Big Bang Boom Online Slot Review

Bright graffiti and colorful bombs share the reels of the Big Bang Boom online slot from NetEnt. Play starts on a 4x4 symbol grid that can expand up or down to a maximum of 10x4 over any series of wins, or via explosions. Different bombs expand the reels in different ways or remove symbols to trigger cascades of those above.

Reach the maximum grid size to trigger free spins, where reels can expand even further to a huge 10x8. Only multiplier symbols or bombs feature in the free games round, where you can uncover Treasure Prize symbols worth up to 64x the stake. Bombs build multipliers even further and it’s here that wins can hit a maximum of 4,300x the total wager.

Big Bang Boom is a highly volatile slot with average returns of 96.07%. You can enjoy the explosive gameplay and features on PCs, iOS, Android, or Windows mobiles at the best Pennsylvania slots sites and New Jersey slots sites.

How to Play the Big Bang Boom Slot

Bright pink and blue lights shine on a graffiti-covered brick wall behind the 4x4 symbol grid. The vivid color scheme extends to the neon spray painted symbols such as a smiley face, butterfly, crown, and high card emblems. Look out for the various colorful bomb modifiers that remove symbols or expand the grid. 

Tap the Bet indicator and pick from a range of 0.25 to 100.00 per spin at any of the top Betting Sites. A Buy feature is available and this triggers the free games for 75x the stake, or 150x with a persistent bomb active throughout. The rev counter and circular arrows on the control panel unlock quick spin and automatic spin options respectively.

The gameplay is quite unusual, so be sure to read the paytable before you play the Big Bang Boom online slot with real money. It’s under the ‘I’ button at the top of the game and has details on symbol values. You win with matched symbol on adjacent reels from the left on any rows, with the most valuable paying up to 1x the stake. 

Free Spins & Other Big Bang Boom Slot Features

Any win triggers Avalanches, as the winning symbols vanish and those above drop down. New symbols fall in from above the reels and Avalanches repeat for as long as they form further wins. 

In the base games, the reels expand upwards or downwards from the base 4x4 to a maximum of 10x4. This happens when winning symbols are adjacent to the brick blocker tiles or when bomb symbols land on the reels and explode next to blockers. 

Here how the different bombs remove adjacent blockers and symbols to expand reels and trigger Avalanches –

Vertical Bomb – Removes symbols above and below itself.

Horizontal Bomb – Removes symbols to the left and right of itself.

Diagonal Bomb – Removes symbols in the corner positions to itself.

Plus-Pattern Bomb – Removes symbols to the top, bottom, left, and right of itself.

Omni-Directional Bomb – Removes all adjacent symbols. 

Cluster Bomb – Uncovers 3, 4, or 5 random positions.

Everything resets on non-winning spins. If the reels hit the maximum of 10 rows high, you get 6 free spins that start out on the full 10x4 grid, and only bombs, 1x multiplier symbols, or blanks feature in this round. Any 1x symbols remain locked in place, doubling in value each time they are affected by bombs. You’ll also find a new Persistent Bomb that explodes all adjacent symbols on every remaining free game.

The reels can now expand horizontally as well as vertically, to a maximum of 10x8, giving you more symbol positions to fill with multipliers and bombs. 

Treasure Prizes can be found under blockers in the base games and during the free spins. In the base games, they consist of new bombs. In the free spins you can get bombs or multipliers of up to 64x the stake, and during the bonus round uncovering a Treasure Prize adds one extra free spin to the total.

Our Big Bang Boom Slot Rating

The neon graphics add lots of color to the Big Bang Boom slot machine while a punk soundtrack adds to the counter-culture style. You can enjoy plenty of innovative features here, with expanding reels giving you more ways to win over any series of Avalanches, and a fantastic free spins feature with the potential to unlock a vast 10x8 grid. Increasing multipliers and the Treasure Chest prizes can add up as the free games unfold, potentially leading to a big payout at the end.

There’s no wild symbol to help, but this aside, the Big Bang Boom online slot is a great addition to the NetEnt range. Check it out along with their other games at the best New Jersey casinos and top Pennsylvania casinos.
