Rumble Ratz Megaways Features

In the base game and free spins, players can collect cash prizes from the K-cash symbols (aka the cheese). The collected amount is highlighted at the top of the reels. If the column height is less than 6 rows, then the game randomly decides whether the K-cash symbols will expand the column it appears on. During the base game, if the K-cash reset symbol appears, then the column height is reset to 4 rows.

The free spins round is triggered by landing 3 or more bonus symbols (aka the cat with cheese) to award 3 initial free spins. This can be reset when a K-cash symbol lands and this symbol is multiplied by the multiplier highlighted on the right side of the screen.

Finally, non-UK players will be happy to find out that there are bonus buy options available. Players can select three different free spin options with different multipliers for a cost.

Rumble Ratz Megaways Review

For centuries rats and cats have been constant foes fighting for dominance. Throughout history, cats have often been the most victorious but that all changes with Rumble Ratz Megaways.

Developed by Kalamba Games, Rumble Ratz Megaways arms a bunch of cute rats and prepares them to fight the mighty cat. Playing on 6-reels with up to 46,656 ways to win with Megaways, this game features K-cash as well as free spins leading to victorious wins.


As the slot opens up, it's clear that Kalamba Games has put in a huge amount of effort to release something that looks fantastic. Firstly, the game is set in a baker's kitchen and it seems that the kitchen is quite dated with cobbled flooring and brick walls.

Surrounding the reels, there is a pot brewing as well as a sinister cat looking around for the rats. At the top of the reels, there are rats eating cheese as well as adorable rats on the reels with weapons.

This game definitely embodies the perfect spirit of cats vs rats but is done with a tongue-in-cheek style that is brilliant. The music throughout the slot is quite whimsical with guitars, bells, drums and other soft instruments to create something magical. Of course, this is perfected by the noises of the aggressive cat throughout spins.


Unlike most Megaways slots, this game contains up to 46,656 ways to win instead of 117,649 ways to win - but it never feels like the game is diluted. There are features throughout the base game and the bonus rounds with the K-cash buttons.

Anything the player will need can be found at the bottom of the screen with the spin button as well as the bonus buy option for non-UK players.

Win Potential

Rumble Ratz Megaways has a mixed win potential but starts off strong with a great RTP of 96.21% as well as a high volatility level leading to larger wins but less frequently.

However, the maximum win for this slot is only 5,000x the stake which is low for a modern online slot but can still lead to some decent wins. It's just worth mentioning the amount as some high rollers will be put off by this low amount.

Our Verdict

There aren't many rat slots out there but Rumble Ratz Megaways is easily one of the best. Not only is the design absolutely stunning and charming, but the gameplay is vibrant and full of satisfying moments.

The only real issue is the low win potential with the maximum win but it's nothing too low to be completely off-putting. Slot enthusiasts looking for an exciting slot with rats vs cats, then look no further than Rumble Ratz Megaways.
