The game screen is fairly standard with five reels featuring three symbols. It has to happen on 15 paylines. If you spin a winning combination on at least one of those paylines, you win a prize. The price depends on which combination you spin and your bet. Speaking of wagering: you can bet from € 0.15 per spin up to and including € 15 per spin. In other words, € 0.01 per payline up to a maximum of € 1 per payline.
As is often the case on Microgaming slots, the symbol with the logo of the slot machine on it is the Wild symbol. The Titans of the Sun symbol is Wild and pays out up to 500 times the stake per payline. And no other symbol on the Titans of the Sun Hyperion slot machine can match that.
Hyperion, including Gordon haircut, is good for up to 200 times the stake. Furthermore, the magical horse Pegasis and the Phoenix also participate in Titans of the Sun Hyperion. Five playing card symbols yield smaller payouts of up to 100 times the stake.
The feature in the base game is the Stacked Mystery Symbols feature. There are suns on the reels. Stacked, that is, grouped, so that you sometimes get several on your screen at the same time. These suns change into one other symbol. Which symbol? That's a surprise every time.

A romantic picture of the loving brother-sister couple Theia and Hyperion is the symbol that triggers the Titans of the Sun Hyperion bonus. That is, if you have at least three of them on your screen.
You will then receive 15 bonus spins. During these bonus spins you will unlock 15 extra spins every time you spin at least three times the bonus symbol.
Furthermore, the bonus game works exactly the same as the basic game.
