Boomberries online slot review
Evan Carrington's review for Casino Ideal describes Boomberries as a cluster-pays slot from ELK Studios, scheduled for release in June 2026. Its 6x7 grid combines avalanches with Hot Zone multipliers and a bonus mode where those multipliers persist between drops. Set in a fruit-filled forest, it is a reskinned take on ELK Studios' 2023 underwater-themed Oxygen slot. Behind the new scenery, the multiplier engine feels much the same.

Boomberries theme and first impressions
In Boomberries, ELK Studios sets oversized fruit symbols and animated bomb-like creatures against a peaceful forest backdrop. The presentation is bright and uncluttered. Unlike Oxygen Slot's deep-sea setting, with its many cartoon characters, Boomberries feels much more generic.
There is no elaborate story, but that is not a major drawback: familiar fruit symbols keep the focus on the mechanics. The pink X-Bomber and teal Exploding Wilds are the game's most distinctive visual features.
Top casinos to play Boomberries:
How Boomberries plays – base game
Boomberries has a straightforward six-column, seven-row cluster-pays layout. To win, five or more matching icons must connect horizontally or vertically. Winning icons disappear, replacement symbols drop into the empty spaces, and the sequence continues as long as new combinations form. Large 2x2, 3x3 and 4x4 symbols can arrive on any drop; on this grid, a 4x4 block takes up a considerable area.
Hot Zones are the game's central mechanic. A position is marked after its first win; a second win activates a 2x multiplier, and each further win doubles the value up to 2,048x. In the base game, the multipliers reset at the end of every avalanche sequence. This limits the base game's potential and can make it feel like a warm-up for the main event.

Boomberries slot bonus features
Hot Zone multipliers
Hot Zones power four distinct mechanics:
- Hot Zones double the multiplier attached to winning positions
- Hot Zone Strike randomly adds 2x multipliers to the grid or doubles values already at those positions
- The Collector gathers every visible multiplier into its own position
- The Dealer spreads the multiplier at its position across a V-shaped group of neighbouring spaces
When the Collector and Dealer persist in the bonus game, landing both on a suitably seeded grid can offer a route towards the 25,000x cap.
Wild symbols
- Standard Wild – substitutes for any paying symbol
- X-Bomber Wild – picks a random symbol, fills the paying-symbol positions in an X pattern with it, and activates Hot Zones and multipliers within that pattern
- Exploding Wild – clears the paying symbols in an X pattern above and below itself; it opens up the grid without activating Hot Zones or multipliers
The X-Bomber builds wins and multipliers, while the Exploding Wild clears space; this difference matters in the bonus game.
Bonus Game
Three cherry Bonus symbols trigger the Bonus Game, which starts with 10 drops. Multipliers stay in place as symbols fall, the main difference from the base game. Landing 2 or 3 more scatters during the bonus adds 3 or 5 drops, respectively, and the mode can retrigger. If three scatters land while a persistent multiplier is active, the trigger upgrades to Super Bonus; at least one Collector or Dealer feature is then guaranteed to remain persistent throughout.
X-iter
- Bonus Hunt – costs 3x the stake and gives more than triple the chance of triggering the Bonus on that spin
- Hot Zone Strike – costs 10x and guarantees Hot Zone Strike
- Persistent Multiplier Feature – costs 25x and guarantees a persistent multiplier feature
- Bonus – costs 100x and provides direct access to the Bonus Game
- Super Bonus – costs 500x and provides direct access to Super Bonus
What to expect when playing Boomberries
Boomberries' high volatility can mean frequent low-paying base-game results, occasional high-paying avalanche runs and long stretches without a win. ELK Studios does not publish the trigger frequency.
Win potential and volatility
The stated maximum win is 25,000x. Reaching it would require a seeded grid, a Collector or Dealer that stays active, and a strong cluster. Each symbol position can reach x2,048, but the review notes that very few players will see all these conditions align. Super Bonus offers the widest range of outcomes, while the standard Bonus is relatively steadier and more restrained. With a 94% RTP, the slot has a higher house edge than many comparable games in this category.
Bet range and who it suits
Bets range from €0.20 to €100. Boomberries is aimed at cluster-pays fans who are comfortable with high-volatility play. Its X-iter options also offer selective feature access at lower stakes.
Mobile Performance
Boomberries runs in a browser, not a dedicated app. The 6x7 layout fits portrait screens well, though landscape orientation is better for keeping track of several Hot Zone multipliers at once. The review reported smooth smartphone performance during its testing.

Sugar Rush 1000's RTP is presented as a notable advantage for regular play. If RTP is a key consideration, Sugar Rush 1000 may be a closer match. Oxygen 2 adds randomness to multiplier placement with its Jellyfish and Octopus features, while Boomberries may feel more strategic thanks to its Collector and Dealer mechanics.
Verdict – is Boomberries worth playing?
Boomberries highlights some of ELK Studios' strengths: Collector and Dealer interactions that build a sense of momentum, as well as an X-Bomber Wild not found in Sugar Rush 1000. The main concern is its 94% RTP. Players familiar with Oxygen should not expect a substantially different game beyond the refreshed visuals.
The review recommends Boomberries to bonus hunters who selectively buy the X-iter Bonus or Super Bonus. For players looking for regular play on a tight budget, it considers Sugar Rush 1000 the better-value choice.
