About Rio Gems
Rio Gems is pure party, with sparkling gems and bright plumes landing on 5 × 3 reels and 25 lines to a Brazilian beat. Watch the colored Gems most closely: blue and green ones build the bonus, and a white one changes what it's worth.
Inside Rio Gems
Blue and Green Gem respins
Six Blue or Green Gem Bonus Symbols start the Hold & Win Bonus with three respins, and each new Gem resets them. Bonus Symbols can carry the Mini, Minor, Major and Grand jackpots, and a Mystery Symbol may reveal one or a Super Bonus Symbol.
The White Gem Super Bonus
Five Blue or Green Gems landing with a White Gem Super Symbol start the Super Bonus Game. It plays like the regular bonus, but every Bonus Symbol that appears gets a boost to its value.
Free spins for the headliners
Three drum Scatters start 8 Free Spins, and three more during the round add another 8. Only the top-paying symbols are in play, so every spin of it draws from the reels' highest payers.
Rio Gems questions
What if a White Gem lands mid-bonus?
A Super Symbol landing during the regular Hold & Win round switches you straight into the Super Bonus Game, boosted values and all.
Is there a prize for a full screen?
Yes. Filling every reel position during the bonus can potentially award the Royal Jackpot, a fifth tier above the Grand.
Where can the feathery Wild land?
It can turn up on any of the five reels, standing in for every regular symbol to help a line come together.
