Behind the scenes at Hylterium
Panels that no longer step on each other, open when they help you and fold with a double Ctrl, a bar for your wealth, and quests that show you the way: here is Hylterium's new interface.

Hylterium is a French-speaking Hytale community with two game modes: an MMORPG at the Castle and Skyblock on the Floating Isles. Choose between guild progression and dungeon exploration, or developing your island and completing challenges.
Launch Hytale, add this server address to your list, then connect: play.hylterium.com. You do not need to create an account on this website to join the server.
The Castle offers professions, guilds, dungeons and a player economy. The Floating Isles offer Skyblock progression with generators, challenges and leaderboards. You can explore both modes on Hylterium.
Yes, Hylterium is free. The store is optional: XP, profession and reputation boosts, Hyltgems for cosmetics, community events and, on Skyblock, ranks. Voting for the server also earns in-game rewards.
No. There is no mod to install: all you need is Hytale and the server address.
Yes: you need a copy of Hytale, the game by Hypixel Studios available on hytale.com, kept up to date, since after an update the server only accepts the new version. Hylterium itself is free, with no mod to install and no account to create on this website.
No. Hylterium has been open to the public since 13 January 2026, and its Skyblock since 4 July 2026. The server follows Hytale's updates: it has run Update 7 since 13 October 2026.
Hylterium has run Hytale Update 7 since 13 October 2026, on both its MMORPG and Skyblock servers.
The Hylterium community has existed since June 2025. Its MMORPG world, the Castle, was joined by the Floating Isles Skyblock on 4 July 2026.
Yes. In the MMORPG you found a guild that levels through 25 tiers and run dungeons as a group. In Skyblock you invite friends to your island and give them roles.
On the Hylterium Discord, where the team answers in French, and on the site's Bugs page, which tracks every report.
Voting puts Hylterium on the map and earns you in-game rewards. The store funds the servers directly.
