Rio Gems is the 3OAKS carnival slot with the highest RTP among the studio new entries in this catalogue: 95.69% at high volatility and a 10,000x ceiling. Play for real money through the IPU.BET rating: cashback on losses is credited when you register at the casino through the rating.
About the game
A carnival 5x3 on 25 lines, gems instead of the usual Egyptian or Asian set. Three scatters give eight free spins, and the respin bonus on gem symbols is where the ceiling of 10,000x sits; the base game is deliberately quiet between them.

Rio Gems moves 3 Oaks slots away from the usual pyramids and Asian temples to the Brazilian carnival. Feathers, dancers, drums and gemstones fall onto the reels to a samba beat. The game came out at the end of 2022, with a stated RTP of 95.69%, high volatility and a max win of 10,000x the bet. Here is where its main potential lies.
Grid and base game
A 5x3 grid with 25 lines. The base game is deliberately calm: it brings small line payouts and prepares the ground for the bonuses. The wild can appear on any reel and helps complete lines.
Hold and Win with gemstones
Six blue or green gems trigger Hold and Win with three respins. In the round you can land bonus symbols with the Mini, Minor, Major and Grand jackpots, and a mystery symbol reveals one of the jackpots or a super symbol. Filling all positions gives the Royal Jackpot, 10,000x the bet. That is the game's ceiling.
Super Bonus with the white gem
If five blue or green gems land together with the white super symbol, the Super Bonus starts. It works like a regular Hold and Win, but the values of all bonus symbols are increased, with a minimum gem value of 5x the bet. A super symbol that lands during a regular round instantly turns it into a Super Bonus.
Free spins
Separately from the respins, the game has free spins triggered by scatters. In this mode only the highest paying symbols remain on the reels, so line payouts become noticeably heavier.
Who it suits
Rio Gems suits players who value the hold mechanic and are prepared to wait a long time for a full grid. With high volatility, long runs without a bonus are normal, so try the demo first and set a session budget.
