Rise of Olympus is a Greek-mythology-themed slot from Play’n GO, released in 2018 and built around Zeus, Poseidon and Hades. It uses a 5×5 grid with cluster pays rather than traditional paylines.
Landing a cluster win of 5+ matching symbols triggers a re-spin with the winning symbols removed and new ones tumbling in; every 5th consecutive win during a hot streak upgrades the lowest-paying active symbol to the next tier up, letting values escalate quickly during a good run without a separate free-spins trigger required.
Rise of Olympus runs a 96.5% RTP at its default setting (some published operator configurations run as low as 84.50%, a wider-than-usual spread we flag for verification at review time), high volatility, and a maximum win of 5,000x the stake. Its symbol-upgrade cascade mechanic distinguished it from Play’n GO’s other cluster-pays titles and it remains a frequently cited genre reference for “upgrading symbol” slots.
The demo is free with no download. For real-money play, use a licensed operator for your country and check the specific RTP tier configured — Rise of Olympus has an unusually wide range of published RTP settings across operators.
