How To Play Big Bang Boom Mobile Slot

The NetEnt Big Bang Boom slot gives a 4×4 256 ways to win game that increases up to 10 rows high or 10,000 ways to win. It certainly brings the bang, with will it boom your wallet?

The Big Bang Boom mobile slot is an expanding reel game where every win explodes the touching stone area around it. You can find up to 8 bombs in the base game and 9 in the free spins, all aimed at opening up the game and providing bigger wins.

In the base game, you get that via the paying symbol. In the free spins, you get 1x sticky multipliers that double each time a bomb explodes. Big Bang Boom is one of the higher volatility NetEnt slots with a high RTP of 96.7% and a decent win of 4,300x your bet.

However, it’s an unusual game in that the paytable doesn’t pay out much, but if you can get to the free spins, you’ll see yourself close to that top win. But even then, you’ll need to unlock the full 8 reels and 10 rows of sticky wins and bombs to get anywhere close – it’s not an easy feat.

How the bombs and the expanding reels work

When a symbol is adjacent to a wall and is part of the win, the wall piece opens up, and more paying symbols drop down to replace the winning symbols. You also get direction bombs that destroy either symbols or wall pieces nearby.,

The Big Bang Boom slot has avalanching wins, but only in the sense that the expanding reels open up space to fill up.

The Bombs are the big draw – the more you get, the more you’ll win. But you won’t win much, certainly nothing to shout about.

However, the aim of the slot isn’t to get wins in the base game. It’s to open up the 4 reels to be 10 rows high. Because then you’ll have 6 free spins filled with wins.

The Big Bang Boom slot free spin

You have 4×10 reels, but only 1x multipliers and bombs will land. The bombs will double the multipliers. You can double the multipliers so each one can have a maximum of 2048x.

But wait, didn’t you say the max win of this Big Bang Boom game is only 4,300x your bet? Yeap. I also said that you only get 6 spins.

If you double a 1x multiplier, it only gives you 64x wins in 6 spins and 6 bombs in a row. But as you open up the walls, you can catch bigger multipliers – starting at 64x and even more free spins. It’s not likely you’ll get one to 2048x, never mind more than one, is what we are saying.

Does the Cash Truck slot or the Money Train 4 review do it better? Absolutely. But this is still a fun enough variation of the game that fans of NetEntertainment will certainly have plenty to play for.

Big Bang Boom Bonus Features

Win Ways Pay: Symbols Pay left to right on reels 1 to 4. The number of winning bets is calculated by multiplying the number of symbols on each of the reels. So 3x2x1x2 = 12 win ways. The 256 bet ways may increase to 10,000

Expanding Reels Feature: You start with a 4x4 reel area. You can expand the area in one of two ways:

  1. When a symbol that is vertically adjacent becomes part of a win.
  2. When a bomb explodes and directly affects a covered position.

In the base game, the reel expands to 4 reels and 10 rows high. In the free spins, the reels can expand to 8 reels and 10 rows high.

Super Bomb Feature: These bombs expand the reels in different ways.

  • Vertical Bomb: Explodes in a vertical direction.
  • Horizontal Bomb: Explodes in a horizontal direction.
  • Diagonal Bomb: Explodes in a diagonal direction.
  • Plus-Pattern Bomb: Explodes in a cross-shaped direction.
  • Omni-Direction Bomb: Explodes along with all symbols adjacent to it's position
  • Cluster Bomb: In the main game, it randomly uncovered 3-5 covered positions. In Free Spins, it explodes 3 to 5 random positions that are not occupied by any other bomb.
  • Persistent Bomb: Only appears in free spins. Explodes along with all symbols adjacent to its position and stays sticky on reels, exploding each free spin.

Free Spins: Expanding the play area to 10 rows high activates 6 free spins. During the free spins, only prizes with a 1x will land on the reels. These prizes stay sticky on the screen, and bombs can increase the prize on the screen. You can also increase the reels to 8 reels and 10 rows high.

The Multipliers will double each time a bomb makes it explode from 1x, 2x, 4x, 8x, 16x, 32x, 64x, 128x, 256x, 512x, 1024x, to 2048x.

At the end of the free spins, you win the total of all the prizes on the screen.

Free Spin Treasure Prize Feature: When you uncover new positions on the reels, they can uncover prizes. These include:

  • Larger Prize starting at 16x, 32x, 64x
  • Extra Free Spins: +1 free spin

Buy Bonus: You can buy entry into the bonus at any time.

  • 75x your bet: 6 free spins
  • 150x your bet: 6 free spins with one persistent bomb randomly on the reels

Pros

  • High 96.7% RTP
  • Free spins with Expanding Reels and bomb multipliers
  • Super Bomb feature adds more action & entertainment

Cons

  • Low top win for a high variance slot

Big Bang Boom Review Conclusion

The Big Bang Boom slot on mobile by NetEnt looks beautiful, but a few core issues make it short of great. Primarily, the fact that the top win is only 4,300 your bet, and getting there is hard work, even with those fun free spin mechanics.

Thankfully, you have a wide betting range of 0.25 to 100 a spin, allowing you to judge how much you want to bet. This is a very volatile game but one with one great feature that can explode your wins.

Watching those reels expand in the base game, and the free spins is always fun, and a slot theme that keeps you spinning.

A fun little game to play at NetEnt casinos if you're a fan of the casino game provider.

Expert Rating: 3 / 5
A solid slot with good wins and reliable mechanics. It may not break new ground, but it's worth a spin
