Ka-Boom is an online slot game by software developer Merkur that focuses on none other than fireworks and explosives. But we’re sure you were able to deduce as much from the game title already. The backdrop here clearly demonstrates that some of the explosive devices had already gone off. So, there are a number of bright and colorful clouds behind the reels. Notice also that the style of this slot is all classic cartoon, or comic book even. It adds a nice touch to the overall appearance and makes it all seem even more whimsical and fun. That same style continues onto the reels and into every single one of the rockets, dynamite sticks and other items that have the potential of going ‘ka-boom’. And wait until you start playing, because you will get to see this entire arsenal explode and that’s part of the whole experience with this slot.
