Play Ka-Boom for Free

Ka-Boom is a 5-reel, 5-pay line slot machine. You can adjust both pay lines and the coin value to suit your budget. Minimum stakes are 0.05 for all pay lines and the maximum is just 10.00 a spin.

The display panel to the lower of the screen highlights your cash balance, bet value and last win. The pay table is housed to the lower left of the reels and gives a brief insight into what the game has to offer – along with the payouts for each symbol.

Merkur have designed Ka-Boom to look as explosive as possible. Behind the reels are red, orange and yellow explosion images – just like you’d find in a superhero comic book. The reels are situated to the center of the screen and are black. Colors come from the various symbols that can be found on those reels, which are; box of rockets, bomb, yellow and red explosives, green dynamite, blue explosive box and two symbols bearing different multi-colored rockets.

To get your hands on the 2,000 non-progressive jackpot, you will need to charm 5 of a kind of the box of rockets onto your pay line. The second highest symbol are the multi-colored rockets which offer 1,000 for matching 5 on your active pay line.

When it comes to slot features, there isn’t much to explain. Firstly, there is a gamble feature – one that you can expect with all Merkur slot machines. Any win hat you manage to spin in on your reels will trigger the gamble option.

The buttons beneath the reels will change to show a gamble button – click to go for more or keep your original winnings, it’s up to you. If you gamble, you will be taken to the ladder of wealth. You have to click the button on your screen to try and climb up to the maximum that’s on offer, but be careful because you can slip down and lose the lot. Cash out at any time if you feel like lady luck isn’t on your side.

The bomb bonus symbol is a wild and will replace other symbols on the reels to help form winning combinations.

If you can spin in a bonus bomb on reels 1 and 5, this will award the bonus feature. This feature is amazing as it explodes all of the symbols already on the reels and awards their value. An example of this is we staked 10.00 a spin and when we triggered this bonus we accumulated 440.00 in wins.

Fair play to Merkur because they have created a slot machine that really packs a punch. On first impressions, the slot machine is basic and doesn’t really offer much but when you start to play, only then do you realize that you can rack up some huge wins from the very little features on offer.

This low to medium volatility slot machine offers the majority of the wins via the bonus feature. Get two bombs on the reels and you know you are in for some explosive wins. You don’t have to bet big stakes to win big with this slot machine, you just have to play and look for the bonus feature.

We found plenty of wins would fall on the reels but the lucrative wins did come from the bonus round. The gamble feature is a strange one because if you don’t decide to gamble within a few seconds it takes it upon itself to credit your account with your original winnings. Make sure you press gamble as quick as you can if you wish to try and win more. Bear in mind that the gamble feature is a good way of losing your money, as there is no skill required in order to win – you click the button and the light will either jump up to a bigger win or slide down and down until you eventually lose the lot. You can collect your winnings at any stage of the gamble feature.
