Airdoku - Daily Logic Puzzle

Airdoku is a calm, free logic puzzle game you can play offline. Place one plane in every colored zone, one per row and column, with no two planes touching. A new daily puzzle every day, boards from 5×5 to 10×10, and every single board is solvable by pure logic. No guessing, ever.

If you enjoy sudoku, nonograms or star battle puzzles, you will feel right at home: the rules fit on a napkin, but the deductions get deliciously tricky.

■ How to play
• Place exactly one plane in each colored zone
• Each row and each column holds only one plane
• Planes can't touch each other, not even diagonally
• Tap a cell once to mark it with a cloud ("no plane here")
• Double tap a cell to place a plane
• Drag across cells to mark several clouds at once
• A wrong placement costs a heart. You have 3 hearts per board

■ A new Daily Puzzle every day
Every day brings a fresh daily logic puzzle. Solve it to keep your daily streak alive. The daily board is generated on your phone, so it works even without an internet connection.

■ Every logic puzzle has exactly one solution
Each board is checked by a logic solver before you see it: one unique solution, always reachable step by step. No trial and error, no dead ends, just clean deduction.

■ Endless campaign and Quick Play
• Endless campaign: levels keep coming and grow from a gentle 5×5 all the way up to a demanding 10×10
• Quick Play: jump straight into an Easy 6×6, Medium 8×8 or Hard 10×10 board whenever you have a few minutes
• Difficulty is rated by the solving techniques a board needs, so Easy really is easy and Hard is a real logic puzzle challenge

■ Tools that make solving comfortable
• Note mode: pencil in possible planes and clouds while you think it through
• Auto clouds: placing a plane automatically marks every cell it blocks (you can turn this off)
• Undo: step back through placements, clouds and notes
• Hint: one free hint on every board shows the next plane that logic can prove; more hints by watching a short ad
• Out of hearts? Watch an ad to get one back, once per board
• Timer you can show or hide

■ Play offline, anywhere
Airdoku works without Wi-Fi: on a plane, on the subway, in a waiting room. Your progress is saved automatically, so you can always pick up right where you left off.
