Woop Woop Gameplay

Explore the vibrant world of Woop Woop, a thrilling online slot from Merkur Gaming released in 2019. This 5-reel, 3-row fruit-themed game offers players a dynamic experience with its medium volatility and a return-to-player (RTP) rate of 96.15%. Players can adjust their stakes from as low as $0.01 up to $20 per spin, catering to both newcomers and seasoned slot enthusiasts.

Woop Woop features 10 selectable paylines, providing ample opportunities to win up to 1000 times your stake. The gameplay is enhanced by unique stack upgrade features, where matching three identical symbols on a single reel triggers upgrades of other symbols across the reels. For instance, landing three ‘7’ symbols on a reel will upgrade all ‘A’ symbols to ‘7s’, increasing your winning potential.

The game also includes a wild symbol that substitutes for all other symbols, further boosting your chances of scoring high-value combinations. Wins are calculated from left to right, right to left, and across the middle, ensuring that every spin could be a big win.

Engage with Woop Woop’s gamble feature, where you can choose to play the card gamble by guessing the next card’s colour, or climb the risk ladder to potentially increase your winnings. This feature adds an exciting layer of strategy to the game.

Our Review


Woop Woop by Merkur Gaming scores a solid 3.7 out of 5. The stack upgrade feature, which upgrades symbols across the reels, adds a layer of excitement and strategy. The selectable paylines and gamble feature offer customisation and risk-taking opportunities. However, the maximum bet of $20 may deter high rollers, and the absence of a jackpot feature limits its long-term appeal. The medium volatility ensures balanced wins, while the vibrant fruit theme keeps gameplay lively. To further enhance this slot, an increased maximum bet and additional bonus features could improve player engagement.
