Bonanza Billion Merge Up+ (BGaming): Merge Cascades, x100 Free Spins Multipliers and 15,000x Max Win
Published 9 October 2026. BGaming released Bonanza Billion Merge Up+ on 24 September, the sixth entry in its Bonanza Billion series. The fruit-and-gem look is the same one players have known for five years, but the cascade engine got a rebuild: winning symbols now merge into a symbol already sitting on the grid before they clear, which keeps cascade chains alive longer.

How it plays
The game runs on a 6x5 grid with a pays-anywhere system: 8 or more matching symbols anywhere on the reels pay out. After a win, the symbols clear and new ones drop in - but before they go, the Merge Up+ mechanic drops a copy of a winning symbol onto a spot already occupied on the grid. The more copies of that symbol are already in play, the better the odds the merge drops another one, which feeds the next cascade.
Multipliers stay out of the base game entirely. They live in the free spins round, triggered by 4, 5 or 6 scatters for 10, 20 or 30 spins. Multiplier symbols worth 2x to 100x can appear after tumbles or pop out of merges, and several of them add together at the end of a spin. Landing 3 or more scatters inside the round adds 5 extra spins. The round can also be bought outright for 100x the bet, and a Chance x2 mode doubles the odds of triggering it naturally.
