About Big Bang Boom

Big Bang Boom is a somewhat strange and unusual NetEnt slot with techno beats, a cool urban vibe and lots of exploding bombs and mystery wins.

If that doesn’t pique your interest, we don’t know what will.

It is no surprise NetEnt has been struggling with its form in the past years, but it seems Big Bang Boom is a big step in the right direction.

Big Bang Boom RTP

Big Bang Boom has been released in three Return to Player configurations: 88.10%, 94.08%, and 96.07%.

Big Bang Boom Gameplay and features

Big Bang Boom is a win all ways slot with expanding reels that is played on a 4 x 4 grid with 256 ways to win that can expand to a 10,000 ways to win grid.

Winning combinations are removed to make way for new symbols to create chain reactions. On top of that, the grid expands by removing blocks that are adjacent to winning symbols or by exploding bombs.

When you manage to clear the whole grid, the bonus game is triggered.

Other features include:

  • High variance.
  • Betting starts at 0.25 and goes up to 100 per spin.
  • Premium symbols pay 0.4 to 1 times the bet for 4OAK.
  • Super Bombs: there are 7 types of bombs that blow up symbols and cause avalanches after wins are evaluated.
  • Treasure Prize Feature: Treasure Prizes can appear when new positions are uncovered in the base game or in free spins. Treasure Prizes can consist of Super Bombs, prizes of 16x, 32x or 64x, or extra free spins.
  • Clearing the grid awards 6 free spins:
    • Multipliers can land and stay persistent on the grid for all free spins.
    • Bomb explosions that reach multipliers will double the multiplier value.
    • Persistent Bombs stay on the grid for each spin and explode every turn.

Big Bang Boom Bonus Buy

If your jurisdiction permits it, you are two Big Bang Boom Bonus Buy (how’s that for alliteration?) options:

  • 6 free spins for 75 times the bet.
  • 6 free spins with a Persistent Bomb for 150 times the bet.

What is the max win on Big Bang Boom?

The max win on Big Bang Boom is 4,300x the bet, which feels too low for such a high variance slot with mechanics that scream massive wins.

CasinoWizard’s verdict: 4 out of 5 stars

Big Bang Boom is a delightful slot that is surprising different to most other NetEnt slots.

The urban vibe reminds us of Chaos Crew and the growing reels have some similarities to the PopWins slots mechanic. Don’t get us wrong, though: Big Bang Boom manages to stand firmly on its own two feet.

It’s great to see NetEnt try something new, with an agressive style and innovative gameplay.

One thing could have been a bit better: we feel the 4k+ max win should have been higher to fit the high variance and potential for possible monster multipliers.

All in all, we love it!
