We all hope for big prizes while playing online slot machines, and they come with all kinds of titles. So does Ka-Boom give us a clue to how this game might work? One quick look at the screen reveals it does, as there are various fireworks in action here.
You can bet between one cent and two dollars on each of the five lines in play. That's not many lines, but at least you get some good betting options. The bonus symbol is the game's substitute and it can replace everything else you'll come across. Two of them will trigger the Ka-Boom bonus, but there is no inkling of what this might be.
They've not included much detail in the paytable here, which is good if you like to be kept in the dark about bonuses but not so good if you don't! Maybe trying to play Ka-Boom in free mode to start with is the best shot with this title.
