Rio Fever Slot Review

The Rio Fever slots game can be found at online casinos offering Paiplay. Pariplay now publish the slots house edge information of all their games as a standard. You can find this by clicking the ‘+’ symbol at the bottom left hand corner of the game window then clicking ‘?’. Within this help file you’ll find the RTP information. As such we can say that the House Edge of Rio Fever is 5.30%. As the help file does not list a range of possible figures we assume that this game is not configurable and should be the same at every casino you find it at.

It’s Carnival time and the party’s just getting going!

Rio Fever is a 5 reel game and each reel is 4 symbols high. The game uses 40 paylines and you can bet one coin on each of the paylines.

The ‘Wild’ symbol is Wild.

There are four bonus features when playing Rio Fever. The first bonus feature is activated randomly and when this happens fireworks will shoot over the reels and transform random symbols into Wild symbols for the duration of that spin.

The second bonus feature is triggered when you receive 3 or more of the full two symbol high ‘Bonus’ symbols anywhere on the reels. When this happens you will be taken to a new screen showing a prize wheel and you are awarded one spin of the wheel. You can win the following:

– A multiplier that will be applied to the wager that triggered the bonus feature.

– Wild Ginga – You will be awarded 3 free spin. Each spin up to 5 reels will be turned into Wild reels. The bonus feature cannot be retriggered during these free spins.

– Samba Parade – You are awarded 7 free spins. During the free spins one locked Wild symbol is added to a random position on the reels each spin and remains in place until the end of the free spins. The bonus feature cannot be retriggered during these free spins.


Rio Fever is a problematic release in the modern slots market. Graphically it’s reasonable without being stunning. Gamplay wise, the bonus features do not offer anything particularly original and most players familiar with slots games will have seen these types of features before. But the biggest let down is a House Edge that is inflated way above the range that is commonly being utilised in modern slots releases. So here we have a game that isn’t anything special to look at, isn’t anything special to play and that is charging you significantly more than a great many far better games. That doesn’t seem like a good combination to us.
