Merge Up

Merge Up by BGaming is a video slot that plays on a 6×6 grid and uses cluster pays rather than traditional paylines. The symbols are gemstones in nine levels, and when four or more identical gems touch horizontally or vertically they form a winning cluster. After a win, some symbols disappear and others merge into a higher-level gem, possibly triggering cascades and eventually producing the top-level symbol that serves as the Scatter. Free Spins are triggered by landing four, five, or six Scatter symbols anywhere in view: that gives 15, 18, or 20 free spins respectively. During Free Spins, every cell involved in a winning cluster becomes marked; if that same cell is part of further wins it gains a 2× multiplier each time, doubling with each win up to a maximum of ×128; these marked cells remain for the duration of the Free Spins round. There is a Buy Bonus feature (where available) allowing direct access to the Free Spins round at a cost that adjusts with the bet. There is also a Chance ×2 option which increases the bet slightly in order to boost the chance of triggering Free Spins naturally. The theme is simple and clean: magical gemstones set against a green, gem-crystal style backdrop, focused more on the evolving board than elaborate characters.
