Jelly Boom by Evoplay uses a 4-4 grid with 40 paylines, and the presentation leans toward dark blue visuals, monster motifs, and orange accents, with green and pink tones in the overall palette.

Mechanically, the game features Avalanche and Cascading reels, Scatter symbols that can trigger features, Wilds that substitute to complete winning combinations, and a Multiplier that can amplify payouts. Additionally, Free Spins are part of the feature set. The bet is defined within a range from USD 0.1 to USD 500 per spin. RTP is 96%, and the top win is x95. Pacing is influenced by volatility.

That said, in practice Jelly Boom combines the feature set with a bold color palette and a compact grid presentation, delivering a neutral, high-variance slot experience.
