Boomberries

BoomBerries is a cluster pays slot developed by ELK Studios, released on June 24, 2026. Set in the fictional Boomberry Valley, the game places fruit symbols and volatile bomb characters side by side on a 6-column, 7-row grid. The core mechanic revolves around cluster pays combined with a layered multiplier system, including Hot Zones, a Collector, and a Dealer — features that interact with each other to compound multiplier values across drops.

With a maximum win of 25,000x the bet and high volatility, BoomBerries targets players who prefer mechanics-heavy gameplay with significant swing potential. ELK Studios' proprietary X-iter™ feature is also included, offering five game modes to adjust how you enter the action.

BoomBerries is set in a colourful cartoon world called Boomberry Valley. The background shows a lush, sun-lit landscape with oversized fruit growing from the ground and whimsical mushroom-style houses. Symbols are rendered in a bold, rounded art style — strawberries, pineapples, watermelons, blackberries, and smaller berry types are the main cast, each clearly distinct in size and colour.

Bomb characters appear as animated creatures with expressive faces, reinforcing the dual nature of the theme: sweet fruit meets explosive chaos. Animations trigger cleanly on wins and feature activations, with multiplier tiles lighting up distinctly across the grid. The overall presentation is bright and accessible without being cluttered, and the audio matches the upbeat visual tone without becoming repetitive.

BoomBerries uses a cluster pays system on a 6×7 grid. A cluster is formed when five or more matching symbols connect horizontally or vertically. Wins trigger the Avalanche mechanic — winning symbols are removed, remaining symbols fall, and new symbols drop to fill the grid. This continues until no new clusters form.

• Set your bet using the controls at the bottom of the screen (€0.20–€100)
• Press spin to drop symbols onto the grid
• Clusters of 5+ matching symbols pay out; the Avalanche then runs until no wins remain
• Access the paytable via the info button to review symbol values and feature rules
• Use X-iter™ to select an alternative game mode before spinning if desired

Bonus Buy Option: Yes — via X-iter™ (five modes available)

Hot Zones

Certain positions on the grid carry multiplier values (e.g., ×2, ×4). Every time a winning cluster covers a Hot Zone position, the multiplier on that position doubles. Hot Zone values can stack significantly over a run of consecutive Avalanche drops.

Collector

The Collector gathers all multiplier values currently visible on the grid and applies them. This feature can be persistent, meaning it carries over between drops in certain game states.

Dealer

The Dealer redistributes multiplier values across the grid in a V-shape pattern, effectively spreading and multiplying the active values. Like the Collector, the Dealer can also be persistent.

Hot Zone Strike

At the start of any symbol drop or bonus drop, Hot Zone Strike can activate randomly. It places ×2 multiplier values on a random number of grid positions. If a position already holds a multiplier, that value is multiplied by ×2 instead of replaced.

Wild Symbols

Three wild types are present: Wild Symbol — Substitutes for any payout symbol | X-Bomber Wild — Selects a random payout or wild symbol and replaces all payout symbols in an X-shape around itself | Exploding Wild — Removes all payout symbols in an X-shape area directly above and below its position

Big Symbols

Symbols of size 2×2, 3×3, and 4×4 can appear during any symbol drop. These larger symbols occupy multiple grid positions and contribute to larger cluster formations.

Bonus Game

Three Bonus symbols landing in the same drop trigger the Bonus Game. During the Bonus Game, all multiplier values are persistent between drops — they do not reset between Avalanche sequences. The Bonus Game can be retriggered.

Super Bonus

The Super Bonus is triggered when three Bonus symbols land alongside an active persistent multiplier feature. In this mode, at least one multiplier feature remains persistent throughout the entire bonus, increasing the potential for larger multiplier accumulation.

X-iter™ (Bonus Buy)

X-iter™ gives players five ways to enter the game at different stakes:

Wins are formed by clusters of 5 or more matching symbols connected horizontally or vertically. Payouts scale with cluster size. All values below are expressed as multipliers of the total bet.

High-Pay Symbols:

Low-Pay Symbols:

Special symbols include three wild variants (Wild, X-Bomber Wild, Exploding Wild) and the Bonus symbol, which triggers the Bonus Game on three appearances in the same drop.

BoomBerries pays through cluster formations on a 6×7 grid. A cluster requires at least 5 matching symbols connected horizontally or vertically. Each winning cluster triggers the Avalanche — winning symbols are removed, remaining symbols fall, and new ones drop to fill the spaces. This cycle repeats until no new clusters form.

Multipliers from Hot Zones, the Collector, and the Dealer add to the win value during a sequence. In the base game, multiplier positions can carry over within a single Avalanche chain. In the Bonus Game and Super Bonus, multipliers become persistent across multiple drops, which is where the game's higher win potential is concentrated.

BoomBerries does not currently have direct variants, but it shares mechanical DNA with other ELK Studios cluster titles. Players familiar with ELK's multiplier-driven design — as seen in games like Nitropolis or Cygnus — will recognise the layered approach to feature building. The X-iter™ system also appears across ELK's wider catalogue, making it a familiar entry point for existing ELK players.

BoomBerries is a feature-dense cluster slot from ELK Studios with a clear mechanical identity. The combination of Hot Zones, the Collector, and the Dealer creates a multiplier system that compounds in meaningful ways, particularly during the Bonus Game and Super Bonus.

The 94% RTP and high volatility (7/10) mean variance is significant, and sessions without a bonus can be relatively costly. The X-iter™ modes give players direct access to bonus states, which adds flexibility. BoomBerries suits players who prefer mechanics-driven gameplay over passive reel spinning.
