#1 – Monster Manor
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 spooky soundtrack plays out as you spin the reels.
Like the best online slots, you play Monster Manor on a standard 5×3 set-up. Black cats are single wilds, but expanding wilds can cover an entire reel.
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. Try it now at Wild Casino and claim a sign-up bonus.
#2 – Freaky Frankenstein
This Frankenstein slot machine isn’t dissimilar to the previous one I reviewed. Like the Ruby Play-powered slot, the one by Nucleus Gaming also features characters from the 1930s classic horror movies.
The only difference is that the ones you see in the Freaky Frankenstein slot are a bit goofier. Actually, the entire game is more colorful than you’d expect from a slot with Frankenstein as the main character.
The most you can win playing Freaky Frankenstein is 2,500x your total bet. At BetUS, you can bet up to $7 per line, and considering that there are 20 paylines in this game, your max. bet is $140. This means that if you hit the main prize on max. bet, you will get $350,000 in your account.
You can read more about BetUS with our gambling site review, or head straight there to begin playing this Frankenstein slot machine.
#3 – Frankenslot’s Monster
Frankenslot’s Monster by Betsoft is another 5-reel 3-row game with 20 paylines and a 93.83% RTP. Its graphics are also very similar to the ones from the Nucleus-powered slot, and the same goes for the symbols.
If Frankenslot’s Monster is your pick, you can play it for real money at TrustDice. This is perhaps the best crypto casino online and offers over 2,500 casino games.

#4 – Frankenstein
KA Gaming’s Frankenstein slot is probably 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.
You play Frankenstein on a standard 5×3 set-up with 50 paylines in operation. You win 8 free spins by landing 9 scatters on the middle 3 reels.
Plus, a mega reel is activated during the free spins bonus. The center 3 reels merge to become one giant reel. In addition, the mega reel is guaranteed to land fully on every spin.
We recommend reading our review of Slots Paradise to see why it’s the go-to casino for Frankenstein slots.
In fact, Slots Paradise boasts a good range of Halloween-themed slots too, including Halloween Treasures. Plus, you can claim free spins as part of your welcome bonus.
#5 – Mega Monster
Mega Monster is one of the newer Frankenstein slots on our list. It was released in 2024 by RTG and features free spins and wild symbols.
A random Sliding Reels feature triggers during the base game or free spins. Franky the monster transforms into a wild symbol when he appears on the screen. In addition, reels 2–5 slide to the left to create potential new winning combinations.
Mega Monster also features expanded reels, extra wilds, and 10 free spins. Try it for free now at OnlineCasinoGames and trigger a monstrous 400% deposit match deal.
