This green-skinned giant, adorned with bolts in his neck, made his debut in Mary Shelley’s 1818 novel Frankenstein, a pioneering work often regarded as the first science fiction novel. Shelley created this masterpiece when she was just 18 years old during a summer spent with other renowned writers like Percy Bysshe Shelley and Lord Byron on the shores of Lake Geneva. The novel delves into themes of science, ambition, and the essence of humanity. In this game, Reel Kingdom reimagines the monster as a fun, prize-giving slot host.

Frightening Frankie is a video slot featuring 5 reels, 3 rows, and 20 paylines. Players can place bets ranging from a minimum of 0.05 to a maximum of 250, which can increase to 500 by utilizing the Ante Bet feature. The slot offers a maximum win of 2,800x the bet, a hit frequency of 24.51%, and a Free Spins hit frequency of 1 in 57 spins. The RTP is set at a default of 96.53%, with variations available at 95.53% and 94.53%. The game’s volatility is categorized as very high, appealing to players who favor larger risks and rewards.
Visually, Frightening Frankie embraces its horror theme with a dark color palette of blacks, blues, and purples. The reels are set against a blue backdrop with Frankenstein’s Monster to the right, displaying his green visage, a green coat, and the two screws protruding from his neck. Black birds circle in the misty background, while a large moon illuminates the upper left corner. Wins are obtained by landing matching symbols across paylines, starting from the first reel on the left. The game operates smoothly on mobile phones, tablets, and desktop computers.
The lower-paying symbols include 10, J, Q, K, and A, which result in a payout of 1.6x the bet for a win of 5 symbols. The higher-paying symbols consist of the haunted house, torch, screws, and earth, yielding between 3.2x and 4.8x the bet for a 5-of-a-kind win. The Wild Symbol is represented by Frankenstein’s Monster, substituting all regular symbols to complete wins, excluding the Scatter, Lightning, and Test Tube symbols.
What is the max win in the slot Frightening Frankie?
The maximum win is 2,800x the bet.
What features are available in the slot Frightening Frankie?
The available features include Wild Symbol, Lightning Free Spins, Monster Trail Free Spins, Ante Bet, and Feature Buy.
The Wild Symbol substitutes all regular-paying symbols to form wins on paylines, but does not substitute the special symbols: Scatter, Lightning, and Test Tube.
When one or more Lightning symbols land, the Lightning Free Spins feature activates. At the round’s beginning, one lowest-paying symbol is removed from the reel strips for each Lightning symbol that triggered the round. The bonus starts with a random number of free spins, ranging from 2 to 6. Every time one or more Lightning symbols appear during the feature, it retriggers with an additional 2 to 6 free spins, and more of the lowest-paying symbols are removed, up to a maximum of 5 symbols. After the fifth symbol is removed, Lightning symbols can no longer appear for the remainder of the round. Landing 3 or more Scatter symbols during this feature triggers Monster Trail Free Spins, and any remaining free spins carry over.
Triggering 3, 4, or 5 Scatter symbols activates the Monster Trail Free Spins feature, awarding 10, 15, or 20 free spins, respectively. In the base game, if only 2 Scatter symbols appear, a lightning animation may add a third Scatter to activate the feature. This round commences with a 2x multiplier applied to all wins. The Test Tube symbol only appears during Monster Trail Free Spins. Lightning symbols during this round remove the lowest-paying symbols permanently, with a maximum of 5 symbols being removed. Collecting Test Tube symbols fills a meter, and once 7 are collected, the round retriggers, providing 10 additional free spins and a random multiplier of x1, x2, x5, or x10 added to the current multiplier.
Players can double their bet to enhance their odds of triggering bonus games, while the paytable remains unchanged.
Players have the option to instantly trigger the Monster Trail Free Spins round from the base game by purchasing it for 100x their current total bet. When buying the feature, 3, 4, or 5 Scatter symbols will randomly appear on the triggering spin.
Playing Frightening Frankie feels like stepping into a chilling Halloween gathering organized by Frankenstein’s Monster himself, where instead of candy, he rewards players with free spins and multipliers. The blend of two distinct free spin rounds, symbol removals, and random multiplier boosts makes the gameplay dynamic and thrilling. The Test Tube collection mechanic in the Monster Trail Free Spins adds a “progress bar” element to the bonus round, enhancing the excitement as players hope for more Lightning symbols and Test Tubes to accumulate significant wins.
It is important to note the game’s high volatility, which may result in extended periods without substantial wins; however, when wins do occur, they can be quite rewarding. During the demo, there were several occasions where symbol removals aligned, and the multipliers transformed small wins into unexpectedly large payouts. Despite the dark theme, the artwork is more whimsical than terrifying, making it accessible even for those who typically avoid horror themes.
However, the maximum win of 2,800x the bet is relatively low for a game with such high volatility. If you are interested in exploring other horror-themed games, consider trying out titles like Nightmares VS Gigablox, where the potential win reaches up to 7,353x, or Horror Hotel, which offers a maximum win capped at 20,000x the bet.
Overall, Frightening Frankie from Reel Kingdom is an engaging and enjoyable slot, featuring classic horror visuals and a captivating atmosphere.
