Big Bang Boom Slot Review

The Big Bang Boom slot from NetEnt is a graffiti-inspired game packed with colourful symbols and explosive modifiers. It starts on a 4x4 grid that can expand vertically to 10x4 as wins trigger cascades. Different bomb types remove blockers or symbols, allowing the reels to grow and Avalanches to continue.

Reach the full 10x4 grid to unlock free spins, where the reels can expand even further to a massive 10x8 layout. Only bombs, multipliers, and Treasure Prize symbols appear in the bonus, with potential rewards up to 64x the stake. Combined with multiplier-building bombs, payouts can reach up to 4,300x your bet.

This high volatility slot has an RTP of 96.07% and can be enjoyed on desktop, iOS, Android, or Windows devices at the best Big Bang Boom slot sites.

How to Play Big Bang Boom

The game is set against a neon-lit, graffiti-covered wall with spray-painted symbols such as crowns, butterflies, and card emblems. Bombs are central to gameplay, with each type offering unique effects that clear symbols or expand the reels.

Bets range from 0.25 to 100.00 per spin. A Buy Feature (outside the UK) allows instant access to the free spins for 75x the stake, or 150x with a persistent bomb active. Quick Spin and Autoplay options are available where permitted.

Wins are achieved by landing matching symbols on adjacent reels starting from the left, regardless of row. The paytable, accessible via the information button, explains symbol values and mechanics, with top symbols paying up to 1x the stake.

Big Bang Boom Free Spins and Bonus Features

Every win triggers an Avalanche, with symbols removed and new ones falling from above. In the base game, reels expand to a maximum of 10 rows high whenever wins or bombs remove blockers. If the reels reach 10x4, the free spins feature activates.

Bomb types include:

• Vertical Bomb: Removes symbols above and below.
• Horizontal Bomb: Removes symbols to the left and right.
• Diagonal Bomb: Clears corner positions.
• Plus-Pattern Bomb: Clears symbols in a cross pattern.
• Omni-Directional Bomb: Removes all adjacent symbols.
• Cluster Bomb: Uncovers 3–5 random positions.

During free spins, reels expand both vertically and horizontally up to 10x8. Multipliers stay in place, doubling when affected by bombs, while Persistent Bombs explode on every spin. Treasure Prizes may also appear, awarding multipliers or bombs, and can add extra free spins to the total.
