Carnival fever is in full swing with Rio Gems, a dazzling 5x3, 25-line slot by 3 Oaks!
The party comes to life on reels flooded with bright feathers, gorgeous female dancers, Brazilian drums and sparkling gems, all landing on the screen in the rhythm of samba. The game’s highlights are the HOLD & WIN BONUS and FREE SPINS. The carnival vibe reaches new heights with the chance to win JACKPOT prizes!
FEATURES
Central to this thrilling celebration, the HOLD & WIN BONUS kicks off when six Blue or Green Gem BONUS SYMBOLS land on the reels, granting three respins. During this feature, players have the chance to land BONUS SYMBOLS with MINI, MINOR, MAJOR and GRAND JACKPOTS. Also, the MYSTERY SYMBOL has the potential to land, revealing one of these JACKPOTS or a SUPER BONUS SYMBOL. Filling all reel positions may potentially result in the ROYAL JACKPOT prize of x10,000 the bet.
But the party doesn’t stop there! The SUPER BONUS GAME begins when five Blue or Green BONUS SYMBOLS appear alongside a White Gem SUPER SYMBOL. This round plays out just like the regular HOLD & WIN BONUS but with a twist— it boosts the value of all BONUS SYMBOLS appearing during the feature. If a SUPER SYMBOL lands during the HOLD & WIN BONUS round, it instantly triggers the SUPER BONUS GAME.
To add even more excitement and winning potential, the game offers FREE SPINS with only top-paying symbols in play.
With stunning visuals and infectious carnival music, Rio Gems delivers a top-tier gaming experience full of colour, energy and exciting gameplay!
