Birdzzle: Bird Logic Puzzle

Birdzzle is a guess-free logic puzzle where you collect and raise birds as you play. Enjoy two kinds of puzzles — the Territory Puzzle (Star Battle / Queens style) and the Perch Puzzle (bird sorting) — with only puzzles that are guaranteed solvable. [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] Pure logic, zero guessing • 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. You solve by reasoning, not by luck. [Aviary] Collect and raise birds • Clear puzzles to earn coins. Use coins to welcome birds and feed them, and they grow from egg to chick to adult. • 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. • 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. • Enter the hourly Bird Contest and compete for a rank (rewards are in-game coins and items only). • Breeding, hint and spirit-loss probabilities, plus the change history, are always available on the Probabilities screen. [Our promises] • We never serve puzzles that require guessing. • No full-screen ads while you solve (only after you clear a puzzle). • 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.
