Parthenon: Quest for Immortality™ by NetEnt is a 6-reel video slot set in Ancient Greek mythology. The game uses a 10,000 bet ways format, where wins are formed on adjacent reels from left to right rather than on fixed paylines. A demo version is available for players who want to play for free and practice before playing for real money.
The main features include Avalanche mechanics, where winning symbols disappear and new ones fall into place, and a Wild Generation Zone on the top row. Symbols in that zone can transform into Wilds after a win is checked, then remain on the grid for the next cascade. The slot also includes Free Spins, triggered by three Free Spins symbols, with extra spins awarded for additional scatters during the feature.
During Free Spins, a progressive multiplier starts at x1 and can rise to x20 each time a symbol turns into a Wild. The symbol set includes Medusa, Pegasus, tridents, ships, and card-rank icons, while the overall presentation uses marble, gold, and temple imagery. The stated RTP is 96.03%, with high volatility and a bet range from 0.2 to 200.
