Birdzzle: Bird Sort Puzzle

Birdzzle is a brain-training puzzle game with birds. Sort birds on the perches (a bird sort puzzle), solve Queens-style logic puzzles, and raise your own flock in a cozy aviary. Every puzzle is checked to be solvable, and each logic puzzle has exactly one answer.

[Aviary] Relaxing time with your birds
• Clear puzzles to earn coins. Use coins to welcome birds and feed them, and they grow from egg to chick to adult.
• Decorate your aviary your way: seasonal backdrops (spring, summer, autumn, winter), perches and small items. Pin favorite birds to the spot you like, and place as many copies of an item as you own.
• Pet your birds, groom them, copy their songs or search for acorns. The more you play, the closer you get. Find each species' favorite game.
• Choose your home music: standard tune, forest, rain or stream. Birds fall asleep at night. On days you want it easy, use Relaxed Mode (no timer, no mistakes).
• A guide for collecting all 48 species. Only some species are sold in the shop; the rest are found by breeding certain pairs. There are no gachas or random-draw purchases.
• Decor items and growth items are all sold at fixed prices — pick exactly what you like.
• Enter the hourly Bird Contest. Judges and entrants gather in the hall. Raise voice, plumage and wit and aim for first place (scores have no cap; rewards are in-game coins only).
• Grown birds sometimes bring back puzzle hints. Adult birds may lose their spirit now and then and can be revived with medicine (no bird ever leaves).
• Eggs and growth keep progressing while the app is closed (up to 72 hours' worth). But a bird's affection drops if you don't look after it.
• Breeding, hint and spirit-loss probabilities, plus the change history, are always available in the Guide.

[Perch Puzzle] Sort birds and feel the calm
• Gather birds of the same kind on each perch (up to 4 per perch).
• You move the top group of matching birds. Just tap twice to move.
• There is no mistake limit, and undoing and restarting are unlimited and free.
• Four levels, from Easy to Expert. Every puzzle is verified to be solvable.

[Territory Puzzle] A real logic puzzle
• An N×N board is divided into colored "territories".
• Exactly one bird in every row, every column and every territory.
• No two birds may touch, not even diagonally.
• Every puzzle is verified by a dedicated solver and has exactly one answer. In Expert, you can take on advanced reasoning: assume a bird goes in a cell and look for a contradiction.

[Our promises]
• No full-screen ads pop up between games. The only ads are the banner at the bottom of the screen and the video ads you choose to watch for hints or bonus coins.
• Unlimited, free undo/redo. Autosave lets you pause and resume anytime.
• Puzzles and bird raising work without a connection (the contest, friends and backup need one).

[More]
• The Territory Puzzle allows up to 3 mistakes. Clear without hints for bonus coins.
• After clearing, watch an ad to get 5x coins (optional).
• Available in 13 languages.
