Olympus Glory is the three-card Greek table on the PH77 cards shelf - you and the god-tier dealer each draw three cards, the stronger poker hand takes the round, and a pair-plus side line pays by hand strength no matter who wins the deal.
The direct answer: post the Ante, read your three cards, and Play whenever the hand reaches queen-high or better - that single decision rule is the whole PH77 Olympus Glory method, and an Olympus Glory demo block drills it before the first funded deal.
