Rio Mystery Night review

Theme and Style

Rio Mystery Night is a simple classic slot with a theme based around Carnivale in Rio de Janeiro, the popular tourist city in Brazil.

The reels are full of tambourines, masks, dancers, and toucans, while the background is a city street lined with particolored bunting. The effect is celebratory and fun and should appeal to players who want a slot with a theme that is a little exotic and a lot of party.

Graphics, Sounds and Animations

The graphics are pretty straightforward, done in a semi-realistic art style with lots of the blues and purples of a nightscape mixed with the more garish elements of Carnivale.

There are parade dancers on the reels as well as tropical birds and brightly colored versions of the ace to ten symbols.

The animations are simple and highlight the action well. In particular, the fun wave of the feathers when a Scatter symbol lands is especially appealing.

The music is a little less upbeat than you might expect for a slot with this theme, but it combines with the win and spin sounds quite nicely and is never bothersome.

Gameplay

Rio Mystery Night slot has five reels each of which sports three rows of brightly colored symbols.

There are ten pay lines which are fixed, meaning the player cannot adjust the number of lines they play.

A gamble feature allows you to play double or nothing with any wins you might earn. You can choose whether a card will be red or black and then flip it over to see if you win and double your money or lose and lose it all.

The maximum win on any given round is capped at 2,500x of the player's bet.

Wilds, Bonuses and Free Spins

Rio Mystery Night slot uses a Wild symbol, a Scatter symbol, and a separate Bonus symbol.

The Wild symbol substitutes for all symbols except for the Scatter and Bonus symbols. Wilds do not appear on the first reel.

Scatter symbols have a beautiful Carnivale mask on them, and pay out for five or more Scatters anywhere on the reels.

When three or more Bonus symbols land anywhere on the reels, it triggers the Free Spin bonus. Three symbols award the player 8 free spins, four award 10, and five award 12.

During the free spins, the highest-paying symbol, the Dancer, becomes a three symbol high stacked symbol. When it is part of a win, the stacked Dancer symbol is nudged to fully cover the reels, potentially increasing the number of win lines for which the player might earn a payout.

Bet Sizes, RTP and Variance

The return to player (RTP) of Rio Mystery Night is 96.01%. This is as close to our yardstick for average RTP as possible!

The range of bets on the site we tested ran from a minimum bet per spin of $/£/€0.10 up to a maximum of $/£/€100.00 per spin.

Rio Mystery Night is a low volatility slot, making it a poor match for our preferred slot machine strategies. Our slot strategies target the highest possible volatility, so Rio Mystery Night is excluded based on this criterion alone.

This gamble feature offers a way of increasing the volatility of this slot in a way that is in the player's full control.

Conclusion

While we like the style and theme of Rio Mystery Night, this slot is let down by merely average RTP combined with low volatility.

Players who are not worried about volatility will find much to enjoy in this relatively simple and vibrantly themed slot.
