The game is set in clouds with mountains as the background. The symbols on the reels are low-value cards A, Q, J, and 10, as well as god Zeus, goddess Athena and goddess Aphrodite, and amphorae. Hades is the most lucrative symbol - five of these symbols on a payline will bring you 50 times your stake. The wild symbol is also the golden coin. This substitutes for all symbols, except the scatters.
Persephone is the first scatter - landing 3 or more anywhere on the reels triggers the Free Spins feature, which will give you 8 free spins. As these coins are added to the reels, a multiplier of 1 to 10x will be applied to each one. There are also ways to win more free spins. 3 scatters give you 4 extra spins, while 4 scatters give you 8 more.
Hades is the second scatter - three of these symbols on the reels will activate the Gates of Olympus Bonus game. The next step is to select from 12 coins that will reveal either a cash prize, or a key. Each key you collect advances you to the next level, with greater prizes. There are five levels total, with cash prizes that range from two times your stake to 400 times your stake.
