NetEnt is a studio that has a history of making a bang in the iGaming industry, and they have set out to do that once again, quite literally this time, with the Big Bang Boom online slot. As its name might suggest, this is not a game that is about subtlety. The aim of Big Bang Boom is to land as many consecutive wins as you can to unlock the game grid and the potential prizes on offer. Is the game as explosive and exciting as it sounds, though? In this Big Bang Boom slot review, we will take it for a spin and find out. 

When you first load up Big Bang Boom, you could be forgiven for wondering whether Hacksaw Gaming actually developed this slot. The slot uses a graffiti-esque art style, which we have seen in titles like Break Bones and Chaos Crew. It provides the slot with a really anarchic and fun edge, and it feels like a new direction for NetEnt. The game’s reels are styled to look like a brick wall, with the wall expanding and bricks exploding as you land winning combinations. It’s an excellent design that really helps the game to stand out. 

It is all complemented by a fast-paced, modern urban soundtrack that helps give the game a really lively atmosphere. Some really neat, glitch-style animations help you transition between game modes. 

The whacky design of Big Bang Boom lends itself really nicely to mobile play. The lack of visual clutter means it is perfect for the small screen, and NetEnt has done an excellent job of optimizing it for both Android and iOS, as well as top casino apps. 

The base game of Big Bang Boom provides some of its most chaotic and enjoyable moments. The slot uses a 4x4 grid to start, with 256 active ways to win. Whenever players land a win, they might unlock a new part of the grid, with positions being unlocked if an adjacent win is formed. This can also be achieved by landing a bomb on the grid. 

In the base game, the grid can only expand vertically, with the ability to unlock positions horizontally only available in the free spins round, which we will get to later in this Big Bang Boom slot review. All in all, it is possible to unlock up to 10,000 ways to win in the game. 

The stake for the game is adjusted using the +/- buttons under the reels. The minimum bet in the game is $0.25, and the maximum is $100, giving players plenty of flexibility. 

As we have mentioned already, a lot of the fun in this game comes from unlocking the positions on the reels and helping to expand the number of winning ways. The slot uses an Avalanche mechanic to make this possible, with winning symbols disappearing and being replaced by new ones. When no new wins are formed, the grid will reset back to its original size, and the Avalanche sequence will end.

Bombs are also essential to success in the game, and there are seven types you will need to get acquainted with. Three of these, the Vertical, Horizontal, and Diagonal, all indicate the direction the bomb will explode to remove symbols. 

The Plus-Pattern Bomb and the Omni-Directional Bomb explode in a cross-shape and destroy adjacent symbols, respectively. The Cluster Bomb removes three to five random positions, while the Persistent Bomb only appears in Free Spins, explodes adjacent symbols, and remains in place for the duration of the round. 

Speaking of the Big Bang Boom free spins, the bonus is rewarded when the grid reaches ten positions high. Players get ten spins, and the grid is expanded to 4x10 for the round. It is possible to expand the grid outwards to an 8x10 size. Standard symbols are removed, with the bonus using prize symbols that stick to the reels and the aforementioned bombs. At the end of the round, all prizes are calculated and paid out. 

Depending on your location, you can also buy your way into the bonus for the cost of 75x your original stake. 

The Big Bang Boom slot serves up a maximum win of 4,300x your stake. This might not be as explosive and exciting as other areas of the game, but it is still a solid number. The RTP is 96.70%, which is slightly higher than the industry average. It is worth noting that several other versions of the game exist with lower RTPs, so be sure to check before you hit spin. Finally, the game has been given a high volatility rating by NetEnt. 

Big Bang Boom feels fresh and different from other NetEnt slots, and it also boasts some excellent gameplay. The design is really fun, and the gameplay features, especially the use of the bombs, can lead to some really chaotic and highly enjoyable sequences. This is the type of slot where you can land one win and then just watch the carnage unfold on the reels as a result of it. The maximum win is perhaps not as big as the highly volatile and chaotic gameplay style might have suggested, but there is still plenty to enjoy here. Overall, this is a unique and anarchic slot game that we are more than happy to recommend taking for a spin at your favorite top online casinos.
