Thunder of Olympus

Thunder of Olympus by Booongo is a Greek-mythology slot released in September 2020. The game uses a 3x5 reel layout with 25 paylines and a Hold and Win structure. Its symbol set includes character icons, card values, a Wild urn, Scatter symbols, and a Bonus symbol linked to collection-style features. The demo version lets players play for free and practice before playing for real money.

The main bonus round starts when at least six ball lightning Bonus symbols appear, triggering respins in which collected symbols remain fixed and new ones can add further wins. Landing three Scatter symbols starts free spins, with only high-paying symbols in the reel set during the feature. Free spins may retrigger, and the bonus game can continue until all 15 bonus positions are filled or respins run out.

The slot also includes a Grand Jackpot worth up to 1,000x the bet, alongside Mini and Major jackpot values shown in the interface. Visuals follow a Mount Olympus theme, with lightning effects, classical Greek imagery, and themed portrait symbols. The review page and demo launcher provide a way to inspect the paytable, bonus rules, and feature mechanics before choosing to play for real money.
