Pet Simulator 99 egg expected value checker

What is one hatch worth on average? For each egg below, the expected value is the sum over its hatch list of (published chance x current Normal RAP), from the official feed pulled November 1, 2026, 16:42 UTC. Only 125 of 551 eggs qualify: the rest either keep some hatch chances unpublished or contain a pet with no recorded Normal RAP, and an expected value built on a guess would be a made up number, so they are left out on purpose.

An average over many hatches, not a promise for one egg: most hatches return the common pets and the average is carried by the rare ones. Egg prices are in game coins or event currency, not diamonds, so this checker gives you the diamond value of what comes out, not a buy or sell verdict on the egg itself.

Values and exists counts: the official BIG Games public API (ps99.biggamesapi.io), pulled November 1, 2026, 16:42 UTC. RAP is a recorded average of real Trading Plaza and auction sales, not a guaranteed trade price.
