Play Boomberries

Fruit has rarely appeared this ready to explode. Boomberries by ELK Studios lands at Heart Bingo with a 6x7 cluster grid, bright village scenery and a feature setup that may feel rather familiar to anyone who has seen Oxygen in action. 

Instead of paylines or ways, this release builds potential wins through connected fruit clusters. Hot Zones, avalanches, large symbols, special Wilds, Collector and Dealer effects all join the mix, so the cheerful background is doing a lot of smiling while the grid handles the actual chaos. 

Boomberries takes place in a soft, colourful village where enormous fruit sits around winding paths, green hills and rounded houses that look suspiciously like bombs. The setting has a fairy tale quality, though the fruit is large enough to suggest the local gardening club has been keeping secrets. 

The 6x7 grid sits in the centre inside a natural wooden frame. Glossy fruit symbols stand out clearly against the background, with strawberries, pineapples, watermelons, grapes and smaller berries all using strong colour contrast. Big Symbols are easy to spot because they cover several grid positions at once, while Wild effects bring flashes, blasts and symbol changes during avalanches. The soundtrack keeps things light, and the background stays mostly calm. Most of the movement comes from the grid, where falling symbols and multiplier frames do the useful work. 

Boomberries uses a cluster pays system, so values depend on the size of the connected symbol group. The smaller berries sit at the lower end, while strawberry gives the highest regular potential payout. 

• Wild: Regular Wilds replace paying fruit symbols and help complete cluster wins. 
• Exploding Wild: This Wild removes symbols in an X shape around its position. New symbols then drop into the cleared spaces. 
• X Bomber Wild: The X Bomber Wild changes symbols in an X shape into one matching paying symbol or additional Wilds. 
• Bonus Symbol: Cherry Bonus symbols trigger the Bonus Game when three are present on the grid at the end of a base game round. 
• Collector: The Collector gathers active Hot Zone multiplier values and adds them to its own value. 
• Dealer: The Dealer multiplies position values in a V shaped pattern facing left, right, upward or downward. 

Avalanche 

Every winning cluster disappears from the grid once the potential payout has been calculated. The remaining symbols fall into the empty spaces, and fresh symbols enter from above. 

This process continues while new winning clusters appear. Because Hot Zones depend on positions used by previous wins, avalanches can gradually turn certain cells into far more important spaces. 

Big Symbols 

Any paying fruit can appear as a 2x2, 3x3 or 4x4 Big Symbol. Each covered position counts as part of that symbol, which can quickly increase the cluster size. 

A large fruit may also separate during an avalanche, allowing pieces to fall into new positions. That creates a useful link between size, movement and the Hot Zone system. 

Hot Zones 

After a winning cluster forms, every covered grid position becomes highlighted as a Hot Zone. If another winning cluster uses one of those positions during the same round, the multiplier on that cell doubles. 

This is where Boomberries most clearly follows the trend seen in other online slots built around position multipliers. The maximum value for a single position can climb very high, and any winning cluster that crosses active Hot Zones receives the combined multiplier value from those cells. 

Hot Zone Strike 

Hot Zone Strike can activate randomly and place 2x multipliers on selected positions. If a chosen position already has a multiplier, the value doubles instead. 

The feature can give a round immediate momentum before clusters begin developing naturally. One well placed Strike can make an otherwise ordinary area of the grid much more useful. 

Collector 

The Collector appears as a moving energy orb and gathers multiplier values from marked positions. The collected total is then added to the Collector itself. 

Persistence can make this effect more important. When a Collector remains active between avalanches, it can repeat its action after each new drop, building from the same round rather than disappearing immediately. 

Dealer 

The Dealer works by targeting positions in a V shaped direction. The direction may face left, right, upward or downward, and affected cells have their values multiplied. 

Like the Collector, the Dealer can stay present between avalanches. This gives the feature a chance to influence several drops within one round. 

Wild Symbols 

The regular Wild substitutes for paying symbols, while the two special Wilds change the grid more directly. The Exploding Wild clears an X shaped area, creating space for new symbols to fall. 

The X Bomber Wild changes symbols in an X shape into a matching fruit or Wilds. That can connect scattered symbols into a larger cluster and interact with existing Hot Zones. 

Bonus Game 

Three Bonus symbols remaining on the grid at the end of a base game round trigger the Bonus Game. During the feature, Hot Zone multipliers stay in place between spins rather than resetting after each round. 

That persistence gives the Bonus Game its main purpose. Position values can continue developing over multiple spins, and Collector or Dealer effects can interact with the growing grid. 

Super Bonus Game 

The Super Bonus Game needs three Bonus symbols and one persistent multiplier feature, either Collector or Dealer, active at the same time. The enhanced round keeps that persistent feature present throughout. 

Rules otherwise follow the Bonus Game structure, with Hot Zone multipliers carried between spins. Starting with Collector or Dealer activity gives the round a stronger opening than the standard version. 

Boomberries uses a fixed 6x7 grid with cluster pays. A potential win requires at least five matching symbols connected horizontally or vertically. Diagonal contact doesn’t count, so fruit needs to form a proper joined group rather than wave at each other from the corners. 

After a cluster pays, symbols fall through the grid and new ones appear from above. Larger clusters pay more than smaller ones, while Hot Zone multipliers can change the value of future wins that pass through marked cells. 

There are no regular paylines or Megaways reels here. Position matters just as much as symbol type, because repeated activity in the same spaces can raise multiplier values. The grid therefore becomes more interesting once avalanches begin, especially when Big Symbols, special Wilds, Collector and Dealer effects start pushing the round in different directions. 

Cluster wins, fruit symbols and position multipliers also appear in these related titles across online casinos. 

• Oxygen: This is the closest comparison, since ELK Studios uses the same broad structure with Hot Zones, Collector and Dealer effects in an underwater theme. 
• Sweet Bonanza 2500: Fruit symbols, tumbling wins and multiplier potential create another colourful game where one round can change through repeated drops. 
• Candy Crazed Pandas DoubleMax: This title keeps the fruit focus and energetic presentation, though it uses a different feature flow from Boomberries. 

The mechanics carry Boomberries much further than the theme does. Hot Zones, persistent multipliers, Big Symbols and special Wilds give the grid plenty to manage, and the Bonus Game makes good use of position values that survive between spins. 

The weaker side is the sense of déjà vu. Anyone familiar with Oxygen will notice the close relationship quickly, and the cheerful fruit village doesn’t fully disguise how similar the structure feels. It’s bright, tidy and easy to read, but not especially surprising. 

Our verdict lands somewhere in the middle. Boomberries has a solid ELK style engine underneath the fruit paintwork, yet the theme doesn’t add enough personality to make the familiar mechanics feel newly picked.
