The Heart of Rio slot game has an adjustable RTP between an extremely low 90.02% to an average 96.50%. Low return rates mean that you are far less likely to score payouts, while average rates indicate that the game doesn’t quite have that edge over you. The Heart of Rio slot online has a standard volatility, so pairing that with the average RTP is a pretty solid choice that could reward you with some decent prizes. The Heart of Rio online slot’s grid is positively bursting with festive colours, from the low-value traditional card symbols to the more coveted symbols that feature the wide variety of dancers taking part in the carnival. The dancer with the purple costume pays out the highest at 32x for a combination of five identical symbols. The dancer with the red headdress is the wild symbol, which functions as a substitute for missing symbols needed to form a winning line and trigger a payout. It doesn’t work on any bonus symbols and appears on all reels except the leftmost. The drums are the scatter symbol, appearing only in the middle reels and operating as both a symbol for additional payouts as well as a trigger to activate the free spins. There is also an exciting money symbol in the Heart of Rio slot machine, which could trigger some random modifiers throughout the main game. These include symbol values being added together, values being multiplied, symbols themselves turning into stacks for even more payouts, and even respins. If you enjoy party themes and slots with plenty of bonus features, this one is hard to beat.
