Tom Horn offers slot fans an adult-themed experience with its Red Lights slot. Inspired by the famous Red Light District in Amsterdam, the Netherlands, this video slot combines a provocative theme with several bonus features. The game features five reels and three rows, with nine fixed paylines that award payouts in the base game.
Female characters serve as the game’s special symbols, triggering generous bonus features. Players can activate free spins with a 2x or 4x win multiplier. During free spins, winnings are paid both ways, which means there are 18 paylines in the bonus game. Red Lights has a respectable RTP of 96% and medium volatility.
Red Lights Theme, Graphics, and Sounds
During the day, Amsterdam’s Red Light District features typical Dutch architecture in one of the city’s oldest areas. The district’s beautiful buildings appear behind the slot’s grid, offering a glimpse of how the area looks at night.
Because the Red Light District is famous for its bright red neon lights, the game’s symbols evoke the fluorescent glow that covers the area after dark. The background music captures the relaxed atmosphere of a gaming hall, punctuated by mischievous female laughter. Blonde and brunette characters also feature prominently throughout the game.

Red Lights Symbols and Payouts
Regular symbols in Red Lights award a payout when at least three matching symbols appear on one of the nine paylines. In the base game, winnings are paid only from left to right, which means the winning line must start on the far-left reel. During free spins, however, lines pay both ways, creating 18 paylines and allowing some combinations to pay when they start on the far-right reel.
The low-paying symbols in Red Lights are the traditional playing-card values ranging from 9 to A. Illuminated in neon red, these icons are divided into three groups. The 9 and 10 symbols pay 5x, 20x, and 50x the line bet when three, four, or five matching symbols land on a payline. The next group, J, Q, and K, pays 10x, 20x, and 75x the line bet for combinations of three, four, or five identical symbols. Finally, the A is the most lucrative symbol in this category, awarding 10x, 50x, or 100x the line bet when it appears three, four, or five times, respectively.
The high-paying symbols include yellow, blue, and red diamonds. These gems award generous payouts for three-of-a-kind and four-of-a-kind combinations. Five matching symbols pay 200x, 300x, and 400x the line bet, respectively.
The game also features two female silhouettes that act as Wilds, substituting for all other symbols. These icons appear only on the first and last reels and also serve as Scatters, triggering the Free Spins feature.

Red Lights Bonus Mechanics
Red Lights includes several bonus features. As mentioned above, the Wild girls can replace other symbols, helping players complete winning lines. The Wilds appear only on the first and last reels and expand to cover the entire reel.
When one Wild girl lands on either the first or last reel, players receive five free spins with a 2x win multiplier. The expanded Wild remains in place for the entire feature. If the second Wild appears on the opposite reel during the Free Spins feature, the free spin count resets to five and the multiplier increases to 4x. Should both Wild girls land simultaneously on the first and last reels, the bonus feature begins with five free spins and a 4x multiplier.
During the base game, the Mystery Win feature may be triggered at random. It reveals three X symbols in the center of the reels and awards a random prize. This feature can award up to 50x your total bet.
Like many other video slots, Red Lights offers a Gamble Feature every time you land a win. The game adds a provocative twist by turning it into the Strip Gamble Feature. The screen displays a woman’s silhouette, with a blonde in red lingerie on the left and a brunette in black lingerie on the right. Your goal is to guess whether the silhouette belongs to the blonde or the brunette.
Each correct guess removes a piece of clothing from the chosen girl and doubles your win. If you do not want to risk your entire base-game win, you can wager only half of it. After every correct guess, you may either collect the doubled payout or continue gambling. Each time you identify the girl correctly, she removes another garment. After three correct identifications of the same girl, she transforms into a fully naked Joker. Once a girl becomes a Joker, you are guaranteed not to lose the next round of the Gamble game.
Even if you guess incorrectly while the naked Joker is on the screen, you will not lose your stake. Be careful, though, because a wrong guess during a normal round of the Gamble Feature will cost you the entire amount you gambled.
