Airplane Sudoku

Game Description
Sudoku that works at 30,000 feet, and teaches you how to solve it.
5,000 puzzles are built into the app. No account, no sign-up, no connection needed — on a plane, on the underground, or anywhere with no signal, it plays exactly the same.
LEARN THE TECHNIQUES, NOT JUST THE ANSWER
Most sudoku apps have a hint button that fills in a square. This one explains the reasoning first.
Ask for a hint and it names the technique and tells you where to look. Ask again and it shows you the argument, highlighting the squares it applies to. Only then, if you still want it, does it place the number.
There is also a technique school: seven short lessons covering locked candidates, naked and hidden pairs, naked triples, X-Wing, XY-Wing and swordfish. Every lesson uses a real position from the puzzles in the app, chosen so the technique is genuinely the next step.
DIFFICULTY THAT MEANS SOMETHING
Most apps decide difficulty by counting how many numbers you start with, which tells you very little. Here every puzzle was solved by computer using the same techniques a person would, and graded by how much work it actually demands.
Ten levels, from Taxi to Mach 1, each with 500 puzzles. Levels nine and ten genuinely cannot be finished by pattern-spotting alone.
A REASON TO COME BACK
- A daily challenge that gets harder through the week, from an easy Monday to a demanding Sunday
- A streak, shown as the current week so you can see at a glance what you have done
- Ten pilot ranks, from Ground Crew to Ace, each unlocking new scenery for the whole app
BUILT TO BE PLEASANT
- Pencil marks, with automatic cleanup when you place a number
- Undo that forgives the mistake it undoes
- A practice mode with no mistake limit, for when three strikes feels harsh
- Your game is saved the moment you leave, mid-puzzle and mid-thought
- Dark mode, or follow your system setting
- English and German throughout, including the lessons and hints
- Large, clear type and full screen-reader labels on the grid
