It has the God of the Gods Bonus feature, which is triggered by getting 3 or more God of the Gods symbols anywhere on the reel (in the base game). 20 God's Era coins appear on the wall - when you match a specific God's 3, you will play the corresponding free spin function. Of all the features, you'll start with 9 free spins, but each has its own characteristics.
The Athena Free Game feature offers you 9 Athena free spins. Before each free spin, Athena gives you a random multiplier between 2x and 5x for the next free spin. Unfortunately, more free spins can't be retriggered. The Zeus free game feature gives you 9 Zeus free spins, starting at 1x multiplier. After every 3 free spins, Zeus increases the multiplier by 1 means that a free spin of 4 to 6 will be affected by a 2x multiplier, while a free spin of 7 to 9 will be affected by a 3x multiplier. In addition, the wild symbol is locked in the middle of the middle reel to help boost your bonus. Finally, there is no way to re-trigger additional free spins.
