Street Mahjong by Espresso Games blends urban visuals with Mahjong iconography, using a black and blue color palette. The presentation centers on a thematic fusion rather than conventional cues, and the volatility profile is high. Tile-inspired motifs anchor the composition, supporting a consistent, game-wide aesthetic.
Additionally, cascading reels operate with avalanche-style sequences that remove winning symbols and allow new symbols to drop in, creating successive chances on the same spin. Scatter symbols, Wilds, and Bonus symbols trigger a range of features, including Bonus Game, Free Spins, and Buy Feature. Respins extend round duration and can accompany Multipliers to increase win potential. The interaction with Cluster Pays and the Symbols collection (Energy) framework introduces alternate payoff paths and pacing. The Energy collection mechanic gathers symbol energy across cascades, potentially contributing to future outcomes within the same session.
In practice, the game presents a layered payout structure where secondary features interact with core cascades. RTP is 96%, layout is 7-6, minimum bet is USD 0.1, maximum bet is USD 150, and the top win is 15x.
