Main Game Features

Wild Ginga Random Wilds

Every so often, a random wilds feature will trigger over any number of the reels before the reels stop. During that time, it will leave a random track of 1 to 20 wilds behind it over the reels. The random wild will replace any symbol except the bonus symbol to create a winning line.

Bonus Wheel Features

Three or more Bonus symbols anywhere on the game reels will trigger the ‘Rio Fever Bonus Wheel’ feature. This feature can have one of the following three outcomes:

Bonus Multipliers – If the wheel lands on one of the six possible ‘Bonus Multipliers’, the ‘Bet’ amount will be multiplied by this number.
‘Samba Parade’ free games mini game.
‘Wild Ginga’ free games mini game.

Samba Parade

In this mini game, you will be awarded with 7 free games. During the game play, starting from the second spin, a sticky wild symbol will randomly be added to one of the reels and will remain there for the entire duration of the mini game. The bonus symbol will not be available during the mini game.

Wild Ginga

The player is awarded with 3 Free Games. On each spin, carnival trumpets will fill up to 5 full reels with Wild symbols, which will remain active for the same spin.
