Bird Sort FAQ
What is Bird Sort: Song of Yggdrasil?
Bird Sort: Song of Yggdrasil is a free online sorting puzzle. Colorful songbirds are scattered across the branches of the World Tree, and you move them branch by branch until every flock of four matching birds is reunited and flies away.
How do I move birds between branches?
Tap a branch to pick up its topmost bird, then tap another branch to drop it. A bird can land on an empty branch or on top of another bird of the same color. When four birds of one color share a branch, the flock is complete and they fly away together.
How do I free frozen birds?
From Act II onward, Loki seals some birds in ice. Frozen birds cannot be picked up, but every flock you complete sends a pulse of warmth through the tree that thaws one layer of ice from every frozen bird.
Is Bird Sort free and can I play it on my phone?
Yes. Bird Sort: Song of Yggdrasil is completely free, needs no download or sign-up, and runs in any modern browser on desktop, tablet and mobile with full touch support.
How many levels does Bird Sort have?
The story mode has 30 handcrafted levels across four realms of Norse mythology — Midgard, Alfheim, Jotunheim and Asgard — plus an endless mode with procedurally generated waves that keep getting harder.
