Boombear Bros Slot Review — Bullshark Games

This review is based on pre-release promotional material provided by Bullshark Games. Details may change before or at launch on 23rd September 2026. A full review will follow once the game is live.

Step into the explosion zone for a booming adventure!

Bullshark Games sends two bear brothers — one brown, one panda — into an explosive cluster battle with Boombear Bros, a 6x6 cluster pays slot where Power Bomb symbols land and detonate in cross patterns, either adding matching symbol clusters to the grid or boosting the Cell multipliers sitting on individual positions. The dual outcome of each explosion — cluster creation or multiplier boosting — gives the mechanic genuine variance in what a Power Bomb delivers depending on the grid state when it lands. Pre-release material shows multiplier values of 6x visible across several positions simultaneously, suggesting the Cell multiplier system can reach meaningful values before combining with cluster wins. At a 12,000x max win and medium volatility of 3 out of 5, the explosive chaos is well-packaged.

Core Gameplay

Boombear Bros runs on a 6x6 cluster pays grid with Wild and Scatter symbols both visible in pre-release material alongside the standard paying symbol set. The central mechanic is the Power Bomb symbol, which when it lands triggers a cross-pattern explosion — clearing positions in a cross shape across the grid. Each explosion resolves as one of two outcomes: it either adds matching symbol clusters to the affected positions, seeding new potential wins into the grid, or it boosts the Cell multipliers on those positions, increasing the multiplier value attached to whatever symbols sit there. The pre-release screenshot shows Cell multipliers of 6x across multiple positions simultaneously, suggesting either rapid multiplier accumulation or that multiple Power Bombs can fire in the same spin and stack their boost effects across overlapping cross patterns. How the game determines which outcome a Power Bomb delivers — cluster addition or multiplier boost — is not yet confirmed.

Bonus Features

Scatter symbols are visible across several positions in the pre-release grid, indicating a scatter-triggered bonus of some kind. Full detail on the bonus structure, trigger conditions, whether Power Bombs appear more frequently or with enhanced effects during the feature, and how Cell multipliers interact with the bonus round will be confirmed at launch.

Feature Access & Buy Options

Bonus buy availability has not been confirmed at this stage. Further detail on access options will be added ahead of or at launch.

Next Steps for This Review

At launch the review will be updated to cover confirmed RTP, the full bonus structure, how the Power Bomb's dual outcome is determined, whether multiple Power Bombs can chain their explosions in a single spin, the maximum Cell multiplier value achievable in practice, and the complete feature buy options. A final score and full gameplay analysis will follow once hands-on time with the game is available.
