Temple of Thunder II Slot by Evoplay

The original Temple of Thunder ran on synced reels and nothing else - no free spins, no bonus round, just identical reel strips expanding across a 243-ways grid. This sequel scraps that system. In its place: Mystery symbols that reveal Wilds, regular symbols, or Coins, plus a Hold&Win bonus and a proper free spins round. A fundamentally different game wearing the same Greek mythology skin.

Five or more Coins from Mystery reveals on a single spin trigger Hold&Win with 3 respins. New Coins reset the counter. The four fixed prizes - Mini, Minor, Major, and Epic - sit on the left side of the grid against a bright blue sky and rolling green hills, and individual coin multipliers range from 1x up to 25x per position. Fill every spot on the 5x3 grid and the Epic prize at 3,000x stacks on top of all collected values. A Bonus Buy version exists for skipping straight to free spins, but this base version locks both features behind natural triggers. Free spins award 10 rounds from three scatters on the middle reels, with retriggers available.

The split between modes matters more than it looks. During free spins, Mystery symbols stop producing Coins entirely. No Hold&Win trigger is possible inside the bonus round. It runs purely on payline wins and Wild substitutions - a hard wall between the two features rather than the layered stacking most Hold&Win slots use. The goddess portrait and purple-toned card royals (K, Q, J, A in cool blue and green) give it a brighter, more saturated palette than the stormy original, but the math changed more than the art did. Two separate win paths that never overlap.
