Pet Simulator 99 update log

The official log lists 100 updates. Update 1 is 9 Dec 2023. Update 100, Halloween Games, is 31 Oct 2026. The year split on that page is 28 in 2026 (73 through 100), 32 in 2025, 36 in 2024 and 4 in 2023. The cadence on the next-update page is every Saturday at 11:00 AM Central.

Recent titles, in order: 100 Halloween Games, 99 PSX Classic, 98 Diamond Mountain, 97 Blood Moon, 96 Hatch Wars, 95 Space Forge, 94 Space Mine. I am not pasting each blog post. The table links the official note. What it means for you is on the event pages and the next-update page.

Read an old update without mixing it into the current patch

Start with the update number and publication date. A new zone, egg or item can remain in the database after its launch event changes. The announcement explains what was introduced; the current event note determines whether a limited activity is being promoted now. Keep release dates separate from contest durations, claim windows and trade unlocks. A weekly Saturday cadence alone does not establish any of those closing times.

Use the archive for the full numbered history, the event pages for mechanics such as Blood Moon and the Forge, and the next-update page for time zones. This index is a list of source announcements. It does not rename an old mechanic as a new feature merely because the same pet appears in a later image.
