’s knife and scary clowns, it almost feels more like a slasher movie than a gothic horror movie.

The game features expanding wild symbols in the form of coffins, offering a spooky way to increase your winnings. And with bets as high as $20 per spin, you can potentially win a lot of money.

Want to play Scary Rich 2? Bovada is an awesome choice if you want to play real money slots online.

#8 – Scary Rich 3

  • Software: Rival Gaming
  • Release Date: 2013
  • Reels: 5×3
  • Paylines: 50
  • Min/Max Bet: $0.50/$125
  • RTP: 94.21%

Scary Rich 3 is the third entry to Rival Gaming’s spooky slot series. The game was released in October of 2013; five years after the second entry. It features a 3D animated style, rather than the hand-drawn 2D look of the first two. Its style returns to the more cartoonish theme of the first Scary Rich, though the blood splatters while the reels spin make it feel more sinister than the first game.

The game features 50 paylines — more than double the 20 paylines found in the first two games. Scary Rich 3 has an RTP of 94.21%, however, which is the lowest of the trilogy.You’ll find regular symbols like Frankenstein’s monster, skulls, and dungeon keys. There’s also werewolf wild symbols that upgrade to expanding wilds during free spin rounds.

Café Casino is our most recommended online casino to play Scary Riches 3. You can get a welcome bonus worth up to $2,500 if you sign up today.

#9 – Frankenstein’s Rebirth

Frankenstein's Rebirth
  • Software: Spinomenal
  • Release Date: 2025
  • Reels: 5×3
  • Paylines: 5
  • Min/Max Bet: $0.05/$50
  • RTP: N/A%

You can win up to 5,000x your wager in Frankenstein’s Rebirth, a slick three-reel slot released in 2025. The game combines classic three-reel thrills with bonus features like chase’n’win scatter symbols that can trigger multiple free spin rounds. I’m a big fan of three-reel slots, and it’s cool to see a spooky Frankenstein themed title within the format. I also like that there’s an ethereal Bride of Frankenstein symbol as well.

The game features five paylines, and a jackpot of 120x your wager when you land five Frankenstein’s monster symbols.

#10 – Spooky Wins

  • Software: RealTime Gaming
  • Release Date: 2023
  • Reels: 5×3
  • Paylines: 30
  • Min/Max Bet: $0.30/$150
  • RTP: 96%

Spooky Wins is a light-hearted Halloween themed slot with a cartoonish art style. The game features a cute Frankenstein type little boy symbol, as well as zombies, witches, and werewolves. All of the symbols sparkle too, which gives it a fun light-hearted feel that I appreciate. I also like that the Frankenstein boy has blue hair, which pairs nicely with his bright green skin.

Bets start at just $0.30, and go up to $30 per spin. The 5×3, 30 payline slot has wild symbols and scatter tiles that trigger bonuses like a bonus wheel, wild reels, and expanding reels that increase the gameboard to 5×6.

You can also win up to 20 free games. We recommend Sloto’Cash as the best place to play Spooky Wins.
