Before you start

Before entering the world, take a moment to look at the controls, because Vectaria.io uses more keys than most browser games. Opening the in-game guide with I is the quickest introduction. It also helps to decide what kind of session you want: building on your own, or joining PvP battles. Since the world is shared and online, other players will be around, and the chat is open. If you are playing with a child, it is worth talking about chatting with strangers first, and reading the developer’s privacy policy linked from the game’s page.

How it plays

Vectaria.io opens a world made of blocks that you share with other players online. You can dig into it, collect resources and place blocks to build whatever you like.

Resources lead to crafting. What you gather is turned into items and tools, which in turn let you gather and build more. An inventory, a shop and an in-game guide are each a key away.

The game offers two broad ways to play. You can take part in PvP battles against other players, or ignore fighting and use the world for building and creativity.

Because it is online, the world is shared. Other players may be building, exploring or fighting nearby, and there is a chat for talking to them.

Tips for a first session

  1. Open the in-game guide with I before starting; it explains the basics faster than trial and error.
  2. Gather a stock of basic blocks first so building is not interrupted.
  3. Check your respawn points with M so you know where you will return.
  4. Decide early whether you want PvP or building, and choose an area to match.
  5. Be careful with chat: other players are strangers, and the game has its own privacy policy.

Who it suits

It suits players who enjoy sandbox building and are comfortable in an online space with other people. The chat and PvP make it better suited to older children and adults.
