Beta Launch (January 22, 2026)

Slime Seas entered closed beta on January 22, 2026. All beta participants received the Beta Player badge. First promo codes (HUBISLAND, SLIMEPIECE, FREEBOOSTS) appeared within the opening week. Full four-zone progression from Starter Island through Sovereign's End was available at launch alongside guilds, trading, and PvP.

Official experience created October 31, 2025 by Slime Slaying Online (creator Chris Burton). Track live data on official Trello and verify codes on active codes before each session.

Upcoming Content — Dungeons

Dungeon content has been teased since early 2026 via promo codes (DJINNDUNGEON, DUNGEONKEYSUPDATE, DUNGEONDELAYEDSORRY compensation bundles) but remains unreleased as of July 2026. The Rebirths update suggests end-game expansion is the current development priority before standalone dungeon instances ship.

When dungeon content launches, expect new codes, Trello cards, and wiki pages within 24–48 hours. Bookmark this update log and the events page for first notice.
