Getting started in your build area

Step
In short When you join, you get your own build area ready to go.

When you join, you get your own build area ready to go. Before you start on anything big, take a moment to look around and test the basic controls.

  1. Look around walk around your area to get a feel for how much space you have to work with.
  2. Try placing a block place one block somewhere, then remove it, so you know both controls before you need them.
  3. Change the color pick a color for a block to see how the color picker works.

Building with blocks

Tips

Blocks come in a range of colors and can be placed, moved, or deleted at any time, so there is no penalty for experimenting.

Tips worth knowing
  • Color changes the look of a build dramatically even when the shape stays exactly the same.
  • Add lighting to your build to make it look more three-dimensional.
  • Because you can delete and replace blocks freely, treat early attempts as drafts rather than mistakes.
03

Vehicles — hoverboard, car, and rocket

Summary

Three vehicles are available: hoverboard, car, and rocket. They bring your builds to life.

  • Hoverboard suited to smooth gliding courses with a floating feel.
  • Car the natural fit for race tracks and roads.
  • Rocket adds vertical action when your build goes upward.
04

Doors and realistic entrances

Check

Doors were added to the game so that houses, shops, halls, and any other enclosed building can have a real entrance. They can be customized in color and size.

  • Use a door wherever a build needs a way in and out.
  • In multiplayer, doors work well as dividers between areas that different players are responsible for.
05

Saving and returning to your build

Warn

Everything you place is stored on a private server tied to your game. Logging out does not erase your progress.

Worth watching out for
You can leave and come back later and your build will be exactly as you left it.
All blocks, vehicles, and doors are available without any payment, so nothing is locked behind a purchase.
There are no rules or objectives.

No. Every build is saved automatically to a private server. The next time you log in, everything will be exactly where you left it.

How does the daily top build feature work?

Take a screenshot of your finished build and submit it on the game's communications server. Each day one build is chosen and displayed at the spawn point where every player can see it.
