Slot Details

Rumble Ratz Megaways is a video slot with six dynamic reels featuring four to six rows and 4,096 – 46,656 ways to win. Pays are awarded for two to six matching symbols landing on adjacent reels from left to right only. You can join the cat on the chase from 0.25 to 37.50 credits per spin. The game has high volatility with an RTP of 96.21%. Lower settings might offered, always check the help files for the currently active RTP.

The dining hall of a medieval house with an open fireplace and a table prepared for the next meal serves as the background to this rodent-hunting reel chase. The reels are framed by wooden poles while various cheese plates at the top act as K- Cash collectors that the rats caught in the shaft below are aiming to reach for a feast on the tasty cheese. The cat will make random appearances throughout the gameplay mostly accompanied by her meows. A medieval soundtrack provides the main audio.

The pay symbols start at the low end with card royals from 9 through to A, awarding 2x to 2.6x your bet for a single six of a kind. They are followed by a gang of five rats on blue, green, turquoise, red and golden backgrounds. Hit six across the reels to win 3x to 5x your stake.

The wild is carved from pieces of cheese, appearing on the four centre reels in the base game and on all but the first in the free spins and performing the usual substitutions duties. A wooden plate with cheese marked with a random coin value is the K-Cash symbol while a door to the cheese stash acts as the scatter.

Rumble Ratz Megaways Slot Features

Kalamba Games is not exactly a frequent Megaways provider although they were one of the first to sign a licence. Some players might still remember or even play at times Machina Megaways, which is the only title on our list to date. Rumble Ratz Megaways is now the next addition and is taking us from a sci-fi inspired adventure to a cheese pantry filled with hungry rodents. Reason enough to take a closer look.

Upon loading the game for the first time, the number of ways will be randomly chosen for each bet size with the minimum being 4,096 ways. The remaining symbol positions are covered by an elevator-style crankshaft, each manned by a rat that may set it in motion when a K-Cash symbol lands below it. Each move will gradually increase the number of betways up to the maximum of 46,656. Once a K-Cash prize is collected, the respective reel is reset to four symbols and the two top positions covered again by the crankshaft.

Rumble Ratz Megaways Slot - K-Cash Collection

Since Kalamba Games decided to forgo the cascading symbol mechanic, the base game relies mostly on multi-way combinations to hit big wins. The second opportunity is the K-Cash collection, although that is in play in the free spins too. You will observe a K-Cash Meter at the top of every reel, each with a random starting value. Any time a K-Cash symbol lands (the cheese platter marked with a coin value), it will be collected in the meter above it.

In the base game, any collection can also trigger the crankshaft. The rat will move it then one position upwards and open one additional symbol on the respective reel. Once fully open, the next trigger will see the rate hopping onto the K-Cash Meter plate to feast on the accumulated cheese. Any time a K-Cash Reset Symbol lands on the following spins will see the cat chasing the rat away and awarding the collected amount as an instant cash prize. The height of the respective reel is then reset to four before the next spin starts. The progress is stored separately for every bet size and between gaming sessions.

Rumble Ratz Megaways Free Spins

Hitting three or more scatters anywhere on the reels will trigger the Free Spins feature and award a coin win between 2x and 15x your bet. Each K-Cash meter will start with a random coin value irrespective of what they displayed in the base game, typically at 1x bet. In addition, the game grid is set at 6×4 with 4,096 ways and the two top positions on each reel covered with the crankshaft.

Initially, 3 Free Spins are awarded and any K-Cash symbol that appears on a reel which is not fully opened yet will reset the counter to three. All K-Cash values are accumulated in the meters throughout the feature. Expanding two reels to the maximum will start increasing the K-Cash Multiplier shown to the right (desktop). For a 3-scatter trigger the steps are x2, x3 and x4. The maximum in a standard feature is x4 while up to x10 is possible for the top feature.

The bonus round ends when you run out of spins. In the best case scenario, that will happen 3 spins after the last reel has been expanded as the counter will no longer reset. No other retriggers are available. The coin values on the K-Cash Meters will be added up before being multiplied by the achieved factor. Any way wins hit on a free spin will go on top for the total win from the round.

Kalamba Games included a choice of three HyperBonus Buy options for players in unrestricted jurisdictions. The price tags are 60x, 100.4x or 140.6x your base bet, offering three levels with up to x4, x7 and x10 K-Cash Multipliers respectively. Once a purchase is confirmed, the game will instantly start the bonus feature.

Final Verdict

Rumble Ratz Megaways is a fun reel chase with a to-date unseen mechanic to collect coin wins. Kalamba Games simulated very creatively the rodents’ hunt for their favourite snack as they patiently wait to move the evelator up to the top of the reels for a feast on the bulging cheese plates. Not missing is the ever-vigilant cat that will chase them away once a K-Cash prize is collected. Very entertaining with an estimated top win potential of up to 5,000 times your bet. We will confirm the exact value once we receive the details.
