RTP Wild Joker Stacks is a video slot from Yggdrasil Gaming with a medium-high volatility profile and an RTP of 95.60%. The game uses the Infinity Reels mechanic, while stacked wilds are designed to cluster wins across the reels. The review and demo version are available for players who want to play for free and study the layout before playing for real money.
Two betting options shape the base game. Wild Joker Bets increase the size of the wild multiplier, while Joker Row Bets expand the number of rows on the reel set. This gives players a choice between different reel layouts and multiplier levels, with the game presented in a 16:9 format and mobile support included.
The slot was released on 9 August 2021 and lists a maximum win of €230,560. Wild symbols are central to the mechanics, with stacked wilds influencing how wins build across spins. The game is also localised in multiple languages, including English, German, Spanish, French, Italian, and Portuguese.
