About Hoot & Fox

Hoot & Fox is a cosy logic puzzle about owls and foxes, played on a simple grid with no luck and no chance — just deduction.

Fill every cell with an owl or a fox so each row and column balances, and no three of the same animal sit together. Every puzzle has exactly one solution, and every step can be reasoned out — no guessing required.

Features

  • Journey: hundreds of hand-graded levels across cosy woodland Glades, rising gently from your first tap to twelve-by-twelve grids with linking clues
  • Daily puzzle: one puzzle for everyone, every day, with a streak to keep and freezes to protect it
  • Weekly Grand: one big 14×14 puzzle each week, the same for everyone
  • Weekly Grove League: race the clock against players worldwide, built from your Daily times
  • Endless mode: pick a size, pick a challenge, play as long as you like
  • Hints that teach: Pip the owl walks you through a real technique step by step, so you learn the trick rather than just being handed the answer
  • The Burrow: pairs, boards, companions and solve celebrations, bought with acorns you earn by playing. Nothing you buy changes the difficulty
  • Field Guide: a growing library of the logic techniques you discover as you play

Designed to be unplugged

Hoot & Fox works everywhere, always: on a plane, underground, at a bus stop. Only the Daily leaderboard and league need a connection — everything else works with no wifi at all, forever.

No pressure

There's no timer forced on you, no shouting, no frantic animations. Turn on Zen mode to remove hearts altogether and just enjoy the puzzle. Colourblind-friendly palettes, large cells with pinch-to-zoom, and keyboard controls on iPad are built in.

Hoot & Fox is free to play, supported by optional ads you can remove entirely with a single one-time purchase. Optional acorn packs are available if you'd like more acorns sooner — no subscriptions, ever.

Meet Pip the owl and Rue the fox, and settle into a quiet afternoon in the Grove.
