    The Big Bang Boom Slot Game

    Graphically, this NetEnt slot has an up-close resemblance with the Chaos Crew sequel from Hacksaw Gaming.

    As a side note, take a moment while reading this review to also practise the gameplay using the Big Bang Boom demo. It’s available at free of charge!

    Now, back to the game. It uses neon-esque graffiti that delivers a funky atmosphere. As the reels expand, they’ll reveal colorful yet good-quality symbols. Here, the vibe is enhanced by the ambient sounds of a city’s night scene, including sirens coupled with an electric soundtrack.           

    Once you enter the gameboard, you’ll notice the controls below the reels and in the top-right corner. Nonetheless, they are in clear view for a seamless experience when playing the Big Bang Boom slot game reels.

    Symbols and Payouts

    The Big Bang Boom online slot game dons 8 regular symbols and 7 types of Bombs. Apart from the screen’s design, the slot also incorporates thematic symbols in its lineup.

    The paytable displays all the payout rules besides the symbol combinations and potential wins. So, ensure you go through it to be in the loop about what to expect to trigger payouts.

    To save you from looking far for the table, you can still use the Big Bang Boom free demo from! For the record, the website won’t prompt you for any payments!

    Payouts are based on the selected stake!

    The minor symbols are the Ace to Jack royals. The J & K give out 0.08x and 0.16x for 3-plus of each, while the Q and A pay 0.12x and 0.2x the total stake. Then, the high-winning Blue Smiley Face and Green Butterfly award 0.2x and 0.4x, while the Heart and Crown pay up to 0.6x and 1x the current bet, respectively!  

    A unique aspect of this game is that it has no wilds or scatters. However, you’ll notice that it incorporates a set of Bombs, which can trigger extra features. Find out how in the following Big Bang Boom slot review segment!

    Big Bang Boom Slot Bonus Features

    This game has enough features for everybody, ranging from expanding reels to free spins!

    Expanding Reels

    Every main game starts with 4 reels and 4 rows, but the rows can expand to 10. Further during the Big Bang Boom bonus spins, the grid can grow to 8 columns and 10 rows!

    A new position is revealed when an icon vertically adjacent to it participates in a win or when a bomb explodes, directly affecting a covered cell.

    Super Bombs

    The Vertical, Horizontal, Diagonal, and Plus-pattern Bombs land in the base and free games, while the Persistent Bombs hit in the bonus spins only.

    However, Cluster Bombs and Omni-directional land in the Treasure Prize feature, main game, and free rounds!

    • Vertical, Horizontal, Diagonal, and Plus-pattern Bombs pop and remove icons adjacent to their respective positions.
    • Omni-directional - explodes alongside all icons connected to it.
    • Cluster - randomly uncovers 3-5 covered positions in the main game. However, in the free spins, it unveils 3 to 5 random positions unoccupied by other bombs.
    • Persistent - detonates alongside all other connecting icons, persisting on the reels to explode again.

    Big Bang Boom Free Spins

    Growing the reel area to 10 rows in the main gameplay triggers 6 free rounds. All the Bombs except the Omni-directional and Cluster Bombs and doubled Prize values worth 1x to 2048x appear in the bonus.

    The appearing Prize values persist on the reels for the entire bonus.

    Treasure Prize Feature

    Can be discovered when a new position is unveiled on the reels. In the base game, all the Bombs, barring the Persistent Bomb, are Treasure prizes.

    However, the following prizes are available during the Big Bang Boom free play:

    • Large prizes worth 16x to 64x the stake, in multiplies of x2!
    • +1 additional free spin.

    Buy Feature

    Although not available in all jurisdictions, players who can access this feature can use it to immediately enter the free rounds! The feature costs 75x or 150x bet depending on the choice picked.

    How to Win at Big Bang Boom Slot

    The Big Bang Boom online slot has a default 4 by 4 grid. However, it can grow to 10 rows in the base gameplay and 8 by 10 during the free spins. Resultantly, the game plays from 256 up to 10,000 win ways!

    Matching symbols in 3+ adjacent reels, beginning from the leftmost column to the right, will trigger a win. The winning symbols cascade, allowing for potential multiple payouts per spin.

    Before you start playing, use the bet modifiers to adjust the stake values. Here, it’s possible to wager from €0.25 to €125 for every round.

    The Spin button is your gateway to spinning the reels. To its right is the Autoplay feature, which you can use to set up auto-spins. Meanwhile, the Turbo mode, which speeds up the reels, is on its left-hand side.

    On the top-right corner of the Big Bang Boom slot, you’ll find other optional buttons, which open the paytable, settings, and help pages.

    Big Bang Boom Slot RTP & Volatility

    According to NetEnt’s website, this slot’s volatility is high. The expected Big Bang Boom RTP is 96.07% during regular games. However, based on the buy feature selected, it reduces to 96% or 96.05%.          

    The Final Thoughts

    The use of an explosive theme isn’t common in the iGaming space. Although well done in thisNetEnt production, the appeal for detonations can vary from one individual to another.

    Nonetheless, should you anticipate a bombastic experience in this slot?

    Coming from a bonuses point of view, yes! You should expect some explosive action from the expanding reels and avalanches. The occurrence of Bombs triggers explosions for more avalanches. Not to forget, you also get free spins with up to 2048x prizes, a Treasure Prize feature, and a bonus buy option!

    Unfortunately, the slot is somewhat ideal for high-risk players owing to its high bet limits. So, if you’re a low roller, you could probably find the Chaos Crew Scratch slot more ideal.

    I hope that after reading this Big Bang Boom slot review, you are more confident to gamble. The GoodLuckMate website has listed reputable online casinos worth playing from!
