Star Clusters 2: Slot Overview
When Star Clusters first launched in 2020, Big Time Gaming introduced its Megaclusters mechanic—a system that broke winning symbols into smaller ones for chain reactions. While Megaclusters never dominated the industry the way Megaways did, it carved out a niche and has returned occasionally over the years. Now comes Star Clusters 2, a sequel that preserves the core grid-based gameplay while refining supplementary features like wild multipliers and free spins to create a more streamlined experience.
This time, the theme shifts into a sleek, digital dimension. The neon, Tron-like grid glows against an infinite backdrop, pulsing to a celestial electronic soundtrack. It feels like a retro-futuristic afterlife for video game avatars, where clusters of gems form and dissolve in an endless loop. The base game starts with a 4×4 grid, expanding to an 8×8 layout during free spins. Wins form when 5 or more identical symbols connect horizontally or vertically, triggering cascades and other effects. Stakes range from €0.20 to €20 per spin, with three RTP settings available—the highest at 96.63%—and a highly volatile math model underpinning the action.
The paytable is made up of seven gem symbols, awarding between 0.1x and 0.8x the stake for 5-of-a-kind clusters, climbing up to 88x for 25+ symbol clusters (or fewer, for premium gems). Wilds substitute for adjacent symbols, while Gold Wilds carry random multipliers from x2 to x100. When multiple wilds land in a winning cluster, their multipliers combine, boosting payouts into potentially explosive territory.
