Merge Up 2 (BGaming) Slot Review

Merge Up 2: Slot Overview

Merge Up 2 is a cluster-pays slot from BGaming, released in 2025. Developed in collaboration with Strmlytics, it features a casual gem-merging theme inspired by mobile puzzle games like Candy Crush Saga. The game uses a 6×6 grid where wins form from 4 or more adjacent symbols horizontally or vertically, with cascading reels that merge winning gems into higher-value ones, building position-based multipliers. Targeted at players seeking straightforward, high-RTP cluster slots with high volatility and explosive potential up to a 10,000x max win, it appeals to fans of merging mechanics and persistent features across base and bonus play.

Design and Graphics

The visuals in Merge Up 2 adopt a clean 2D aesthetic with a turquoise tiled background that keeps the focus on the central 6×6 grid filled with colorful gem symbols. Graphics evoke mobile match-3 games, featuring simplified, vibrant icons differentiated by shape and color—ranging from a low-paying 2-corner tear drop to a high-paying 3D-like purple diamond—ordered by the number of angles. The layout is intuitive: symbol hierarchy displayed above the grid, feature buy buttons on the left, win history on the right, and no unnecessary clutter. Animations are smooth during cascades, merges, and explosions, with gems sparkling and transforming crisply. Bombs detonate with a radial blast effect destroying nearby symbols, while scatters shimmer in multi-color patterns. The design is fully mobile-optimized, ensuring seamless performance across desktops, tablets, and smartphones, prioritizing functionality over flashy 3D effects for a contemporary, distraction-free experience.

Gameplay Mechanics

Merge Up 2 employs a 6×6 grid with no fixed paylines, instead using a cluster-pays system where wins require 4 or more identical symbols adjacent horizontally or vertically. After a win, some symbols in the cluster merge and upgrade to the next higher symbol in the hierarchy, while others cascade away; new symbols then drop in to fill empties, with the number added based on cluster size: 2 for 4-5 symbols, 3 for 6-7, 4 for 8-9, 5 for 10-11, and 6 for 12+. This process repeats as long as new clusters form.

Each winning cluster highlights positions with a white mark, activating a Position Multiplier that starts at x1 on the first hit, doubles to x2 on the next, and continues doubling up to x128 per position. Multi-position clusters multiply payouts by the sum of those values. The paytable includes 8 regular gem symbols paying 0.08x to 0.8x the bet for clusters of 4 and up to 4x to 80x for 12+, alongside special symbols: the Bomb (triggers from top-symbol clusters, explodes 8 surrounding symbols, advances their multipliers by one step, then becomes a Scatter) and the organic Scatter (multi-color star).

Base game flow emphasizes chaining cascades, merges, and multiplier builds for escalating wins, with a hit frequency of 29.41%.

Bonus Features

The core mechanics extend into bonuses via Scatters and Feature Buys. Landing 3, 4, 5, 6, or more Scatters at spin’s end awards 12, 15, 20, or 30 Free Spins, respectively; 3+ retriggers add 5 more. In free spins, Position Multipliers persist across spins up to x128, allowing continuous buildup. Bombs function identically, exploding for area clears and multiplier bumps before converting to Scatters.

Betting Options and Payouts

Bets range from €0.25 to €25, accommodating casual and higher-stakes play. The default RTP 98% is exceptionally player-friendly, paired with high volatility for infrequent but substantial payouts. Regular symbols scale from 0.08x (4-of-a-kind low gems) to 80x (12+ high gems), amplified by merging and multipliers. Max payout caps at 10,000x the bet, driven by cascading chains, position sums up to x128, and bonus persistence.
