Merge Up: a cluster slot where gems grow into bigger gems
Merge Up is a BGaming slot played on a 6x6 grid with cluster pays. Matching gems that touch form a winning cluster, and the twist is in the name: clusters can merge into a gem of a higher tier. BGaming lists an RTP of 97.25%, very high volatility and a top win of 5,000x the stake. Whether the game is in the Cardwin lobby right now, and in which configuration, is something to confirm with the operator.

How a spin plays out
Think of the grid as a board game rather than a set of reels. After the drop, the game looks for groups of the same gem that are connected side by side. Each qualifying group pays and disappears, new symbols fall in, and the board is checked again. When gems merge, the reward is not only the payout of the moment but a stronger symbol on the board that may feed the next cluster.
What sets it apart
Most cluster slots treat every cascade the same. Merge Up adds memory to the board: according to the studio, some cells keep a multiplier that sticks, so wins landing on those positions are boosted. In the free spins round those multipliers have more time to build. That is where most of the game's value tends to sit — and why the base game can feel quiet.
Reading the volatility rating
A 97.25% RTP is on the generous side, but it says nothing about the shape of your session. "Very high volatility" means the payout distribution is lopsided: lots of small or empty rounds, occasional large ones. If your bankroll is small relative to your stake, you may never reach the rounds where the RTP is concentrated. Lowering the stake buys you more spins, which is the only lever you control.
Check the info panel first
Operators can run different RTP configurations of the same title. Open the game's info or rules panel and confirm the RTP, the bet range and how the bonus round triggers before you stake real money. If a demo mode is offered, a few minutes of free play will show you the rhythm of the merges better than any description.
Play within limits
Set a session budget and a stop time before the first spin, and use the deposit or loss limits the operator provides. Free, confidential support is available from Gambling Therapy. More tools are listed on our responsible gambling page.
