Boomberries

Our recorded Boomberries bonus

We have opened Boomberries once on 8 Jul 2026 on stream and logged the result. The best of them paid 0× the bet. That is too few open to say anything about how the game behaves — it is a record of what happened on that occasion, nothing more.

Elk Studios places Boomberries above the waterline this time, trading the studio's earlier underwater slot for a garden of oversized fruit, floating lanterns and a bomb-shaped little house with a lit fuse sitting in the background. The mood stays light throughout, carried by a cheerful soundtrack and a grid of watermelons, pineapples, strawberries, grapes and oversized berries.

The reels form a 6x7 cluster grid, and a win forms whenever five or more matching symbols land next to each other, up, down, left or right. Winning clusters clear from the board and the empty spaces refill from above, so one spin can chain several wins in a row if the drop keeps producing matches. Big symbols occasionally arrive in blocks of two, three or four squares across, filling several positions at once.

Five-symbol clusters return between 0.1x and 1x the stake, while the largest clusters of fourteen or more symbols climb to 10x-100x. There's no separate cast of premium characters here; most of the payout swing comes from cluster size rather than symbol rarity.

Boomberries' main engine is a set of multiplier features tied to specific grid positions. A position becomes a hot zone once it delivers its first win; the next win there adds a x2 multiplier, and further wins keep doubling it, up to a cap of x2,048 on a single spot. A collector symbol gathers up every visible multiplier value when it forms part of a win, while a separate dealer symbol takes its own multiplier — or a fresh x2 if it has none — and applies it outward across a triangular pattern of neighbouring positions, sometimes firing more than once in the same sequence.

A Hot Zone Strike can land on any drop, either planting a fresh x2 multiplier on a handful of random positions or doubling multipliers that are already there. Three wild types are in play: a standard wild, an Exploding Wild that clears pay symbols and triggers features in an X-shaped pattern without touching multipliers, and a Bomber Wild that copies a random symbol across that same X shape and does interact with the hot zone and multiplier system.

Three bonus scatters award ten free spins, and any multipliers built up beforehand carry into the round and stay active between spins. Landing three scatters together with a persistent multiplier already running upgrades the trigger into a super bonus, guaranteeing at least one multiplier feature stays active throughout the round, and two or three scatters appearing during the feature add another three or five spins on top.

An X-iter menu lets players skip ahead: 3x the stake buys a round with a better chance of triggering a bonus, 10x buys a guaranteed Hot Zone Strike, and 25x buys the persistent multiplier setup directly. The regular bonus can be bought outright for 100x, or the super bonus for 500x. Elk Studios has set the default RTP at 94%, paired with high volatility, a 25,000x maximum win and stakes running from 0.20 up to 100 per spin.
