Boomberries is ELK Studios doing what they do best — building a distinct mechanical identity around a strong visual concept. The 25,000x max win is exceptional for a 6-reel Cluster Pays format and positions the game among the highest-ceiling ELK releases in recent years. The 94% RTP is the clear trade-off: it sits below the 96% industry benchmark and players should factor that into their bankroll expectations. What ELK consistently delivers is a bonus round that earns its ceiling — and based on the pre-release build, Boomberries is on track to do the same. Recommended for High volatility players who prioritise ceiling over long-run return.

Boomberries is an upcoming High volatility slot from ELK Studios, scheduled for June 24, 2026. ELK is a Swedish provider with a strong track record of mechanically innovative releases — titles like Nitropolis and Cygnus demonstrated their ability to push the format beyond standard cluster pays templates. Boomberries brings an explosive berry theme to a 6-reel Cluster Pays grid, where the "Boom" mechanic — based on pre-release materials — triggers chain-reaction explosions that clear symbols and sustain cascade sequences.
Key stats: 94% RTP, High volatility, 25,000x max win, 6 reels, Cluster Pays, $0.20–$100 bet range. The 25,000x max win is the headline figure — it places Boomberries among ELK's highest-ceiling releases and is competitive with the top tier of cluster pays titles from any provider. The 94% RTP is the acknowledged compromise: ELK redirects the theoretical return into peak-win potential, a trade-off common across their high-ceiling catalogue. The $0.20 minimum bet keeps the game accessible despite the ambitious ceiling.
Boomberries — base game.
The core Boomberries mechanic triggers explosive chain reactions when berries cluster on the 6-reel grid. Each explosion clears surrounding symbols and enables new symbols to fall into place, extending cascade sequences beyond what standard cluster formation would allow. This creates multi-stage win events within a single spin — ELK's signature approach to volatile return distribution.
Six reels give Boomberries a wider win surface than the 5-reel standard, creating more space for multi-cluster formations and extended cascade chains. Cluster Pays removes fixed paylines in favour of symbol adjacency — winning combinations form wherever matching symbols connect horizontally or vertically. This format rewards full-grid coverage and penalises isolated symbol placements.
The 25,000x ceiling is exceptional — at $0.20 minimum bet that's $5,000, and at $100 maximum it reaches $2,500,000. ELK's approach to max win delivery involves multiplier accumulation through cascade chains during bonus rounds, where each successive wave builds the multiplier to the point where a premium cluster completes the ceiling outcome.
ELK Studios applies a consistent philosophy across their high-ceiling titles: compress the long-run return to fund a higher peak-win multiplier. At 94%, Boomberries sits 2 percentage points below the 96% industry benchmark. For players who play short, high-variance sessions targeting the bonus round, this is an acceptable trade. For high-volume grinders, the RTP gap matters.
The Boomberries pre-release demo captures the essence of what makes ELK's cluster pays format compelling. The 6-reel grid produces base-game clusters regularly enough to sustain engagement, and the boom explosion trigger — when it fires — visibly extends cascade chains beyond what a passive cluster pays grid would produce on its own. The explosions add a kinetic quality to each spin that differentiates the game from static cluster competitors. Base-game win sizes are moderate; the game makes no pretence of delivering value outside the bonus.
The bonus trigger frequency felt consistent with High volatility expectations — not immediate, but not brutal either. When the feature fires, the cascade-plus-explosion combination creates rapidly accelerating win stacks that are visually and mechanically satisfying. The multiplier build during bonus rounds is the primary vehicle for reaching meaningful totals. Early demo play across extended sessions showed bonus rounds ranging from routine (2–5x stake) to genuinely exciting multi-cascade chains that approached triple-digit multipliers.
The ELK polish is evident throughout — animations, sound design, and the responsiveness of the grid during explosion chains all deliver above the market average. For the June 24 release, the mechanical profile aligns with the 8/10 Recommended verdict: the 25,000x ceiling is real, the bonus mechanics earn it, and the 94% RTP is the price you pay for a slot built around outlier outcomes rather than balanced long-run return.
Boomberries — bonus round.
Boomberries earns an 8/10 from SlotArk — Recommended. ELK Studios' explosion mechanic, 25,000x max win, and 6-reel Cluster Pays format make it a standout pre-release for June 2026. The 94% RTP is the main trade-off — accept it going in and this is one of the most exciting High volatility demos of the season.
Boomberries has an RTP of 94% — below the 96% industry average. This is intentional: ELK Studios channels the theoretical return into the 25,000x max win ceiling. Always check your casino's configured RTP before playing for real money.
The max win is 25,000x your stake — $5,000 on a $0.20 minimum bet, or $2,500,000 on a $100 maximum bet.
