#4 – Frankenstein

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.

#6 – Scary Rich

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

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.

#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

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.
