Merge Up is BGaming’s take on progressive cluster gameplay, built around a 6×6 grid where winning symbols don’t just disappear—they evolve. Every time a cluster of four or more matching symbols lands, part of that group upgrades into a higher-tier gem while the rest clears away, making space for fresh drops. This loop of merge → cascade → merge gives even base-game spins a sense of momentum and compounding potential.
The bonus round is where the slot’s identity really shines. Land 4, 5, or 6 Scatters to receive 15, 18, or 20 Free Spins. Here, any winning cluster marks its cells on the grid. If a marked position participates in another win during the same bonus, it gains a sticky multiplier (starting at ×2) that escalates each time it’s involved in a subsequent hit. When multiple boosted cells join the same cluster, their multipliers combine, creating the high-end payouts that define Merge Up’s reputation. Retriggers extend the round, and some operators also enable Bonus Buy for instant access. If you prefer natural entries, the Chance ×2 option slightly raises your trigger odds in exchange for a modest stake bump.
Presentation is sleek and modern: neon-lit gems, crisp particle effects, and audio cues that punctuate merges and multipliers. On mobile, the grid remains readable in both orientations and touch controls feel responsive. With an RTP configuration that can reach 97.25% and very high variance, this is a slot for UK players who enjoy patient build-ups and the thrill of “everything lining up” during an extended feature.
