Step into the gritty underworld of King of the Streets, a high-stakes cluster-pays slot from Slotmill where Don Corlion—a cigar-smoking, gun-toting lion gangster—rules the reels. Set against a roaring 1920s New York backdrop, this 6×6 slot fuses streetwise swagger with feature-packed mechanics, including Avalanche wins, Coin Clusters, Multiplier Safes, and escalating Free Spins modes. With high volatility, a 96.04% RTP, and a 15,000x max win, it’s a brutal climb to the top—but one that rewards bold players.
King of the Streets does not have the usual paylines but requires matching symbols in a cluster (a.k.a. cluster pays) instead. The game has more features than most other slots, including Bonus Bet, Burst Mode, Buy Feature, Cascading Reels, Cluster Pays, Extra Spins, Increasing Multiplier, Random Multiplier, Super Free Spins, Wilds, and more. King of the Streets also has a free spins bonus round and this is where you have the chance to win some serious cash.
The standard RTP (Return to Player) for King of the Streets slot is 96.04% (Could be lower on some sites). This payback is good and considered to be about average for an online slot. Theoretically, this means that for every €100 put into the game, the expected payout would be €96.04. However, the RTP is calculated on millions of spins, which means that the output for each spin is always random.
The highest possible payout for this slot is 15000x your total bet which is very high and gives you the chance to win really big wins. The maximum possible win is also calculated over a huge amount of spins, often one billion spins.
King of the Streets is a volatile slot, and Slotmill rates the volatility High (4/5). Volatility, in the context of slot games, refers to how often and how much a slot game pays out. King of the Streets is designed to appeal to those who enjoy the adrenaline rush of substantial winnings that low volatility slots can't deliver, and are willing to accept the inherent risks of less frequent payouts.
King of the Streets delivers a hard-hitting slot experience with its gangster-lion theme, cinematic design, and explosive bonus features. The Avalanche mechanic and Coin Cluster wins offer fast-paced excitement, while Multiplier Safes and non-resetting multipliers in Free Spins crank up the tension and payout potential. The addition of Super Free Spins and feature buys gives players flexibility and high-roller appeal.
That said, its high volatility means win streaks can be rare, and its stylized gangster theme may not resonate with those who prefer brighter or more conventional slot worlds. Still, for those who thrive on edgy vibes and creative gameplay, King of the Streets is a bold contender ready to take the crown.
