The mighty Zeus can show up at any point to offer a Power Spin with one of 5 modifiers: Bonus Thunder (adds Bonus symbols to increase the chance of triggering the bonus round), Wild Thunder (adds multiplying Wilds), Colossal Thunder (up to 6 reels transformed into colossal reels), Mystery Thunder (Mystery symbols added to all reels) or Respin Thunder (winning symbols held while other positions re-spin).

It takes 3 Scatters to win 10 Free Spins while 4, 5 and 6 award 12, 15 and 20 spins respectively. Triggering the Bonus round also awards Bonus Thunder and prompts the player to pick one of four artefacts. Wild Storm Free Spins activate special Thunderbolt overlays on reels 1 and 6, allowing for overlays to turn the corresponding symbols on reels 2-5 into Wilds. Landing 3 Scatters increases the number of Megaways and wins the player additional 2 spins.

If one picks Rise Of Olympia Free Spins, they’ll benefit from an unlimited win multiplier applied to all bonus round wins. Every Wild icon which lands on reels 2-5 increases the multiplier by 1 and accumulating Wilds in increments of 5 adds 2 free games to those already won. During Colossal Free Spins, x2 roaming Wilds become active; having stopped, they will turn the corresponding reel positions into substitutes.

Accumulating 3 Scatters upgrades roaming Wilds (up to x625!) and gets you 2 more spins on the house. Almighty Wild Free Spins begin with Wild multipliers of x2 and x3 which will get upgraded by a Scatter trio and potentially boost your payouts by as much as x625. Scatters will also award 2 extra spins.

Scatter symbols can be elusive but there are a couple of alternative options. Power Spins Bonus Bet costs 50x the player’s stake, and if you’re willing to pay the price, Zeus Power Spins will trigger automatically. Bonus Guarantee Bet, which costs 100x the stake, triggers 3+ Bonus symbols, grants access into Bonus Thunder and offers 4 artefacts to choose from.
