3 Scattered Bonus-symbols triggers the Zeus 2 bonus of 10 free games. Zeus 2 has 5 reels, 4 rows and 50 fixed paylines. If a full stack with Zeus symbols appears on the first reel, you have won the Hot Hot Respin feature. You will get 2 Hot Hot Respins, where all Zeus and wild symbols are held. The goal is to add as many Zeus symbols and wilds as possible, hopefully with a full screen of Zeus symbols as a result. This gives you 7,500 coins.
3 scattered lightning bolts on reels 1, 3 and 5 gives you the free spins bonus game. You will receive 10 free spins, with extra Zeus and extra wild symbols placed on the reels. It is possible to retrigger the free spins.
