Boombear Bros

Boombear Bros is a cartoon cluster slot made by Bullshark Games and offered on the Hacksaw platform, released in September 2026. Two bear brothers, one in red with a flame and one in white with a block of ice, stand in front of rival fortresses on a battlefield of snow and flowers, and the whole game is about bombs: bombs that multiply, bombs that spread new symbols, and bombs that explode in four directions. The grid is 6x6, the wins are cluster pays, the RTP is 96.32%, the volatility is medium and the top prize is 12,000x the bet.

Clusters And Cascades

There are no paylines. A win needs a group of five or more matching symbols that touch each other horizontally or vertically. The winning symbols explode, the remaining ones fall and new ones drop in from above, and the sequence goes on until no new cluster appears. The hit frequency is about 27%, so more than one spin in four pays something, which keeps the base game lively. Bets range from 0.10 to 75.

The Cast Of Symbols

The four low symbols are the card suits in stone-like tiles: diamond, club, heart and spade, and a cluster of 27 or more pays 10x the bet. The high symbols are battle gear: a blue shield, green armour, yellow goggles, a purple hammer and a white bear, with the largest clusters worth 30x to 60x. The brown bear is the Wild, which replaces every paytable symbol, and a full cluster of 27 Wilds pays 100x on its own. The red-marked Scatter is a bomb crate.

Fire And Ice Power Bombs

The two Power Bombs are the core of the game, and each one lands with a random direction (horizontal, vertical or both) and a random length of one to five cells.

• The Fire Power Bomb adds a cell multiplier from 2x to 20x to every cell in its blast area. If two bombs hit the same cell, their values are added together, and a winning cluster collects the multipliers of all its cells.
• The Ice Power Bomb adds matching symbols inside its blast area after the grid settles, and the added symbol can be any paytable symbol or even a Wild. This helps to build bigger clusters on the following cascade.

In the base game the cell multipliers build during the cascades of one spin and disappear when the spin ends, so a long chain with several fire bombs is the way to a large win. On a spin without any win or bomb, the Bomb Frenzy mystery event can add between two and five bombs to the grid.

How A Big Spin Builds Up

The best way to understand the game is to follow one chain. A cluster pays and explodes, new symbols fall, and a Fire Power Bomb lands somewhere in the middle of the grid. Its blast paints a row or a cross of cells with multipliers, and the next cluster that includes those cells is paid with all their values added together. If an Ice Power Bomb then fills the area with matching symbols, the next cluster can be much larger than anything the random drop could have made.

A Battlefield That Changes Colour

The two fortresses behind the grid are drawn in warm red on the left and cold blue on the right, and the bear brothers cheer on the bottom left of the screen. When a bonus round starts, the background shifts to a darker, glowing red and blue scene and the title card of the round appears with the Bullshark Games logo, which makes the switch from the base game very clear.

Two Free Spins Rounds

Scatters decide which bonus you get:

• Bombs Away: three Scatters award 10 free spins with progressive cell multipliers, which means the multipliers stay on the cells from spin to spin;
• Maximum Blast: four Scatters award 12 free spins, with progressive multipliers and Power Bombs that explode in four directions at once.

Each additional Scatter adds one more spin. During the bonus the board fills with cell multipliers such as 4x, and the cascades of a purchased Maximum Blast round showed payouts like 20.00, 20.60 and 24.00 on a 2.00 stake within the first few spins.

Buying The Action

The Buy Bonus button opens four options. At a 2.00 bet the prices are:

• BonusHunt FeatureSpins, 6.00 (3x): each spin is five times more likely to trigger a bonus;
• Short Fuse FeatureSpins, 100.00 (50x): at least two Power Bombs land on every spin, and the bonus Scatter cannot appear;
• Bombs Away, 200.00 (100x): ten free spins start at once;
• Maximum Blast, 500.00 (250x): twelve free spins with four-direction explosions.

A confirmation window shows the price before the balance is charged, and the FeatureSpins versions stay active until you turn them off.

Which Buy Option Fits Which Player

BonusHunt is the gentle choice: the base game continues as normal, but the bonus arrives five times more often. Short Fuse is the choice for players who enjoy watching the bombs work, because two Power Bombs land on every spin while the bonus Scatters stay away. Bombs Away and Maximum Blast are the direct routes Maximum Blast adds two more spins and the four-direction explosions.

RTP, Volatility And Max Win

The main RTP is 96.32%, and the game can run at lower settings down to 94.36% at some casinos, so check the rules in the game. The volatility is medium, and the maximum win is 12,000x the bet.

Who Will Enjoy The Bears

Boombear Bros fits players who like colourful, easy-to-read cluster slots with a lot happening on the screen. The two kinds of bombs give each spin a small story, and the choice between four buy options lets you pick how much risk to take. Because the multipliers disappear after every base-game spin, the biggest chances sit in the bonus rounds, so it is best for players who are patient enough to wait for the Scatters or happy to pay for them.
