Boomberries online slot game
Boomberries is a cluster pays slot from ELK Studios that is about to be released in June 2026. Boomberries uses a 6x7 grid layout with an avalanche feature, Hot Zones multipliers, and a bonus where those multipliers persist between drops. This title is a reskinned version of the 2023 underwater-themed Oxygen slot by ELK Studios, set in a fruit forest environment. The multiplier engine underneath feels identical; the scenery has simply changed.

Boomberries Theme and First Impressions
In Boomberries, ELK Studios uses the visuals of enlarged fruits and animated bomb-creatures within a soft forest setting. The game feels cheerful and clean. Unlike the deep-sea setting in Oxygen Slot with many cartoonish characters, Boomberries is much more generic.
It does not have any complex story, but that’s just fine because fruit symbols are universal and do not get in the way of the gameplay mechanics. The X-Bomber and Exploding Wilds, represented by a pink bomb-creature and a teal one, respectively, are the slot’s most distinctive visual elements.

How Boomberries Plays – Base Game
The layout is simple: six columns and seven rows, cluster pays. To win, you need five or more matching icons to get connected either horizontally or vertically. When a win occurs, the winning icons disappear, and new ones appear in their places. This continues until no new winning combinations form. Big symbols – 2x2, 3x3, and 4x4 - may land during any drop, and on the grid this size, the 4x4 block is quite large.
The Hot Zone system drives the game. The first win in any position marks it. The second win activates the 2x multiplier, and each following win doubles until you reach 2,048x. In the base game, the multipliers get reset after each avalanche series is finished. It restricts the potential of the base game and creates an illusion of it being nothing but a waiting room.
The symbols are the following: a Strawberry (1x for 5 of the kind, 100x for 14+), a Pineapple (0.50x for 5, 50x for 14+), Watermelon (0.40x for 5, 30x for 14+), Blackberry (0.3 for 5, 25x for 14), and berries – blue, green, and yellow (0.10x-0.20x for 5, 10x-20x for 14+).

Boomberries Slot Bonus Features
Hot Zone Multipliers
Four mechanics are built on the Hot Zone:
- Hot Zones increase the multiplier of the winning positions by two
- Hot Zone Strike places 2x multipliers randomly anywhere on the grid or doubles the multipliers that already exist there
- The collector gathers all visible multipliers into its position
- The dealer spreads its position's multiplier across a V-shaped area of neighbours
In case the Collector and the Dealer are persistent inside the bonus game, a combination of them on a seeded grid is a possible way of hitting the 25,000x ceiling.
Wild Symbols
- Standard Wild – substitutes for any pay symbol
- X-Bomber Wild – selects a random symbol and replaces all pay symbols in an X-shape with it; activates Hot Zones and multiplier values within the shape
- Exploding Wild – removes all pay symbols in an X-shape above and below itself; clears the grid but does not activate Hot Zones or multipliers
The X-Bomber builds wins and multipliers; the Exploding Wild creates space – this matters in the bonus game.
Bonus Game
When three cherry Bonus symbols land on the grid, the Bonus Game with 10 drops activates. The multipliers remain in their spaces when they drop, which is the key difference from the base game. If 2 or 3 more scatters appear during the bonus game, they provide 3 or 5 extra drops, respectively. The bonus game can be retriggered. If three scatters appear with an active persistent multiplier, the activation of the trigger becomes Super Bonus, where at least one multiplier feature (Collector or Dealer) is guaranteed to be persistent throughout.
X-iter
- Bonus Hunt – 3x the stake, more than triple the chance to trigger the Bonus on that spin
- Hot Zone Strike – 10x, guaranteed Hot Zone Strike
- Persistent Multiplier Feature – 25x, guaranteed persistent multiplier feature
- Bonus – 100x, direct Bonus Game access
- Super Bonus – 500x, direct Super Bonus access
What to Expect When Playing Boomberries
The high volatility of Boomberries means that the main game regularly hits low payouts and rare high-paying cascades of avalanches, but longer scratches of dead spins. ELK Studios does not reveal information about trigger frequency.
Win Potential and Volatility
The max win potential is 25,000x. Achieving that requires a seeded field, a continuous Collector or Dealer, and a strong cluster. The maximum payout for each symbol position on the board is x2,048, but only very few players will see all of the above factors coming into play simultaneously. The Super Bonus produces the widest spread of outcomes; the standard Bonus is more consistent and more modest. With an RTP rate of 94%, the slot has one of the highest house edges among most comparators in this space.
Bet Range and Who It Suits
The bet range is €0.20 to €100. This title suits committed cluster pays players comfortable with high-volatility sessions. The X-iter range makes it accessible for selective feature buyers at lower stakes.
Mobile Performance
The Boomberries slot is fully browser-based; there’s no dedicated app. The 6x7 grid scales cleanly to portrait, with landscape mode preferable when tracking multiple Hot Zone multiplier values simultaneously. During our testing, the game performed smoothly on smartphones.
Boomberries Slot Alternatives
| Slot | Boomberries | Oxygen 2 | Sugar Rush 1000 |
|---|---|---|---|
| Developer | ELK Studios | ELK Studios | Pragmatic Play |
| RTP | 94% | 94% | 96.53% |
| Volatility | High | High | High |
| Max Win | 25,000x | 25,000x | 25,000x |
| Buy Feature | Yes, from 3x | Yes, from 3x | Yes, 100x / 500x |
| Min Bet | €0.20 | €0.20 | €0.20 |
| Max Position Multiplier | x2,048 | x2,048 | x1,024 |
| Key Feature | Collector + Dealer + Special Wilds | Jellyfish + Octopus | No wilds, 7x7 grid |
The Sugar Rush 1000’s RTP is a meaningful advantage for organic play. If you consider RTP an important factor in game choice, Sugar Rush 1000 is more suitable. In Oxygen 2, randomness in terms of multiplier distribution is introduced by the Jellyfish and Octopus features. Boomberries gameplay feels more strategic thanks to Collector and Dealer features.
Verdict – Is Boomberries Worth Playing?
Boomberries delivers what ELK Studios does well: persistent Collector and Dealer interactions that feel genuinely escalating, and X-Bomber Wild that Sugar Rush 1000 cannot match. The hard argument against it is the 94% RTP. Oxygen veterans won’t find anything new in this title aside from the fresh visuals.
Boomberries are worth the play for bonus hunters buying the X-iter Bonus or Super Bonus selectively. If you’re more into organic sessions on a real budget, Sugar Rush 1000 is the better value.
