Developer Petro Fortuna is a 5-reel online slot from Merkur Gaming, released in 2019, with 20 adjustable paylines and a mining setting built around underground caverns, gold nuggets, tools, and treasure chests. Standard symbols include 7, A, K, Q, J, and ten, while the golden pickaxe acts as the Wild and the mining cart serves as the Scatter.
Three or more Scatter symbols trigger the bonus round, awarding up to 15 free spins. During this feature, multipliers can rise from x1 to x10, and Wild symbols appear more often, changing the way winning lines are formed. The game also includes a Quick Spin option, allowing multiple spins to run in succession.
The slot has a stated RTP of about 96% and medium-high volatility, which means results may vary over shorter sessions. Bets range from $0.01 to $100, and the demo version lets players play for free and practice before playing for real money.
