Rio Gems is a slot by 3 Oaks Gaming. The matrix classified it under Pragmatic Play, but the official 3 Oaks page and API confirm the title, the provider, and a release in Dec 2022.
The game sets a Rio carnival on a 5x3 grid with 25 paylines. The core of the official sheet revolves around three ideas: Hold & Win Bonus, Super Bonus Game, and Free Spins. It is therefore a sheet focused on gem collection, fixed jackpots, and bonus symbols.
What 3 Oaks Confirms
Six blue or green Bonus gems trigger the Hold & Win Bonus. The round begins with three respins, and then each new Bonus symbol resets the pressure on the grid. The Mystery Symbol can reveal a jackpot or a Super Bonus Symbol, which gives the bonus its true momentum.

Hold & Win and Super Bonus Game
During Hold & Win, the Bonus symbols remain on the grid, and the round is played around new gems falling. The Super Bonus Game starts with five blue or green Bonus gems and one white Super Symbol gem, then it improves the value of the Bonus Symbols that appear during the feature.
The jackpots listed by 3 Oaks are Mini, Minor, Major, and Grand. If all 15 positions are filled, the Royal Jackpot is announced at x10,000 the bet. This is the official maximum value usable for this sheet.
Mystery Symbols and Free Spins
The Mystery Symbol serves as a point of controlled uncertainty: it can reveal one of the jackpots or a Super Bonus Symbol. If a Super Symbol appears during the Hold & Win Bonus, it immediately triggers the Super Bonus Game.
The Free Spins close the loop with only the highest-paying symbols in play. The official source does not provide all the payout figures, but it clearly shows the role of the bonuses and jackpots.
Point of Attention
The public sheet from 3 Oaks does not publish an RTP, volatility, min/max bet, or exploitable hit frequency for this page. These values are therefore not invented here. Before playing for real money, always check the information screen displayed by the operator.
Another important point: the game source code of the matrix is kept in the CMS for the demo, but it must not be copied into a public report or shared with its technical parameters.
Our Quick Review
Rio Gems is mainly aimed at players who enjoy Hold & Win games with counters, bonus symbols, and fixed jackpots. The official source provides enough material to understand the game, but not enough to judge its payout rate without the casino's help screen.
To stay with 3 Oaks, compare it with Sunlight Princess and Tiger Gems. The slot machines page, the best online casinos, and the online casinos France then allow you to place the game in a broader selection.
