Bangers and mash
Ka-Boom is played on a 5x3 grid of black reels against what looks like a huge explosion. The graphics aren’t the most amazing we’ve ever seen but the various rockets are quite rewarding paying out 1,000 coins for five on a payline when you’re playing at the maximum bet. The big crate of fireworks doubles that prize to 2,000 coins for five symbols on a winning payline.
As usual with games from this developer, the user interface is flawless, allowing you to set your line bets, autospin, explore the paytable and go all in with a bet max at the touch of a button. Bets range from 0.01 coins to 2 coins for a maximum bet of 10 coins per spin. It doesn’t seem like much but you’ll need to be spinning at the maximum bet for the biggest rewards.
The big bang
Ka-Boom only has one bonus feature but it's a cracker. Land the bonus bomb symbols on reels one and five and you’ll enter the big bang bonus feature. With a huge Ka-Boom, every symbol on the reels will explode and you’ll be awarded their value making this potentially extremely lucrative. Still want more? Then just like every other Merkur slot, you’ll have the opportunity to gamble your winnings. Go double or nothing on the turn of a card, or try your luck on the gamble ladder. If you have the skill and timing you can do well with this feature, but if your luck just isn’t running you can also hit the collect button and keep the lot.
Bang for your buck
HTML5 free slots games are optimised to run in a smooth and hassle-free way on your mobile and tablet devices whether they run iOS or Android and Ka-Boom is no different. In some ways the lo-fi graphics and simple and straightforward gameplay work even better on your smartphone, making Ka-Boom ideal for a cheeky spin on the move.
Ka-Boom or Ka-blooey?
You can’t fault this developer for trying to come up with something different. They have a whole portfolio of slots with clever bonus features that put a spin on the way you play. If you prefer more bells and whistles from bonus gameplay then Ka-Boom won’t be the slot for you. But if you like some wanton destruction and a big bang then Ka-Boom’s bonus feature definitely delivers! Otherwise, you’ll boost your payouts with the two gamble features as this is a low to medium volatility slot that relies on the bonus to deliver the goods.
