Merge Up

Match-3 logic meets high-stakes slot mechanics: Merge Up by BGaming drops a 6x6 cluster-pays grid where symbols do not just win and disappear: they level up. Four or more adjacent identical gems form a cluster, collect the win, then the survivors merge into a higher-tier symbol, potentially triggering another cluster in a chain reaction. At 97.25% RTP and very high volatility, the ceiling is 5,000x, and the Cell Multiplier system can push a marked cell to x128 by the end of a free-spin run. Available at Wild.io across desktop and mobile with crypto.

What is Merge Up?

Merge Up is a 6x6 cluster-pays video slot from BGaming with a 97.25% RTP, very high volatility, and a 5,000x max win, built around a nine-level symbol progression system where clusters pay out and then merge into higher-value gems.

The standout mechanic is the merge cascade: when 4 or more identical symbols sit adjacent, they form a winning cluster, some symbols disappear, and the remaining ones upgrade one tier. Nine symbol tiers sit below the Scatter, and level-8 clusters trigger Bomb symbols that clear eight surrounding cells before converting to Scatters. Cell Multipliers mark the sites of previous wins and double on each subsequent hit in the same cell, growing up to x128 and transforming big cluster chains into exponentially larger payouts.

How To Play Merge Up Slot - Step By Step

Head to Wild.io and create a free account to start playing Merge Up.

1. Open Merge Up at Wild.io and set your stake across the 6x6 grid
2. Symbols drop onto the grid; clusters of 4 or more adjacent identical gems pay out immediately
3. After a cluster win, some symbols in the winning group disappear and the remaining ones level up to the next symbol tier, potentially forming new clusters
4. Cells where clusters formed are marked as Cell Multiplier cells; subsequent wins in those cells start at x2 and double with each repeated hit, reaching up to x128 in a single cell
5. When level-8 symbols form a winning cluster, a Bomb symbol appears, explodes and removes the 8 surrounding cells, then converts to a Scatter
6. Collect 3 or more Scatter symbols in a single spin to trigger up to 30 Free Spins, during which all existing Cell Multipliers carry over and continue compounding

You can also deposit using various supported payment methods.

Merge Up Slot Theme & Graphics

Merge Up takes visual cues from mobile casual gaming: colorful geometric gem symbols arranged on a clean grid, with each symbol tier rendered in a distinct color and shape so the progression from level 1 through level 9 is always legible at a glance. BGaming designed the board to feel like a game board rather than a slot cabinet, and the merge animations communicate value clearly as lower gems consume each other and produce a higher-level form.

The color palette runs from cool blues and greens at the lower tiers through warm oranges and reds toward the top, with the Bomb symbol's metallic black standing apart from all nine gem tiers. Sound design mirrors the visual language: each successful merge lands a distinct chime tone that rises in pitch with the symbol tier, so a long cascade chain produces a rising auditory sequence that reflects the mathematical escalation on screen.

Merge Up Slot Symbols & Paytables

Merge Up replaces traditional named symbols with a tier system: nine levels of gems plus the Scatter. Understanding the symbols means understanding the slot-machine symbols as a progression ladder rather than a fixed paytable, since the value of any cluster depends on its tier at the moment it wins.

Low Value Symbols

Symbol tiers 1 through 4 form the lower end of the progression. These are the smallest gem shapes on the grid, rendered in blue and green tones, and they constitute the majority of starting symbols on any spin. At tiers 1 and 2 the cluster payout is modest; the value comes from what they become rather than what they pay in their current form. A cluster win at tier 2 means some of those symbols merge into tier-3 gems, and if a new cluster forms at tier 3, those in turn can merge up again. The chain potential of the low tiers is therefore significant: a board that starts with many level-1 symbols can cascade through three or four upgrade steps in a single drop sequence, each step paying progressively more and marking new Cell Multiplier cells in the process.

High Value Symbols

Tiers 5 through 9 represent the upper end of the symbol hierarchy. Tier 5 and 6 gems arrive in warm amber and orange and begin to carry cluster payouts meaningful in absolute terms rather than purely as merge fuel. Tier 7 and 8 symbols appear only as the product of previous merges within the same spin sequence; landing them pre-formed on a fresh drop would require a very specific board configuration. The tier-8 gem is the critical one: when four or more adjacent tier-8 symbols form a cluster, the game does not simply merge them into tier 9. Instead, a Bomb symbol is created at the merge point, and its explosion mechanic fundamentally changes the board state before the next cascade step.

Special Symbols

The Bomb symbol is the only special symbol with an action effect other than the Scatter. It appears only when a tier-8 cluster wins, then immediately explodes and clears the 8 symbols surrounding it. Those cleared spaces refill with new symbols, and the Bomb itself converts into a Scatter. This means a single cascade chain can generate multiple Bombs in sequence if repeated tier-8 clusters form, each detonation potentially exposing new Scatter positions and extending the chain. The Scatter (which is effectively tier 10 in the hierarchy) has one function: collecting 3 or more in a single spin or cascade sequence triggers the Free Spins bonus. During Free Spins, any Cell Multipliers already marked on the grid carry into the bonus, and the x2-to-x128 doubling mechanic continues applying across all bonus spins.

Merge Up Bonus Feature & Special Features

Cluster Pays Merge Mechanic

Merge Up's core mechanic replaces paylines entirely with a cluster-pays system on the 6x6 grid. Four or more identical symbols touching horizontally or vertically form a valid winning cluster; the game pays the cluster value immediately, then removes some symbols from the cluster while the remaining ones upgrade to the next tier. This triggers a cascade: new symbols drop into empty spaces, and if the upgraded symbols or new arrivals form a fresh cluster, it pays and continues the merge chain. Because there are 9 symbol tiers, a chain that starts with tier-1 clusters can theoretically cascade all the way to tier-8 Bomb triggers in one sequence. The very high volatility profile of Merge Up is a direct product of this structure: most spins produce modest or no wins, but the rare sessions where a cascade chain sustains itself across multiple tiers generate the large multiples that drive the 5,000x max win.

Cell Multipliers

Every cell where a winning cluster has formed is flagged with a multiplier marker. The first time a new cluster includes a marked cell, that cell's multiplier is set to x2. Each subsequent winning cluster in the same marked cell doubles the multiplier again, continuing until the cell reaches the maximum of x128. The multiplier is applied to the payout of any cluster win that overlaps that cell, so a large cluster covering several marked cells with different multiplier values combines all of them. During Free Spins, the multipliers accumulated in the base game carry over and continue doubling, which is why the bonus round disproportionately accounts for the top end of the payout range. Managing where clusters form and which cells have already been marked is part of what makes Merge Up feel more strategic than a standard slot.

Bomb Symbols

A Bomb symbol is created specifically when a tier-8 cluster wins. After the win is paid, a Bomb appears at the merge point. The Bomb immediately detonates, removing the 8 symbols immediately surrounding it from the grid. Empty cells refill with new symbols, which may form new clusters on their own or combine with surrounding symbols for another cascade step. After detonating, the Bomb converts to a Scatter symbol. This mechanic serves two functions simultaneously: it clears a portion of the board to make room for higher-tier symbol formation, and it seeds an additional Scatter that contributes toward the 3-Scatter threshold for triggering Free Spins.

Free Spins

Collecting 3 or more Scatter symbols in a single spin or cascade sequence triggers the Free Spins bonus. The number of free spins awarded scales with the Scatter count: 3 Scatters yields a base allocation, and each additional Scatter above 3 adds more spins, up to 30 Free Spins at the maximum. The key feature of the Free Spins round is continuity with the base game's Cell Multiplier state: any marked cells and their current multiplier values carry directly into the bonus. This means that a base game that ends with several cells already marked at elevated multipliers carries those values directly into Free Spins, and every new cluster win in a marked cell doubles the value again. Jackpot-range outcomes in Merge Up almost always involve Free Spins sessions where multiple cells reach the x128 cap and several clusters overlap marked cells simultaneously.
