The age of God looks great - the symbols on the scroll include all the gods mentioned above. Athena is the symbol of the highest value (the gods), rewarding you to bet 5 on the payline with a 5x line.
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.
