Where to Play Frightening Frankie
Frightening Frankie RTP and Wagering
Frightening Frankie features a standard 5x3 reel layout with 20 fixed paylines. You can build winning combinations with three, four, or five identical symbols on any payline. Depending on your bankroll, you can bet from £0.05 to £500 on each spin.
With an above-average theoretical RTP of 96.53%, the Frightening Frankie slot has the potential for a decent return over time. However, the maximum payout on offer is modest at just 2,800x your bet, and it seems especially low for a highly volatile slot. Other spooky slot games on the market (such as Immortal Romance and Curse of the Werewolf Megaways) offer much bigger cash prizes.
Frightening Frankie Symbols and Audio & Video Design
Frightening Frankie’s visuals are an absolute treat for fans of the classic Frankenstein movies starring Boris Karloff. The creature himself is always visible to the right of the reels while you play, with his iconic green skin, neck bolts, and forehead stitches.
Alongside Frankie himself, you’ll also see a glowing white moon with bats flying in front of it, twinkling stars, and a dark, vast forest. It’s all brilliantly gothic and atmospheric - perfect for the character. And let’s not forget the music, which is brilliantly fun and eerie.
How about Frightening Frankie’s symbols? Frankie himself doubles as the Wild and the top-paying symbol, though that’s not saying much. If you land 5 of the Frankie symbols, you’ll win just 16x your bet.
Other symbols include a full moon, Victor Frankenstein's gothic castle, and electrified bolts. Bonus symbols may land on any spin, and I’ll explain how these work later in this Frightening Frankie review.

Frightening Frankie Mobile Features
The Frightening Frankie slot looks terrific on mobile devices. The visuals and sound are just as compelling as in the desktop version, and the responsive design means the layout adjusts to fit any screen. You can switch between portrait and landscape views seamlessly, too.
Frightening Frankie Bonus Features
Frightening Frankie boasts two bonus features: Lightning Free Spins and Monster Trail Free Spins. They add depth to the game and bring you more chances to win.
Lightning Free Spins
Land at least one Lightning symbol to trigger the Lightning Free Spins round. When it starts, one low-paying symbol is taken from the reels for each Lightning symbol that hits. This continues throughout the feature, and up to five symbols may be removed.
You’ll receive between two and six free spins at the start of the round, but you’ll retrigger the feature whenever a Lightning symbol strikes.
If you land at least three Scatters on a free spin, you’ll unlock the Monster Trail Free Spins feature. The remaining free spins are added to the start of the Monster Trail Free Spins round, and any low-paying symbols already removed will stay out of the game for the duration of the feature.
Monster Trail Free Spins
Match 3, 4, or 5 Scatter symbols to win 10, 15, or 20 Monster Trail Free Spins, respectively. If you land just two Scatters during a base game spin, lightning may strike at random and add a third Scatter to trigger this feature instantly.
This feature transports you to a colourful lab, with a spider dangling beside the reels, a potion bubbling away on a worktop, and even eyes floating in a container. The music takes a wilder turn, upping the tempo to create a more frantic and ghoulish atmosphere.
An x2 multiplier applies to all payouts awarded in the Monster Trail Free Spins round, and Lightning symbols will remove low-paying symbols (as in the Lightning Free Spins feature).
Each time you land a Test Tube symbol during this feature, it will be added to a meter. Collect seven Test Tube symbols to retrigger the feature and win 10 additional free spins with a random multiplier of x1, x2, x5, or x10.
Buy Free Spins
You may trigger the Monster Trail Free Spins instantly in the base game, but it costs 100x your bet.
Frightening Frankie Final Thoughts
Frightening Frankie is an entertaining and well-designed slot, and it’s sure to appeal to fans of the Frankenstein story (especially the classic black-and-white Universal movies). The two free spins features offer additional chances to win, with multipliers for potentially bigger payouts.
However, the symbol values are tiny, and the maximum payout pales in comparison to the top prizes available in so many other slots.
With plenty of B-movie charm and eye-catching graphics, Frightening Frankie still has a lot to like. But anyone who prefers to play for bigger wins will be left wanting.
