Evoplay is heading back to Mount Olympus with Temple of Thunder III, the latest entry in its mythology-fuelled slot series, and this one looks to be packing more than a few bolts from the big man himself.
Set against a divine backdrop, the 5×3 slot sees Zeus obviously take center stage as the premium symbol, joined by golden crowns, harps, ancient treasures, and other suitably godly icons.
As you can see, it’s very much leaning into that grand Greek mythology aesthetic, but the gaming pull is in the feature set, with Hold & Win mechanics, Boosters, Free Spins, and jackpot upgrades all rolled into one package.
Hold & Win sits at the heart of the action
The main event is the Hold & Win bonus, which triggers when six or more Cash, Jackpot, or Booster symbols land anywhere on the reels. Once activated, those Bonus symbols lock into place, and you’ll receive three respins, with every new symbol resetting the counter back to three.
Cash symbols award instant prizes during the feature, while the five fixed jackpots of Mini, Minor, Major, Mega, and Grand can also appear, giving you multiple prize tiers to chase.
Where things start to get a little spicier is through the Booster symbols. Cash Boosters increase all visible Cash values by 50%, while Super Cash Boosters double them entirely. Jackpot Boosters, meanwhile, upgrade any visible Jackpot symbols to the next tier, which can make a promising round look far more interesting.
Full Grid feature and Free Spins add something extra
If you manage to fill the entire grid with Bonus symbols during Hold & Win, the Full Grid 2x feature kicks in, doubling all collected rewards before the round comes to an end. It’s a nice endgame-style mechanic that gives the bonus round a clear chase.
There’s also a Free Spins mode, triggered by landing three or more Scatters. During this feature, Zeus appears more often, Wilds become more impactful, and the chances of triggering Hold & Win are increased. Additional Free Spins can also be retriggered, giving the round a little more room to breathe if the reels are playing nicely.
For those of you who want to skip straight to the fireworks, Temple of Thunder III also includes a Bonus Buy option, offering direct access to Hold & Win or bundles of 10, 12, or 15 Free Spins.
