Olympus Thunder is a 5 reel, 20 payline slot from NextGen Gaming that can be played on all devices from 20p to £100 per spin. With a Greek mythology theme, it offers you 3 re-spins with an expanding wild Zeus on the middle reel as well as an Olympus Bonus feature where you can get up to 40 free spins with a 3x multiplier.

Visually, Olympus Thunder looks fantastic – much like NextGen Gaming’s Renegades slot, the cartoon style graphics are superb. With Mount Olympus in the backdrop, symbols on the reels include Greek style A, K, Q, J, 10 and 9 playing cards as well as vases and harps. You will also see Aphrodite (the Goddess of beauty and love), Pan (the God of the wild, shepherds and flocks) and Zeus (the King of the Gods and ruler of Mount Olympus).

Zeus is the wild symbol and substitutes for all symbols except the bonus scatter – it’s also the most valuable symbol as 2, 3, 4 or 5 on a payline will give you 0.5, 10, 100 or 500 times your stake respectively. That’s pretty good value for a wild symbol!

In terms of bonus features, Olympus Thunder comes with 2. First up is the Zeus Re-Spins feature – this is triggered when the Zeus wild appears on the middle reel. You will then be rewarded with 3 re-spins – the Zeus wild then expands on the middle reel and remains in position throughout the re-spins.

Then you have the Olympus Bonus feature which is played when the lightning bolt bonus scatter symbol appears simultaneously on the 3 middle reels. Then you get to pick coins until you find 3 of the same – 1 of the following prizes will be awarded at random:

  • 5 free spins with a 2x multiplier
  • 7 free spins with a 2x multiplier
  • 10 free spins with a 2x multiplier
  • 15 free spins with a 2x multiplier
  • 20 free spins with a 3x multiplier

The good news is that you can retrigger the feature which can potentially reward you with 40 free spins with a 3x multiplier – furthermore, the Zeus Re-Spins feature can also be triggered on each free spin which helps.

Overall, Olympus Thunder is a superb slot and 1 of NextGen Gaming’s better efforts – it looks superb and has the bonus features to match. It’s also highly volatile which maximum wins of 3,000 times your stake on each free spin with a 3x multiplier! If you like the theme, Playtech offers you the Age of the Gods series.
