Sigma Isles

Survival with server-side mods you don't need to install, voice chat, jobs, a battle pass and a mini-game hub.

Sigma Isles is a survival server with server-side mods. Join with a regular Minecraft 26.3 client: you don't need Fabric, a modpack or a launcher. The server offers an optional resource pack that makes modded items and blocks look right. Non-premium players are welcome. Register with an in-game command the first time you join.

Survival
- A large pre-generated world with Terralith terrain, so exploring stays smooth
- Farmer's Delight and Friends & Foes content, with no client install
- Random teleport, homes and waystones to get around
- /compass finds the nearest biome or structure in your current dimension and points a compass at it

Land claims
Buy a claim block in the private shop and place it to protect your base from sky to bedrock. There are four sizes, from 17x17 up to 129x129. You can own up to 5 claims, give them names, and trust friends on one claim or all of them. A glowing border shows exactly where each claim ends.

Economy
- New players start with $15,000 and can collect $2,000 every day
- Server shop, player auction house, buy orders and payments between players
- Dying costs 2% of your balance, so keep an eye on your risks

Progress
- Jobs: Miner, Lumberjack, Farmer, Hunter or Fisher. Pick one, level up to 50 and earn more as you grow
- Battle pass: 30-day seasons with 30 levels and a free reward track
- Daily streak: rewards grow the longer you keep logging in, with bigger prizes every 7 and 30 days
- Playtime titles: active time unlocks money and a title you can show in chat
- Referrals: invite a friend and you both get a reward once they have played for 2 hours

The hub
Everyone arrives at a floating sakura island with a town full of things to do:
- Spleef, parkour and a maze
- An auto mine with a shop, a drift track and a meteor arena
- A colosseum that hosts PvP tournaments with a provided kit
- Spawn auras and join animations you can buy with in-game money

Voice chat
Proximity voice chat works with the optional Simple Voice Chat mod, which needs a Fabric client. Everything else works without it.

Ranks
Optional paid ranks (VIP, Premium, Legend) are available for 30 days at a time. They add kits and a wider random teleport radius, among other perks.
