Congo Cash takes a slightly different approach to keeping things interesting. Instead of putting all of its focus on the winning combinations, it encourages us to keep an eye on the Jewel Board sitting above the reels. Every collected jewel brings another reward within reach, whether that turns out to be a cash prize, a fixed jackpot, or Bonus Spins.
Fans of online slots with progression mechanics will find plenty to keep an eye on here. The collection system remains active throughout the session, giving the game a steady sense of momentum without making the mechanics difficult to follow.
Dense greenery surrounds the playing area with tiny butterflies flying around, and animal symbols also contributing to the rainforest theme. The gorilla has the highest regular payouts, followed by the leopard, baboon, lemur, and tree frog, while the remaining symbols use standard playing card values.
The Jewel Board above the reels ends up becoming the real centre of attention. Watching new jewels appear and then disappear once they are collected gives the game a sense of progression. We found ourselves looking at them almost as often as the reels because every collection could move us closer to another reward.
The payout values below are based on a total bet of 1.
The Wild symbol appears on reels 2, 3, 4, and 5 and substitutes for all regular symbols except the Butterfly and Congo Cash symbols, helping complete winning combinations across the 432 ways to win.
One small detail we appreciated was that the Jewel Board stays exactly where it is from one spin to the next. It gives the game a feeling of progression because uncollected prizes remain on the board instead of disappearing straight away. New jewels appear above reels 2, 3, and 4 before every spin, carrying either cash prizes, Bonus Spins, or fixed jackpots. Cash rewards range between 5x and 200x the total bet, while the Minor, Major, and Grand jackpots are worth 25x, 100x, and 2,000x. The board resets only after every jewel has been collected or the stake is changed.
Butterfly symbols appear only on reels 1 and 5, while Congo Cash symbols land on reels 2, 3, and 4. When two Butterfly symbols appear together with at least one Congo Cash symbol, the jewel above the corresponding reel is collected. Since multiple Congo Cash symbols can land during the same spin, up to three jewels may be collected at once.
Collecting Bonus Spins jewels awards between 8 and 100 Bonus Spins. The feature starts with the combined number of Bonus Spins collected from the Jewel Board. During the round, at least one Wild symbol is guaranteed to appear on every spin on the reel where the Bonus Spins jewel was collected. The Board remains active throughout the feature, allowing additional prizes to continue being collected.
Three fixed jackpots can be won through the Jewel Board. The Minor Jackpot awards 25x the total bet, the Major Jackpot awards 100x the total bet, and the Grand Jackpot awards 2,000x the total bet whenever the corresponding jackpot jewel is collected.
Five reels and 432 ways to win provide the foundation for the gameplay. Matching symbols pay from left to right across adjacent reels, and whenever several winning ways are formed using the same symbol, every payout is added together.
After almost every spin, there was often another prize sitting there waiting to be collected. Instead of only looking for winning combinations, we found ourselves checking whether another jewel had been collected. The Wild helps complete regular wins by substituting for every symbol except the Butterfly and Congo Cash symbols, and because the collection system carries into Bonus Spins, the gameplay feels consistent from beginning to end.
We never felt as though every spin had to produce a big win because the Jewel Board usually gave us something else to look forward to. Rather than concentrating all of the excitement into a single feature, the Jewel Board creates a steady sense of progression throughout the session. One thing we noticed fairly quickly was how often our eyes drifted above the reels. Waiting for another jewel to be collected added its own anticipation, even during spins that were otherwise fairly uneventful.
That steady progression ended up being the part of Congo Cash we enjoyed most. It gives the game a clear identity without asking us to keep track of lots of different mechanics.
