As a result, the reels will start spinning and symbols will randomly appear on them according to the pay table. The game aims at collecting winning combinations of three symbols on the active paylines to trigger a reward.

  1. If a winning combination occurs, you will receive a payout according to your stake and the corresponding values of the symbols, as indicated in the payout table
  2. You can also activate the autoplay and turbo mode option next to the spin button to trigger automatic spins or reel acceleration

Rio Gems has 5 bright reels and 3 rows. You will have the opportunity to form your winnings thanks to 25 paylines. As for gaming bets, the minimum is €0.25, and the maximum is €20, so fans of big bets may not be very comfortable here.

Rio Gems RTP and Volatility


The slot has an RTP coefficient of 95.69% and fairly high volatility.

Rio Gems has a relatively small RTP, which gives players an idea of what percentage of the money staked will eventually be returned. A higher RTP means that more money is returned to players in the form of winnings. The game also has fairly high volatility, which means that your winnings can fluctuate greatly over short periods.

Typically, games with high volatility offer potentially big winnings, but they can also bring big losses if you're not careful. Rio Gems is therefore ideal for experienced players who like to take risks and don't mind walking away with small wins or big losses, depending on their luck that day.


The Rio Gems theme is based on bright colors and cheerful tropical drawings that are sure to bring the energy of Rio de Janeiro right into your home! Vivid visuals are combined with live sound effects, including traditional Brazilian music, which gives the game authenticity and immerses you in its energetic atmosphere. The graphics are crisp and clear, making it easy for players to keep track of winnings and bonuses during each spin. With its vibrant atmosphere, stunning visuals and unbeatable bonus features, this slot promises hours of endless fun.

These colorful reels will offer you quite interesting symbols, including a wild symbol that can pay from 0.8x to 12x bet per line. As well as a scatter symbol with a multiplier of 2x bet per line.

There are also mysterious symbols that appear randomly in the bonus game and turn into Diamond Jackpot or Super Diamond symbols.

Four symbols in the form of beautiful samba dancers will bring you from 0.2x to 10x bet per line.

The symbols with the lowest payouts are A, K, Q and J, which can bring from 0.2x to 2x bet per line.
