Merge Up Slot Review

Merge Up Slot Overview

Merge Up is a 6x6 cluster slot from BGaming built entirely around shimmering gemstones and cascading wins. Instead of traditional paylines, you hit wins by landing four or more matching symbols in a cluster, which then trigger the Merge Up mechanic. Symbols upgrade through nine gem levels, setting off satisfying chain reactions. With an RTP of 97.25%, high volatility, and a max win of 5000x your stake, it instantly grabbed my attention.

When I first fired up Merge Up, the thing that stood out was how fast the grid can snowball from a small hit into a serious payout. Every winning cluster either disappears or climbs to a higher symbol level, while new gems fall from above. The gameplay feels punchy and direct, with no filler features, just a focus on merging symbols, free spins, and multipliers that can turn a single round into a highlight.

Get to know Merge Up Slot Rules

I always start a new slot by checking the numbers, and Merge Up ticks the boxes for a high-risk grid game. Bets range from 0.20 to 50 per spin, and you need at least four matching gems touching horizontally or vertically to score a cluster win. The stated hit rate is around 32.89%, so you can expect plenty of small to medium chains while waiting for the rare 5000x bursts the maths model can throw up.

Merge Up Slot Information

Visually, Merge Up keeps things clean with a green, gem-studded backdrop and the 6x6 grid taking centre stage. Every symbol is a different gemstone, which fits the cluster format nicely because it is easy to track upgrades as they merge. The interface is straightforward on both desktop and mobile, with bet controls below the reels and feature buttons such as Chance X2 and Bonus Buy placed beside the grid for quick adjustments.

The paytable in Merge Up is split into lower and higher paying symbols. Orange, red, green, and dark blue gems sit at the bottom, paying roughly 5x to 20x your stake for clusters of twelve or more. The premium set is yellow, light blue, red heart, and purple, worth about 25x to 50x for big clusters. There is no Wild, but the Scatter marked with an "S" acts as the ninth and highest merge level.

Merge Up Slot Features

The signature feature in Merge Up is the merging itself. Any time you land a winning cluster, some of those symbols are removed while others upgrade to the next gem level and stay on the grid. Fresh symbols drop into the gaps, and if new clusters form, the process repeats. With nine levels running from basic orange stones through to Scatter, big wins tend to come from chains of upgrades rather than single static hits.

Free Spins in Merge Up come from landing at least four Scatter symbols, anywhere on the grid. Four, five, or six Scatters award 15, 18, or 20 spins, and hitting the same numbers during the bonus adds 5, 8, or 10 extra spins. One neat twist is that if you form a cluster of the top level gem, that group can convert into a Scatter, which helps you reach the feature even from standard symbol wins.

During Free Spins, every position that forms part of a winning cluster gets marked, and that is where the real potential lies. If a marked cell is involved in another win, it gains a 2x multiplier on that specific spot, stacking up to 128x over the round. When a cluster pays, all multipliers on its cells are added together. Watching those marked positions grow across the grid is where the slot truly comes alive.

Detailed Merge Up Slot Features

Beyond the core merging and Free Spins, Merge Up offers a couple of extra switches that I find handy when I am chasing bonuses. Chance X2 costs an extra 0.25x on top of your current bet and increases the likelihood of Scatters dropping in, which speeds up access to the feature at the cost of slightly higher spin prices. It suits sessions where I am specifically hunting the Free Spins round.

There is also a Bonus Buy option priced at 100x your stake, giving you an immediate jump into Free Spins with four to six Scatters. On a high volatility slot like Merge Up, that can be a sharp way to target the top end of the paytable rather than grinding the base game. I like using it after a cold spell, when I am willing to trade balance swings for a shot at serious multipliers.

My verdict on Merge Up Slot

As someone who enjoys high variance cluster slots, Merge Up feels like a solid mix of straightforward rules and punchy features. The 97.25% RTP and clear 5000x ceiling keep the maths appealing, while the merging mechanic adds that satisfying sense of progression as gems climb the ladder. It can be swingy, and sessions without Free Spins do happen, but when multipliers line up on a busy grid, the game has real staying power.
