Cheeky raiders are coming down the forest path to take the owls' winter acorn store. Tap a glowing perch to put an owl there. Owls shoo raiders: when a raider loses its nerve it runs home and drops acorns. Spend acorns on more owls and upgrades.

Each raider that reaches the store takes a basket. Keep at least one basket until the last wave to win. Fewer baskets lost = more stars.

Waves start by themselves after a short countdown. Tap GO to start the next one early (and get a few bonus acorns).

Upgrades: tap an owl. Each owl has two paths to choose from, with three steps each. You can also send an owl home to get most of its acorns back.

Leaf-sneaks hide under leaves: a Moon-lantern owl lights them up so the other owls can see them. Magpies fly over feathers, and hedgehogs curl up, so stuns and gusts work half as well on them.

Mouse or touch: tap a perch or an owl. Keys: arrows pick a perch, Enter opens it, 1 to 8 choose an owl, A or B upgrade, X sends it home, Space starts the next wave, F speed, P pause, M sound.

Long Night: waves never stop: how far can you go? Daily challenge: a new map, twist and raider mix each day, the same for everyone.
