Steampunk Big City presents a steampunk aesthetic anchored by hat, weapons, blue and orange tones, clockwork elements, airships, butterflies, a smoking pipe, and steel. The presentation centers on the RTP range and Free Spins, with Gamble highlighted as a feature within the visual frame. The overall composition emphasizes brass textures, gear-driven motifs, and a cityscape that blends industrial imagery with whimsical details, while maintaining a restrained, observational tone in its thematic narration.

Additionally, the feature set includes Free Spins, Scatter symbols, Wilds, and Stack interactions, with a Gamble (Double) option described as a risk feature. The implementation favors clear symbol behavior and modular interaction, avoiding overstatement about outcomes. Visual cues accompany the mechanics, enabling players to track bonus arrivals and symbol growth without implying guaranteed results.
