What is CubeRealm.io?
CubeRealm.io is a multiplayer block-building game that runs in your browser. Its first-person voxel world lets you explore, collect materials, and shape a place of your own. The mode you choose changes how much of your time goes toward staying alive or constructing something.
Choose the world that suits you
The game menu offers Peaceful, Survival, and Creative. Peaceful describes health regeneration and optional PvP; Survival puts you in an open world with PvP; Creative is aimed at building freely. Choose from the live menu rather than assuming every world follows the same combat rules.
How to play CubeRealm.io
- Open the game and pick Peaceful, Survival, or Creative from the mode menu.
- Once the world loads, check the in-game controls and practice moving and looking around near your starting point.
- In a survival mode, gather nearby materials and inspect the available inventory and crafting options before exploring farther.
- Start a small build, then expand it as you learn block placement and the world's rules.
Start with a manageable build
Use a simple plan: small footprint → walls → usable entrance → expansion. A compact first project makes it easier to learn placement and see what materials you still need. Pick Creative if construction is your main interest; try Peaceful before entering a PvP survival world.
