A lot of times, Kalamba Games prefer to do things their own way. Their own themes and their own features, but they also have fallen into the charming arms of Megaways. We don’t think this mechanism needs an introduction because by now everyone and their moms have heard about it, as the supply of these Megaways games is vast. Interestingly enough, Kalamba Games haven’t been overly keen on using Megaways, as they don’t have a wide portfolio of these games, but now the day has come when we’re seeing another Megaways game from Kalambians, or is it Kalambinians? Regardless, welcome Rumble Ratz Megaways.

The title of the game gives away the main characters of this story, which are rats. Yes, the rats have infested a kitchen, the same way Ratatouille did back in his days of fame. Rumble Ratz Megaways brings that unique Kalamba Games visual style and it also implements some extra features added to the presence of Megaways. Kalamba + Megaways is not a common combination but perhaps there is something to it. We’re about to find out.

Gameplay and Payouts

There’s one thing that we have noticed on many Kalamba Games slots. Visually, there is often this contrast between the warm orange and cold blue tones. The same can be perceived in Rumble Ratz Megaways where the warm kitchen fire is on one side, whilst the other side seemingly portrays this cool blue light that comes from the window. It’s a nice cosy kitchen, nothing crazy. During the bonus game, we move to the cheese cellar, where rats have even managed to trap the cat. It’s certainly one light-hearted presentation.

Maybe once in a blue moon, you will spot Kalamba Games using a regular game layout, but this is not the day, as they are using a hefty 6 by 6 playing field. This, of course, is also because of the added Megaways mechanism, which brings the payline tally up to 46,656. If we’re looking at the Rumble Ratz paytable, the low symbols are wooden royals and the high symbols are different rats, each specializing in their own kitchen skills. K-cash symbols are pieces of cheese, although, in reality, rats are not even that fond of it, we have to keep traditions strong.

Kalamba Games have produced some slots with huge payouts and Megaways slots, in general, are known for producing some jackpot-worthy casino games, so a combination of both worlds would bring something spectacular, right? We thought so too, but it’s not entirely the case with Rumble Ratz Megaways. The max win on this slot is 5,000x, which, by all means, is a great win, but Megaways have provided bigger results before. The RTP on Rumble Ratz Megaways is 96.21%. The bet range is a bit peculiar, ranging from 0.25 to 37.50, but it should suffice for most players.

Bonus Features

Rumble Ratz Megaways is a bit different from the usual Megaways experience. We get these blocker tiles, which can be unlocked by K-cash symbols. When the reel is fully unlocked, then a K-Cash symbol can also reset the blocked tiles, so it can be medicine and poison at the same time, sometimes the line is very thin.

3 or more scatters will do the trick to trigger the Rumble Ratz Megaways bonus feature. K-cash meters are equipped with additional multipliers and like before, K-cash symbols can open up the blocked tiles. With each removed blocker tile, the Free Spin amount resets back to 3. When the reel opens up fully, it increases the progressive multiplier. The free Spins bonus feature can also be purchased with the HyperBonus feature, which is present on all Kalamba Games slots.

Rumble Ratz Megaways is a slot that doesn’t excel in any specific parts. We did enjoy the light-hearted presentation, but it’s one that comes and goes. It’s fun for a moment, but after a while, that appeal wears off. Rumble Ratz is very far from a typical Megaways experience. There are no classic cascades or regular progressive multipliers, instead, Kalamba have tried to craft something of their own, while still maintaining that Megaways name. The end result could have been better, as Rumble Ratz can provide some dull moments and truly massive payouts feel a bit out of reach.

If we look at it from a regular casino game perspective, the 5,000x max win seems nice, but Megaways slots are famous for their potential, so why are we not seeing something even more explosive from Kalamba? For now, this question remains unanswered, but perhaps in the future, Kalamba Games can follow up with another Megaways treat.
