Rio Gems by 3 Oaks Gaming is a vibrant, carnival-themed online slot inspired by the colorful festivities of Rio de Janeiro. Featuring energetic visuals, samba-inspired music, and feature-rich mechanics, the game combines traditional slot gameplay with the popular Hold and Win bonus system and fixed jackpots.
The slot is played on a 5-reel, 3-row layout with 25 active ways to form winning combinations. The reels are filled with lively symbols such as carnival dancers, exotic birds, maracas, and sparkling gemstones. Wild symbols substitute for all regular symbols to help complete combinations, while Scatter and Bonus symbols trigger the game’s main features.
The highlight of the game is the Hold and Win Bonus, triggered by landing six or more Bonus symbols in a single spin. Players receive three respins, which reset with each new Bonus symbol that lands. The feature continues until the respins run out or all reel positions are filled. Bonus symbols reveal instant cash prizes or fixed jackpot values. Players can unlock Mini, Minor, Major, or the Grand jackpot by landing special symbols during the bonus.
In addition, landing three Scatter symbols activates the Free Spins Bonus, awarding a set number of spins during which higher-value symbols dominate the reels, increasing the potential for more valuable outcomes.
Rio Gems features medium to high volatility and a return to player (RTP) of 95.66%, offering an engaging mix of free spins, jackpot rewards, and high-energy gameplay in a festive setting.
