Kong Cash CASHINGO Symbols & Pay Table

There are 16 symbols in total. Low-paying symbols are represented by card ranks, while premium symbols include Beavers, Toucans, Lemurs, and Tigers. The Tiger is the highest-paying premium, awarding up to 4x for five of a kind. Special symbols include Wilds, Bonus Tokens, Scatters, Super Scatters, Cash Bananas, Jackpot Bananas, and Green Cash Bananas. Wilds appear on reels 2 to 5 and substitute for all regular symbols except Scatters, Bananas, and Bonus Tokens.

Cash Grid Feature
During both the base game and Free Spins, Yellow Cash Bananas and Yellow Jackpot Bananas are transferred to a separate 5×5 prize grid that mirrors the reel positions. If a Cash Banana lands on an occupied position, its value is added to the existing Banana. Completing a horizontal, vertical, or diagonal line awards the combined value of all Bananas in that line, with up to four winning lines possible on a single spin.
Cash Bananas reveal random values between 0.2x and 10x the stake, while Jackpot Bananas award one of four fixed prizes:
- Mini: 15x
- Minor: 50x
- Major: 250x
- Grand: 5,000x
Only Bananas that contribute to a completed line are removed, allowing the remaining symbols to continue building towards future payouts.
Hot Mode
Hot Mode can trigger randomly during the base game or automatically after a 24-hour countdown. During the feature, only Bananas and blank symbols appear on the reels, significantly increasing the chances of completing prize lines and collecting cash rewards. Random Hot Mode lasts between 5 and 10 spins, while the timed version always awards 10 spins.
Cash Prize Feature
Landing two or more Cash Bananas consecutively from the leftmost reel awards an instant cash prize based on the combined Banana values. If a Jackpot Banana forms part of the sequence, the corresponding jackpot is also awarded.
Banana Throw & Collection Pot
During the base game, the main character can randomly throw additional Bananas onto the reels, creating more opportunities to complete prize lines. Collecting Bananas also contributes towards a Collection Pot. When activated, extra Bananas are added to random reel positions before the pot resets.
Prize Wheel
Bonus Tokens are collected across multiple spins. Once at least one token has been collected on every row, the Prize Wheel is activated.
The wheel guarantees one of several rewards, including:
- Mini, Minor, Major or Grand Jackpots
- Free Spins
- Enhanced 500x Free Spins
After the wheel stops, the result may randomly be nudged to a higher-value prize.
Multiplier Booster
Landing one or two non-triggering Scatter symbols fills a multiplier booster. The booster starts at 10x and increases in stages up to 200x. When Free Spins begin, the accumulated multiplier is randomly assigned to positions on the prize grid, multiplying qualifying Cash Banana rewards. The enhanced Free Spins feature instead begins with a fixed 500x multiplier.

Free Spins
Landing 3 Scatter symbols awards 8 Free Spins. If one of the triggering symbols is a Super Scatter, the enhanced 500x Free Spins feature is activated. During Free Spins, multiplier values are randomly distributed across the prize grid and can continue to increase throughout the feature. Extra Spin symbols may also appear, awarding +1 or +2 additional Free Spins. The feature cannot be retriggered.
Bonus Options
Before Free Spins begin, players may have the option to purchase a larger starting multiplier. After the feature ends, an optional continuation feature may also appear, allowing players to extend the bonus from its current state for an additional cost, depending on regional availability.
Buy Feature
Players can purchase direct access to the bonus with different starting multipliers:
- 50x Multiplier – 50x stake
- 100x Multiplier – 90x stake
- 200x Multiplier – 175x stake
- 500x Multiplier – 450x stake
Purchasing a feature does not reset the multiplier booster, allowing progress to carry over into future bonus rounds.
