Editor's notes

One of Endorphina's most recognisable titles — introduced the "fiery female joker" character later reused across the provider's joker series. Classic fruit aesthetic on a modern 5×4, 40 fixed paylines. Stacked symbols + stacked Wilds: the Joker Wild substitutes all paying symbols and lands stacked during Free Spins, realistically filling entire reels. Free Spins: 3/4/5 Star Scatters → 10/20/30 spins. Classic Risk Game (Endorphina signature): card-vs-dealer double-or-nothing up to 10 consecutive wins — the Joker card beats all and only the player can draw Jokers, so the gamble edge favours the player slightly (unusual, worth noting). ⚠ Bonus Pop RTP penalty — key consumer finding: the buy feature (10/20/30 free rounds for 55x/109x/164x stake) lowers RTP from 96.07% to 95.05% — the opposite of most buy features which typically raise or match base RTP. Documented in the official paytable. This is a genuine consumer-relevant transparency note: buying the bonus in Joker Stoker is mathematically worse than triggering it naturally. Max win 2,000x (€200,000 cap at €100 max bet). Bet range from €0.40. Sister titles in Endorphina's joker series: Joker Ra, Hell Hot series, Joker Stoker Dice (dice reskin, same dual-release pattern as Crown Coins Dice).
