Big Bang Boom Features

As you can probably tell from the camp Blade Runner aesthetic, this is not your average slot. It has a 4x4 game area, or does it? In order to win, all you need are 3 of the same paying symbols to land anywhere on adjacent reels—beginning from the leftmost reel. The symbols in ascending order are J, K, Q, A, Smiley Face, Butterfly, Heart and Spray-paint Crown. 3 of kind wins you anywhere between 0.12x to 0.4x your stake, and 4 of the same will bag you between 0.20x and 1x. 

Super Bombs, Expanding Reels and Cascades

Once they’ve landed, winning combinations explode, thereby expanding the reel by removing vertically adjacent bricks. In the base game, Super Bombs explode to remove vertically adjacent bricks, too. The game area can increase to 4x10! Any spaces left by bombs and exploding symbols are filled by a new symbols. These continue until there are no new win combos nor any bombs. That’s when the grid returns to its default size of 4x4.

There are 7 different types of bomb. The Vertical, Horizontal and Diagonal Bombs explode vertically, horizontally and diagonally, respectively, removing any adjacent symbols or bricks. Plus-Pattern Bombs work the same as the Diagonal but rotated 90 degrees. Omni-directional Bombs blow up adjacent symbols or bricks in every direction. The Cluster Bomb blows up 3 to 5 random positions

The Persistent Bomb, however, only shows up in the Free Spins game. It blows up all adjacent symbols but maintains its position and keeps exploding on each subsequent spin.

Some players outside of the UK can buy 6 free spins for 75x and they can also buy 6 free spins with a Persistent Bomb on the reels for 150x.

Free Spins

If the grid ends up expanding to 10 rows in height, 6 free spins are awarded. During these Free Spins rounds, the grid can further expand to 8x10. Instead of the normal pay symbols, the only symbols that fall are bombs and 1x Prizes, but when a bomb blows up a Prize symbol, said Prize’s value is increased by x1. You can potentially end up with a maximum multiplier of 2,048x!

Treasure Prizes

Treasure Prizes are sometimes found when new positions are uncovered. In the base game, they consist of Bombs, but during Free Spins you can also find Prize symbols of 16x, 32x, and 64x, not to mention an Additional Free Spin Bomb.

Big Bang Boom Review

Eighties and early Nineties-throwback cyberpunks, come on down! If you’re looking for something a little different, both with respect to gameplay and aesthetics, NetEnt’s Big Bang Boom might be for you. No standard paylines here. This 4x4 grid expands both its dimensions and your win potential, offering between 256 and 10,000 win ways. Even a hardcore cyber-anarchist wouldn’t spit at the max win of 4,300x

Design

The neon lighting might remind Hacksaw Gaming fans of Chaos Crew, although the graphics here are a bit more defined. Another cool visual aspect is how the screen zooms out as bricks are blown away, increasing the dimensions of the game area in the process. When it comes to the cascades of symbols, however, things can get a little bit dull—you’ll think you’re back in a 90s arcade. Then again, I imagine that’s the point. 

Players can hear in the distance what sounds like a New Order/The Cure instrumental concert, which most will appreciate, especially if they were born before 1999. The sound of the bombs and bricks exploding is really satisfying, too.

Game Play

The Expanding Reels feature is a nice change of pace compared to the endless flow of fixed-reel games. When you enter the Free Spins round, there’s a lot going on to keep you fully engaged. Unsurprising, given that the grid can expand to 8x10 in dimension

Win Potential

You could argue that the max win of 4,300x is a little underwhelming, but you can bet up to £100 per spin if you wish. As any cyberpunk would tell you, one has to speculate to accumulate. There’s also a decent default RTP of 96.07%, not to mention the potential 10,000 win ways.

Our Verdict

You’d be hard-pressed to find something negative to say about this Big Bang Boom—it’s simple enough to play while offering interesting features and a host of ways to win big. Impressive in all areas without being particularly exceptional in any.
