About this Slot
Thunder Dog is a Greek Mythology slot from ROOFTOP GAMING with an RTP of 96.63%, high volatility and a maximum win of 15,000x.
The game uses cluster pays, where winning groups of matching symbols pay across the reels. Cascading reels drop winning symbols away to allow new symbols to fall into place. A wild symbol substitutes for other symbols to complete clusters.
Thunder Strike appears randomly during the base game, Free Spins and Super Free Spins, adding multipliers of 2x to 1,000x to winning clusters. The Thunder Cloud feature lands between 1 and 5 clouds on each spin, with each cloud containing matching symbols to create additional cluster-forming opportunities.
Four Bonus symbols trigger 15 Free Spins. During Free Spins, multiplier symbols accumulate and apply their values to subsequent winning clusters. Three Bonus symbols landing during the Free Spins round retrigger 5 additional spins.
Five Bonus symbols trigger 15 Super Free Spins instead. In Super Free Spins, Random Extra Prizes worth 1x to 50x the bet can land, collecting only when their attached symbols form a winning cluster.
Free Spins end when the 15,000x maximum win is reached. A Bonus Buy menu provides direct access to all bonus features.
