Boombear Bros

Boombear Bros follows the antics of two mischievous bear siblings with a near-worshipping love of demolition. Harnessing fire and ice, they constantly craft new ways to raze each other’s fortress. Sometimes they work together, other times they’re at each other’s throats. The realm splits neatly: the left blooms with flowers and green grass, the right embraces snowy winter, each guarded by identical fortresses. Cartoonish visuals and a whimsical soundtrack give their clash a merry touch. Both bears stand together, a playful enigma. Amid this lighthearted chaos, a single spin can reward you with up to 12,000x your bet.

Boombear Bros Gameplay and Mechanics

Boombear Bros is a 6×6 cluster-pays slot from Bullshark Games where wins are formed by landing 5 or more matching symbols orthogonally adjacent. After each win, the winning symbols explode, allowing new symbols to cascade onto the grid for chain reactions. Wilds appear as a brown bear, substituting for all regular symbols and paying 100x the bet for independent clusters of 27 or more wilds. The Free Spins scatter is a crate of bombs. The explosive line-up includes Cell Multipliers that boost wins, Power Bombs blasting symbols in patterns, the Bomb Frenzy modifier, and two bonus rounds – Bombs Away Bonus and Maximum Blast Bonus. Landing enough FS Scatters triggers these features, while the Feature Buy option provides direct entry for a set cost.

Boombear Bros Theme and Visuals

Boombear Bros showcases two mischievous bear siblings whose near-worshipping love of demolition plays out in a cartoon world neatly split between fire and ice. Flowers and green grass bloom on the left, while the right side glistens with snow, each guarded by identical stone-and-wood fortresses bristling with cannons and watchtowers. The brothers harness opposite elements to raze each other’s strongholds, but surprisingly, they stand together as a team, keeping the rivalry playfully ambiguous. Bouncy animations, a whimsical soundtrack, and lighthearted visuals soften every explosion, turning their destructive antics into a merry, almost festive sibling squabble where chaos never feels mean-spirited.

Boombear Bros Slot Features

Chaotic explosive cluster wins, cascading reels, wild bears, cell multipliers, and truly fiery bomb-powered bonuses turn every spin into a spectacle. Let’s look at the features that make the game potentially rewarding for all players.

Cell Multipliers

The default value is none. Cell multipliers are increased only by the Fire Power Bomb symbols. The Cell multiplier is applied to any win that includes a symbol from that cell. If a winning combination includes symbols on multiple cells with multipliers, their values are added together and then applied to the win. Cell multipliers are progressive during all cascades, but reset at the start of each new spin. Note: Cell multipliers from the triggering spin do not carry over to the bonus game.

Power Bomb Symbols

Can land during the base game and bonus games or be added by the Bomb Frenzy mystery event. Power Bomb symbols always have a random direction and length that determines the impact of its explosion. Possible explosion directions: Horizontal (travels left and right), Vertical (travels up and down), and Cross (travels in all four directions). Possible explosion lengths: 1, 2, 3, 4, 5. The reach of an explosion is limited by the edge of the 6×6 grid.

Fire Power Bomb

When it lands, it adds multipliers to all the cells within the explosion’s reach, including the cell where the symbol originally landed. Multipliers are added to the cells immediately following a spin or cascade, ensuring they are active for the subsequent win calculation. Possible multiplier values: 2x, 3x, 4x, 5x, 6x, 7x, 8x, 9x, 10x, 15x, 20x. Every cell affected by a single bomb will receive the multiplier value. There can be several Fire Power Bomb symbols on the grid at the same time, and the order of action is from left to right, top to bottom. Each bomb will have its own multiplier value. If several bombs add multipliers to the same cell, their values are added together. The symbol itself transforms into a random paying symbol or a Wild symbol.

Ice Power Bomb

When it lands, it adds matching symbols to the grid within the explosion’s reach. Activates only after the grid is settled and no more wins are present. All symbols in the paytable can be added, including a Wild symbol. Other bombs, existing Wild symbols, or FS Scatter symbols will not be overwritten, and those cells remain unchanged. There can be several Ice Power Bomb symbols on the grid at the same time, and the order of action is from left to right, top to bottom. All bombs add the same symbol type, though the decision to add a Wild symbol is determined independently for each bomb. The symbol itself transforms into the same symbol that was added.

Bomb Frenzy

In any random spin where there are no wins and no Power Bomb symbols on the grid, a Bomb Frenzy mystery event may trigger. When the event triggers, a random number of bombs (2, 3, 4, or 5) are added to the grid. Both types of Power Bomb symbols can be added. Bombs added will not land on top of Wild symbols, other Bomb symbols, or FS Scatter symbols.

Wild Symbol

Can land during the base game and bonus games or be added by the Ice Power Bomb symbol. Substitutes for all symbols in the paytable.

Bombs Away (Bonus Game)

3 FS Scatter symbols start the bonus game with 10 free spins. This bonus keeps the base game’s mechanics, with the difference that cell multipliers are progressive.

Maximum Blast (Bonus Game)

4 FS Scatter symbols start the bonus game with 12 free spins. This bonus keeps the base game’s mechanics with the differences that cell multipliers are progressive and all Power Bomb symbols explode in four directions. Each FS Scatter symbol during the bonus game adds +1 free spin.
