Island by island

The chests are your starting point

The Overworld is made of small islands with different themes. Below them is only void. Each island has two chests you can reach. The starting island provides wood, dirt, saplings, water and lava for farms and a cobblestone generator.

Other islands have more supplies and random extra items. The Nether and End stay normal. To reach the End, find the empty portal altar: an End portal without any Eyes of Ender inserted. Craft the eyes yourself, which also means visiting the Nether.

World generation decides which islands you find next.

Example round: you use starter supplies to build a safe bridge. The next island might have useful materials for a tool; there is no fixed first exploration island.

Tips for Chest Skyblock

Bring enough blocks for the next bridge. Keep the supplies you need for your farms.

01Share starter supplies
Save saplings, seeds and water for renewable farms instead of using everything at once.
02Make bridges safer
Build a railing or a wider bridge so you are less likely to fall while carrying items.
03Remember the portal altar
Note the coordinates when you find a portal altar. Eyes of Ender point to normal strongholds, not this altar.

Another twist

Chest Skyblock FAQ

What to know before building your first bridge.

Do I start with tools or Eyes of Ender?

No. Starter chests contain basic bridge and farm supplies, but no tools, Eyes of Ender, iron ingots or obsidian.

How do I find the End portal?

Explore the island world and look for an empty portal altar. Craft twelve Eyes of Ender and place them in its frames.

Are the Nether and End island worlds too?

No. The special island world replaces only the Overworld; Nether and End terrain remain normal.
