Introduction to Rumble Kong Cashingo
Rumble Kong Cashingo is a casino slot from Alchemy Gaming that seems to be inspired by the movie character King Kong, which is an inspiration for the video game Donkey Kong. The original King Kong movie was released in 1933, and the popular theme of the giant ape in a city has been repeated many times. The first Donkey Kong video game was released in 1981, and it’s still considered one of the most classic games in history.
In this game, there’s a giant gorilla called Kong who can help you out by throwing cash bananas at the reels. He’s also supervising the Cashingo grid next to the regular grid, where bananas can be transported and awarded as soon as you land a winning bingo line.

Theme, Gameplay, and Payouts
Rumble Kong Cashingo is a video slot from Alchemy Gaming featuring 5 reels, 5 rows, and 3,125 ways to win. To the left of the reels is also a Cashingo grid with the same number of reels and rows, where yellow bananas can end up and award prizes. The Min.bet is 0.2, and the Max.bet is 25. The game has high volatility and an RTP of 96%. The max win is set to 9,000x the bet, and the hit frequency is 12.58%.
Rumble Kong Casingo is set in a tropical setting with a big brown gorilla named Kong to the left of the reels. Next to him is the transparent Cashingo grid, where yellow bananas can be transported from the regular reels. In the background, several waterfalls pour down from the mountains. Next to Kong are also piles of gold coins. To make a win, you need to land 3 or more matching symbols on adjacent reels, starting on the first reel to the left. The game is available on mobile phones, tablets, and desktop computers.
The lower-paying symbols in Rumble Kong Cashingo are 10, J, Q, K, and A. They pay between 0.8x and 1.2x the bet for a 5-of-a-kind win. The higher-paying symbols are hedgehogs, birds, lemurs, and jaguars. They will give you between 1.8x to 4x the bet for a win containing 5 symbols. The Wild Symbol substitutes all the mentioned symbols, but not the Scatter, Bananas, or Token Symbols.

What features are available in the slot Rumble Kong Cashingo?
The features are Wild Symbol, Bananas, Cashingo Feature, Hot Mode, Cash Prize, Kong’s Banana Throw, Collection Pot Feature, Wheel Bonus Feature, Cashingo Booster, Free Spins, Upsizer Feature, Bonus Recharge Feature, and Feature Buy.

Wild Symbol
The Wild Symbol appears in both the base game and the Free Spins feature. It can land on all reels except the leftmost one, and it helps complete winning combinations by substituting for all regular-paying symbols. However, it can’t replace Scatter symbols, Bananas, or Bonus Tokens.
Bananas
Yellow and green Bananas can appear during both the base game and Free Spins. The regular bananas have cash values between 0.2x and 10x the bet, and the jackpot bananas are Mini (15x), Minor (50x), Major (250x), and Grand (5,000x). Only Yellow Bananas are transferred to the Cashingo grid to the left of the reels, where they end up in the corresponding position to where they were on the slot grid.
Cashingo Feature
The Cashingo feature is available in both the base game and Free Spins. Yellow Cash Bananas and Yellow Jackpot Bananas that land on the reels are transferred to matching positions on the Cashingo grid, which is in a 5x5 pattern, just like the regular grid.
If a Cash Banana is already in a position, any new banana’s value will be added to the present value. Completing a horizontal, vertical, or corner-to-corner diagonal line of 5 Bananas awards a cash prize. Up to four winning sets can be completed on a single spin.
When a Banana is part of more than one completed set, its value contributes to only one prize. All Bananas involved in a win are removed from the grid. If a Jackpot Banana is part of a winline, its prize is also awarded. Only one Jackpot Banana can be present at the same time.
Hot Mode
The Hot Mode can be activated randomly in the base game or after a 24-hour countdown. The first countdown starts after the first base game spin is completed. It can also begin if Free Spins are purchased and finished before any regular spin is played. Once the countdown ends, Hot Mode starts automatically on the next base game spin.
Randomly triggered Hot Mode lasts between 5 and 10 paid spins, while countdown-triggered Hot Mode always lasts 10 spins. During Hot Mode, the chance of completing Cashingo wins and collecting cash prizes is much higher. Extra Bananas are added to the reels, and only Bananas can land. All other symbols are replaced by blank spaces, which have no value and cannot create wins.
Cash Prize
Landing two or more Cash Bananas consecutively from the leftmost reel creates a cash prize, awarding the total value of all involved bananas. If a Green or Yellow Jackpot Banana appears within a winning sequence, the related jackpot is awarded.
Kong's Banana Throw
Kong, the monkey to the left of the reels, may randomly throw Bananas onto the reels on any spin. He can put both Green and Yellow Bananas in random positions to improve your chances of scoring wins.
Collection Pot Feature
Collecting Bananas gives a chance to increase the Collection Pot and may also randomly trigger the Collection Pot feature. When the feature activates, additional Bananas are placed in random reel positions, and the Collection Pot resets. Neither the Banana collection nor the Collection Pot feature can occur together with any other feature.
The Collection Pot shown on screen is for entertainment purposes only and does not influence feature outcomes.
Wheel Bonus Feature
You trigger the Wheel Bonus Feature by collecting at least one Bonus Token on every row. You collect the tokens on multiple spins, and only one can land per spin. The bonus wheel contains 12 guaranteed prize segments:
- Grand Jackpot: 5,000x.
- Major Jackpot: 250x, with a possible 2x multiplier.
- Minor Jackpot: 50x, with possible 2x or 3x multipliers.
- Mini Jackpot: 15x, with possible 2x, 3x, or 5x multipliers.
- Free Spins
- 500x Free Spins
After the wheel stops, Kong may randomly move the result up or down by as many as two positions to improve the prize.
The regular Free Spins use the Cashingo multiplier collected in the base game, and the special 500x Free Spins feature doesn’t reset the booster or multiplier. This feature is available only in the base game, and no other feature can trigger at the same time.
Cashingo Booster
Landing one or two Scatter symbols in the base game adds them to the Cashingo Booster, which can increase the Cashingo Multiplier in the Free Spins, which starts at 10x and can reach 200x. The booster becomes full after collecting ten Scatter or Super Scatter Symbols, which will reset the booster and increase the multiplier by 10x.
The next Free Spins feature starts with the stored multiplier randomly placed between 2 and 20 positions on the Cashingo grid. The 500x Free Spins feature automatically awards a 500x Cashingo multiplier. Unlike the standard Free Spins, this special version does not reset the booster after completion.
Free Spins
You trigger 8 Free Spins by landing 3 Scatter Symbols anywhere on the reels. If one of the triggering Scatters happens to be a Super Scatter, you’ll trigger the 500x Free Spins. The current Cashingo multiplier is randomly distributed across between 2 and 20 positions on the Cashingo grid, and extra multipliers may randomly appear and be added to new or existing grid positions during the feature.
When a Cash Banana becomes part of a winning set, any multiplier attached to that position is applied to its cash value and then removed. Jackpot prizes cannot be multiplied, which means that Jackpot Bananas and multipliers cannot occupy the same position.
Additional free spins can be awarded through +1 and +2 Extra Free Spins symbols.
Upsizer Feature
The Upsizer Feature pops up immediately when you trigger the Free Spins, offering you to buy a larger Cashingo multiplier before the Free Spins start. The Upsizer Feature is not available for the 500x Free Spins.
Bonus Recharge Feature
You may be offered the possibility to continue the Free Spins by buying an extra spin for a preset prize when the feature ends. You can either accept and pay the cost for another spin or deny and return to the base game.

Feature Buy
You can go straight to the free spins with a 50x Cashingo multiplier for 50x the bet. Playing the feature with a 100x multiplier costs 90x the bet, and a 200x multiplier will set you back 175x the bet. To go all in, and activate the 500x Free Spins, you’ll have to pay 450x the bet.
Final Thoughts on Rumble Kong Cashingo
Rumble Kong Cashingo kicks off by introducing you to a banana-throwing monkey. The jungle theme with the cash-loving gorilla is playful but far from groundbreaking. You can tell that the game borrows inspiration from giant ape stories, but it doesn’t tip over to nothing but nostalgia.
One thing that sticks out is the Cashingo grid. Alchemy Gaming has never used the feature before, but we have played releases of Cashingo games from other Games Global associates, such as Stormcraft Studios’ Mermaids Millions Cashingo and SlingShot Studios’ Eruption Blaze Cashingo. In this game, all yellow banana symbols that don't take part in a win on the regular grid will be moved to the Cashingo grid, where they will pay cash wins if you line them up on a bingo line. It’s satisfying to watch the bananas stack up and connect into a paying bingo line, even if it doesn’t always lead to massive wins.
There’s a lot of variety feature-wise, although not all features are as exciting. Kong’s Banana Throw and Hot Mode are examples of features that feel kind of mellow, although they can burst into excitement every now and then.
Rumble Kong Cashingo from Alchemy Gaming is a monkey-themed slot that stands out with engaging banana mechanics.
