Boomberries

Boomberries: The Short Version

Boomberries is ELK Studios' fruit-flavoured, cluster-pays slot, spun off from the studio's earlier underwater release Oxygen and rebuilt above ground with a mountain of berries, grapes, and melons instead of sea creatures. It's a 6-reel game that trades paylines for adjacency clusters and grid-based multipliers.

Theme & Gameplay Feel

Visually, Boomberries goes for a lightly magical orchard vibe: oversized fruit, floating lights, and a bomb-shaped little house with a lit fuse sitting in the background. It won't win points for originality — ELK has clearly reused mechanical bones from Oxygen — but the cheerful soundtrack and mellow pacing make it an easy, relaxed slot to settle into. The playing field spans 6 reels by 7 rows, and wins form whenever five or more matching fruit symbols land adjacent to one another. Winning clusters clear from the grid, new symbols drop in, and the process repeats as long as fresh clusters keep forming.

RTP: What 94% Delivers

Boomberries returns 94.0% to players over the long haul, meaning £94 comes back for every £100 wagered across the wider player base. That's slightly below the very best RTP figures on the market, but still within a normal, acceptable range for a feature-rich cluster slot.

Volatility and What to Expect

This is a high-volatility game, and the fruit clusters reflect that swingy nature — a 5-of-a-kind cluster only nets 0.1x to 1x the bet, but stack 14 or more matching symbols together and payouts jump to 10x-100x the stake. Big 2x2, 3x3, and 4x4 symbols occasionally land too, adding extra unpredictability to each drop.

Max Win and Betting Range

The headline number is a 25,000x max win, a genuinely serious ceiling built from the game's stacked multiplier features, Hot Zone Strike mechanic, three separate wild symbols, and both a bonus game and a super bonus game layered on top of the base cluster action. Stakes run from 0.20 up to 100 per spin, giving plenty of room to scale bet size to bankroll.

How It Compares to ELK's Back Catalogue

Players who've already spent time with Oxygen will recognise the underlying grid multiplier system almost immediately, right down to the doubling mechanic on consecutive wins. Boomberries doesn't try to hide that lineage, but the above-ground fruit theme and Hot Zone Strike addition give it just enough of its own identity to stand apart from a straight reskin.

Verdict

Boomberries won't surprise anyone who's already played ELK's back catalogue, but the combination of a chunky 25,000x ceiling, high volatility, and layered multiplier features still makes for an entertaining grind once the avalanches get going.
