Boombastic slot by Merkur brings us back to the fun and colour of fireworks and rockets in a cartoon way, with clouds of smoke billowing out behind our plain blue reels although you get a silly popping sound when they stop and classical music when they spin. Why there are no sounds appropriate to the theme as we have with Netent's classic Wild Rockets, Leander's Fortune Fireworks and even IGT's poor Fantastic Fireworks, I do not know because it's somewhat lacking without them. Nevertheless despite Merkur's typically basic graphics, does this slot have a boom or a bang in store for our bankroll?
There are 10 fixed pay lines over 5 reels of 3 rows apiece here on Boombastic slot with single or double symbols on the reels aside from the stacked Rocket Wilds which can appear on the middle 3 reels. We don't need scatters as we'll see shortly but the 5-of-a-kinds can be good for our 20-coin bet with the Display Box paying 500x bet, Triple Firework 200x, Winged Firework 100x, Multi Tube 50x with six card values paying either 20 or 12x bet for a full line of 5. Winning symbols will explode away and more cascade down from above. There's no multiplier for successive cascades but Wilds will shoot away spectacularly if appearing stacked to clear the whole reel.
You don't have scatters but what you do get is a line of matchboxes above the grid. There are two loose matches to the right of them too. The matchboxes are overlaid with 3,10,20,30,40 and 50 and once you get a win you'll ignite the first match, a second winning cascade will ignite the second and a third will get you on to the matchboxes to land you 3 free games, a fourth 10 and so-on according to the scale. You can retrigger too and there is a decent chance of this as the incidence of fully-stacked Wilds on the centre reels increase in free games.
Despite the rather childish appearance and basic graphics, Boombastic slot can really make your balance skyrocket in those free games with those large line pays and extra Wilds in action. The only issue I have is that in trying to make the free games more frequent they are almost always with only the basic 3 triggered and sometimes 10 if you're lucky, any higher is very rare. You will rack up some good wins though if you do get more than 10 and with a 96.00% RTP in play there is real potential here which belies the game's appearance. It's about the worst fireworks-themed slot to look at I have ever seen, yet this display could really be worth attending...
