Merge Up: Cluster Pays, Merging Gems and a 97.25% RTP
Merge Up from BGaming has no reels in the classic sense. It plays on a 6x6 grid where clusters of matching gems form wins. The thumbnail shows a rainbow-cut stone, and gems that merge into higher tiers are the heart of the game. Of all the titles we cover, Merge Up has the highest RTP published by its studio.
Merging and clusters
A win forms when enough identical symbols touch horizontally or vertically, regardless of lines. On top of that, matching gems merge into a higher-value symbol. Cells where a win happened can gain sticky multipliers that stay in place and boost further wins on the same cell. Free spins amplify the mechanic.
For the player this means value concentrates in the moments when multipliers pile up on the grid. Ordinary spins are modest; what matters is what happens when multipliers meet a big cluster.

A high RTP does not mean a quick win
An RTP of 97.25% is above average: the theoretical cost of play is €2.75 per €100 staked, less than a typical margin on main football markets. Very high volatility, however, says the spread of outcomes is wide — a lower average price does not mean the win comes sooner. It is like a fairly priced bet on an outsider: good value, but most of the time it loses.
A practical example on €40: a €0.20 stake gives 200 spins and room to reach the free spins. At €2 a spin you have twenty tries — too few for a game whose value hides in rare moments.
Watching the grid without illusions
The merging mechanic easily creates the feeling that the grid is “charging up” and a win is close. Sticky multipliers really do stay on their cells during a phase of the game, but that does not raise the probability of a big cluster on the next spin beyond what the maths allows. A simple log helps more: how much went into the session, how much came out and how long it lasted. After a few sessions you will see how the game swings in practice and can adjust the stake — the same habit we recommend for recording bets.
