Frightening Frankie Slot (Mini Review)
Frightening Frankie from Pragmatic Play and Reel Kingdom puts a quirky spin on the Frankenstein legend, with Frankie himself stepping into the role of the monster. Played on a 5×3 grid with 20 paylines, it runs on high volatility and a 96.53% max RTP, with stakes ranging from €0.05 to €250 per spin. An Ante Bet option doubles the stake for better odds at triggering Monster Trail Free Spins, or players can buy the feature outright.
Symbols include 10–A card ranks, buildings, torches, bolts, and moons, with premiums paying up to 4.8x the bet for 5-of-a-kind. Frankie appears as the wild on all reels, substituting for pay symbols and awarding 16x the bet for 5 wilds.
Though not the scariest slot around, Frightening Frankie offers Reel Kingdom’s familiar mix of high volatility, bonus opportunities, and nostalgic horror flair.
Frightening Frankie: Slot Overview
Editor’s note: This review is based on an early access version of the game. Details may change upon full release.
Mary Shelley’s 1818 masterpiece Frankenstein; or, The Modern Prometheus reshaped horror forever, warning of unchecked ambition, the dangers of science, and the risks of playing god. The monster at its heart has lived on in countless retellings, and now Pragmatic Play, together with Reel Kingdom, brings their own version to the reels with Frightening Frankie.
In this slot, Frankie himself takes center stage—not as the scientist, but as the monster. Grimacing from the side of the screen, he oversees the action in a design that feels part B-movie, part classic Reel Kingdom style. While it may not be the scariest slot ever made, it leans into the uncanny and quirky with a stitched-together 5×3 grid and 20 paylines. Behind it all is a highly volatile math model, offering a 96.53% max RTP across stakes of €0.05 to €250 per spin. Players can also activate the Ante Bet, doubling the stake for an increased chance of hitting the Monster Trail Free Spins, or buy their way directly into the feature.
Wins are formed left to right with symbols ranging from 10–A card ranks to thematic icons like buildings, torches, bolts, and moons. Low pays deliver up to 1.6x the bet for 5 OAK, while premium picture symbols climb to 3.2x–4.8x. Frankie himself is the wild, appearing on all reels to substitute for any pay symbol and paying 16x the stake for 5 wilds in a line.
While the game’s visuals might not terrify, Frightening Frankie mixes familiar Pragmatic/ Reel Kingdom volatility with a horror-themed twist that could appeal to fans of the monster legend and high-risk gameplay.
Features
Frightening Frankie’s lab bubbles over with three main features – Lightning Free Spins, Monster Trail Free Spins, and a Feature Buy option.
⚡ Lightning Free Spins
Triggered by landing 1 or more Lightning symbols, this round begins with 2–6 spins. Each Lightning symbol removes a low-paying symbol (up to 5 total) and awards an extra 2–6 spins. Once all 5 lows are gone, no further Lightning symbols appear. If 3 or more scatters land during this bonus, it upgrades to Monster Trail Free Spins, with any unused spins carried over.
👣 Monster Trail Free Spins
Landing 3, 4, or 5 scatters awards 10, 15, or 20 free spins. If only 2 scatters appear, a random lightning strike may add a third to trigger the feature. The round starts with a 2x global multiplier, which grows as modifiers kick in. Lightning symbols again remove up to 5 low-paying symbols from the reels, while Test Tube symbols are collected in a meter. Every 7 Test Tubes grant +10 spins and add a random multiplier of x1–x10 to the round’s total multiplier.
💀 Feature Buy
Players can jump straight into Monster Trail Free Spins for 100x the bet, starting with 3–5 scatters.
Frightening Frankie: Slot Verdict
Mary Shelley’s classic has spawned endless adaptations, but Reel Kingdom’s Frightening Frankie lands somewhere in the middle of the pack. The base game doesn’t offer much to get excited about, leaving the heavy lifting to the two bonus rounds. Both lean on the shared mechanic of low-symbol removal, which can certainly improve the math when enough Lightning symbols hit.
The Lightning Free Spins round feels like a warm-up more than a standalone feature, trimming down the reels before the real show begins in Monster Trail Free Spins. With its multipliers and Test Tube collections, the latter has moments of promise, though the experience depends heavily on symbol removals lining up in your favor.
In terms of win potential, Frankie isn’t the beast you might expect — maxing out at 2,800x the bet, which is modest by modern standards. That places it in Big Bass Bonanza territory but without the charm of the fish-themed collection mechanic.
Overall, Frightening Frankie is more stitched-together experiment than electrifying masterpiece. The B-movie style has appeal, and some players may enjoy its quirky atmosphere, but its gameplay lacks the spark needed to truly bring this monster to life.
