Temple of Thunder III Slot by Evoplay

Third entry in the Temple of Thunder series, and the first one to bolt a Hold & Win Bonus and a 5-tier jackpot ladder onto what used to be a straightforward Free Spins slot. The 2022 original and the January 2024 sequel both worked the Zeus angle with scatters and free games only. This one keeps the storm-king setting but rebuilds the bonus economy around sticky symbols.

The Hold & Win triggers when 6 or more Bonus or Booster symbols land on the same spin. From there you get 3 respins, only Bonus and Booster symbols can appear, and every new Bonus that lands resets the respin counter back to 3. Bonuses stick. Boosters do not. The round closes when respins hit zero or when all 15 positions fill, in which case the entire Bonus payout is doubled. Cash symbols carry values from x0.2 up to x6 of your bet, except each one is hard-capped at x200 - any Booster overflow above that cap is lost, which matters because a Super Cash Booster doubles every Cash value on the grid in one hit.

The five jackpots sit above the reels: Mini, Minor, Major, Mega, Grand, paying 10x, 25x, 50x, 100x and 200x your bet. Jackpot Boosters bump symbols up one tier, except Grand, which they cannot touch. Free Spins still exist and still come from 3, 4 or 5 scatters for 10, 12 or 15 spins, and the Hold & Win can also fire inside the bonus round. Retriggers during Free Spins add 5, 7 or 10 extra spins.

For impatient players, four Buy Bonus options sit in the menu. Hold & Win directly is the priciest at 97x your bet, while the three Free Spins entry points run 52x, 64x and 77x for the 10, 12 and 15-spin versions. There's also a Bonus Chance ante at 1.8x stake that roughly doubles scatter frequency, and a heavier Super Booster at 5x stake for around 5x the trigger rate. Wins still pay from your base bet on those modes, not the inflated cost.

Visually Evoplay hasn't strayed from the series template. A blue-bearded Zeus glares down from above the grid, ruined Greek columns sit in the background, lightning streaks across a stormy sky. Greek meander patterns trace the ornate stone border around the reels, and the jackpot bars across the top use the standard colored Mini-to-Grand ladder. The Wild is a cyan disc with a Greek key motif, the Cash symbol is a golden lyre with a multiplier stamped on it, and gemstones and crowns fill out the lower paytable. It's the same Mount Olympus the first two games used, just with more machinery underneath.
