  • Adorable theme and visuals
  • K-Cash feature adds a new level of excitement
  • Megaways gaming mechanism
  • Maximum win capped at 5,000x the bet



Kalamba Games decided to join the Megaways bandwagon and add yet another slot machine with this popular gaming mechanism. Rumble Rats Megaways is a perfect mix of animal slot machines and medieval games. It grabs your hand and attention and leads you down to the kitchen, where a gang of cute rats try to steal all the cheese there is.

While the cat’s away, the mice will play, but beware – there is a sneaky tomcat just waiting for them to make the wrong move! This charming game has an abundance of free spins and the cool K-Cash feature, but can it live up to our early expectations? Let’s head down into the kitchen and find out…

Theme, Graphics & Soundtrack

Rumble Ratz Megaways initially comes across as a feel-good animal-themed slot machine that conjures up the smell of a delicious stew cooking on an open fire, mature cheese, and garlic lingering in the air. The cosy atmosphere is accentuated by cute characters who evoke the same emotions as Remy from Disney’s Ratatouille.


The contemporary medieval music, combined with delightful sound effects, makes the entire game feel very cartoonish, so if you don’t mind some cuteness in your life, this could be right up your street. Despite all this, it is hard to call the game memorable. Visually, it just doesn’t quite have the potential to leave a lasting impression (unlike the Disney classic!).

How to Win

Rumble Ratz Megaways, just like the name suggests, has a Megaways gaming mechanism with a number of paylines that ranges from 4,096 to 46,665. As usual in these types of games, wins are triggered when you land at least 3 of a kind on a payline.

The only exception to this rule is the Rat King, a symbol that activates a payline with only 2 symbols. It will reward you between 0.4x and 5x the bet. The lowest paying symbols are 9s and 10s, delivering only between 0.08x and 2x your stake.

The betting limits for Rumble Ratz Megaways are between £0.25 and £37.5 per spin.

Rumble Ratz Megaways Free Spins

Land 3, 4, 5, or 6 scatter symbols, and you will get not only 2x, 5x, 10x, or 15x the bet, respectively, but also 3 free spins! If you get a K-Cash symbol in a reel which is not 6 positions high, the number of spins resets back to 3. By removing the blocked tiles, you help the increasing multiplier grow up to x10 the bet!

Rumble Ratz Megaways K-Cash

You have probably noted that some positions are blocked, which is where the K-Cash steps in. Land this special symbol in a reel with blocked positions and help the money prize grow. To trigger the money prize, you must remove all blocked positions and land one extra symbol to trigger the cash win.

Rumble Ratz Megaways Hyper Bonus

In Rumble Ratz Megaways, it is also possible to purchase three kinds of bonuses:

  • 3 free spins with up to x10 K-Cash multiplier
  • 3 free spins with up to 7x K-Cash multiplier
  • 3 free spins with up to 4x K-Cash multiplier

Our Verdict

Rumble Ratz Megaways is a cute, albeit not a very memorable game. Despite having some neat features, they tend to take ages to be triggered and are not exactly lucrative when they do come around.

It must also be said that the blocked positions can leave you frustrated at times, especially considering the high volatility. The maximum prize leaves you feeling a bit deflated as well; wins are always welcome no matter the size, but there are much bigger wins out there.

Come play the free demo to see what you think, or how about spinning Golden Mouse, Mouse and Cat or Copy Cats instead?
