Cluster Pays (4+ adjacent symbols)
Ever played one of those mobile merge games where two things combine into a bigger thing, then two of those combine again? Merge Up 2 from BGaming borrows that exact loop and bolts it onto a 6×6 cluster-pays slot. Group four or more matching gems side by side (up or down, not diagonally), and instead of just paying out and vanishing, the survivors fuse into the next symbol up the ladder. There are nine levels in total. You start with humble little gems and work toward the star.
Here's what makes the sequel worth a look. Every cell where a win lands gets tagged. Win on a tagged cell again and it earns an x2 multiplier, then x4, then x8, doubling all the way up to a ceiling of x128 on a single square. In the first Merge Up, this trick was locked to the bonus. Now? It runs in the base game and the free spins alike. That's the real upgrade.
Push a cluster to the 8th level and it spawns a bomb. The bomb detonates, wipes the eight cells around it, bumps their multipliers a notch, and morphs into a scatter. Collect three scatters and you're into free spins: 12 for three, 15 for four, 20 for five, 30 for six or more. Multipliers you've built don't reset. They ride the whole round.
Impatient? Three buy options let you skip ahead, priced at 100x, 250x, or 500x your stake, the last one seeding the reels with pre-placed bombs. A Chance x2 ante nudges your trigger odds if you'd rather not buy outright.
The math is steep. RTP sits at 97% and volatility is rated very high, so dry stretches are part of the deal, and the candy-bright visuals can feel a touch juvenile if that's not your thing. But the top prize is a full 10,000x, and watching a corner of the grid snowball into a x128 cell is genuinely tense. It landed in October 2025.
