Sky of Thunder

  • 2.5/5


Off to ancient times! Let yourself be whisked away to the magic world of Greek mythology and travel to Olympus with the mighty god Zeus where divine winning chances await you. Climb into the saddle of Pegasus when he spreads his wings and rides through the clouds: an amazing, fantastic adventure awaits you!


Travel back in time to antiquity with Sky of Thunder and immerse into the world of Greek gods and mythical creatures. Meet Zeus, the ruler of Olympus, and his winged horse Pegasus that gallops across 40 pay lines to gold and riches with you in the saddle!


Your aim with Sky of Thunder is to land five identical winning symbols from left to right on the reels. There are 40 win lines.

Bonus symbols

Alms plate, amphora, griffin and Pegasus are not only single symbols but also appear as double symbols on the reels. In this case they are marked with a small "x 2" in the lower right corner. Such a double symbol counts as two identical single symbols. If a double symbol is substituted by a Wild symbol it also counts as two single symbols on the pay line.

The oak leaf is the Wild symbol with Sky of Thunder. It substitutes for all symbols except the Bonus symbol.



If the Zeus symbols (Bonus symbol) lands in all four positions of the first reel the Free-Spins-Bonus-Game is triggered. Here, all other Zeus symbols on the remaining reels are held in their positions and an automatic spin of reels two and five is triggered. If further Zeus symbols land as a result they are also held and another spin is triggered. This process is repeated until no more Zeus symbols appear or all positions show Zeus symbols. If all positions of all reels show Zeus symbols, you’ll win 15 free spins.


Four matching symbols on the first reel during the free games (Pegasus, griffin, bull, alms plate or amphora as a single or double symbol) trigger the Lock-&-Spin-Bonus-Feature. If for example the Pegasus symbol lands four times on the first reel, the Pegasus symbols on the remaining reels as well as all Wild symbols are also held in their positions and the reels spin again automatically. If more Pegasus or Wild symbols appear during this spin these are also held in their positions and another spin is triggered. This process is repeated until no more Pegasus or Wild symbols appear or all reels show Pegasus or Wild symbols.
