Build a world worth squawking about

Turn a blank grid into your own bird arena. Bird Burst's World Builder works with touch or a mouse, and your local draft waits for you between visits.

Paint, stack and experiment

Choose stone, spring, moss, wind or portal blocks. Build stacks, rotate the camera, zoom in, erase, undo and redo. Paired portals send the parrot somewhere unexpected; springs and wind change the flight.

Try a test flight

Test your draft using the same physics and renderer as a real game. Test flights award no XP and do not count toward player statistics, so you can experiment freely.

Share with every player

Sign in to publish a world. A published copy becomes available in the community world picker, including for group games. Your later draft edits do not change that published version. Players can remix a community world into a new draft.

Difficulty is measured automatically

The server runs deterministic reference-bird trials with the shared game physics to grade each published layout. The result helps compare worlds; it is not a promise of how easy or hard every human player will find them. Sealed arenas and invalid portal pairs cannot be published.

Unlock the campaign

Jungle Nest is available at level 1. Each XP level unlocks another campaign world. The picker shows available worlds, locked worlds and how much XP remains until the next unlock.
