Merge Up is a very high-volatility grid slot developed by BGaming, built on a 6x6 Cluster Pays layout combined with an innovative merge-based symbol progression system. Featuring Free Spins with progressive cell multipliers and a max win of 5,000x your bet, this title stands out as one of the most compelling releases in BGaming's growing portfolio.
Launched in 2023, Merge Up has firmly established itself as one of the most talked-about slots in BGaming's catalogue — and it's easy to see why. Drawing heavy inspiration from mobile casual gaming, the slot replaces traditional paylines with a 6x6 cluster grid where matching gems combine, level up, and trigger explosive chain reactions across the board.
"We are always looking to keep on top of the latest trends of online gaming, and this is why we are excited to launch Merge Up, which is the first in what we plan to be a collection of merging mechanic games. We know our players enjoy the gamification of our slot portfolio, so observing what works in mobile gaming and bringing it to the iGaming landscape seemed a natural progression for us. We can't wait for players to enjoy it." — Julia Alekseeva, CPO, BGaming

Merge Up keeps its visual presentation deliberately clean and minimal, mirroring the aesthetic of popular mobile gem-crush games. The 6x6 playing board is packed with bold, shiny crystals in various shapes and colours, all set against a sleek green backdrop. Despite the stripped-back design approach, the production quality is genuinely impressive — graphics are crisp and detailed, animations run silky smooth, and the upbeat soundtrack perfectly complements the lighthearted, energetic tone of the game.
At the heart of the Merge Up online slot is the Cluster Pays mechanic, which governs how winning combinations are formed. The game unfolds on a 6x6 grid, where wins are awarded when 4 or more matching symbols appear adjacent to each other horizontally and/or vertically. This system is deeply intertwined with the cascading and merging mechanics that define the slot's core experience — both of which are explored in detail in the sections below.
The betting structure is designed to accommodate a wide range of players, from casual spinners to high-stakes enthusiasts.
Merge Up keeps its feature set purposefully focused, with the bulk of the excitement driven by its inventive core merging system. Symbol upgrades and cascading chain reactions dominate the base game experience, while a dedicated Free Spins round elevates the action further through a progressive multiplier system that will feel familiar to fans of cluster-pays titles.
The defining mechanic in Merge Up is its symbol progression system. Whenever 4 or more identical gems land adjacent to one another — horizontally or vertically — they form a paying cluster. Once that cluster is evaluated and the win is awarded, part of the cluster disappears from the grid, while the remaining positions are upgraded into the next symbol tier, effectively merging the win into more powerful gems ready to fuel further reactions.
Key points about how the merge system works:
Larger clusters therefore leave behind more upgraded gems, significantly increasing the probability of follow-up merges on the same spin and creating the potential for long, rewarding chain reactions.
The Free Spins feature is triggered when 4 or more Scatter symbols appear anywhere on the grid simultaneously. The number of spins awarded scales with the Scatter count:
The Scatter symbol occupies the highest tier in the symbol hierarchy — level 9 — meaning it doesn't only appear at random. It can also be created organically during gameplay when a cluster reaches the top merge level, converting that position into a Scatter.
What truly sets this bonus round apart is its progressive cell multiplier system:
The round can also be extended mid-feature: landing additional Scatters during Free Spins adds extra spins to the counter:
For players who prefer not to wait for the bonus to trigger organically, Merge Up offers two shortcut options:
Merge Up comes with very high volatility, meaning winning spins arrive less frequently during regular gameplay — but when the grid aligns and the merge chains start flowing, payouts can scale sharply and dramatically.
