Double Stacks slot review

Double Stacks by Netent Slot Review

NetEnt brings a touch of brilliance to the classic online and mobile slot game, Double Stacks. With vibrant colors and engaging gameplay, it appeals to fans of traditional fruit machines while incorporating an innovative ‘double symbols’ feature. Players can enjoy the familiar theme with an added twist of excitement.


The theme of Double Stacks pays homage to the nostalgic fruit machines of the past, but NetEnt infuses it with their signature crisp and contemporary flair. Balancing familiarity with innovation, the game features well-known symbols and straightforward gameplay, all while surprising players with excellent additions like the Double Stack symbols and a relaxing atmosphere.

Graphics and Sound

The graphics in Double Stacks are sharp, with a neon glow that highlights each symbol on the reels, enhancing the visual experience. The clean and uncluttered interface adds to the game’s aesthetic appeal, making it user-friendly. Players will find a mix of classic slot symbols, including diamonds, sevens, bars, bells, and fruits—familiar to veteran players and comforting for newcomers.

The symbols, ranked from lowest to highest paying, are Watermelon, Lemon, Plum, and Cherry (all with the same value), followed by Bell, Bar, 7, and Diamond.

The Star serves as the Wild symbol, substituting for all other symbols except the Scatter.

Circle Scatter symbols trigger the Free Spins feature.

To accompany the visuals, a funky, laid-back soundtrack complements the action on the reels. Well-crafted sound effects heighten the excitement of winning combinations and feature triggers, maintaining an energetic gaming atmosphere that keeps players engaged.


Double Stacks doesn’t hold back when it comes to features. One standout aspect is the Double Stacks feature, where symbols on the reels can appear as doubles, counting as two symbols for calculating wins. This can lead to more substantial payouts, especially when higher-value symbols land in double stacks. Additionally, the game offers Free Spins triggered by landing three or more Scatter symbols. Players can start with as few as 5x Free Spins, but this can increase to 30 Free Spins based on the number of Scatters. During Free Spins, Wild symbols can also appear in stacks, further enhancing the potential for significant wins. Plus, Free Spins can be retriggered by landing additional Scatters during the Free Spins round.
