## What is DonutDoku?

Place one donut in every coloured area. No two may share a row or a column, and no two may touch - not even at a corner. That is the whole game, and it is enough to keep you thinking for months.

SOLVABLE, NEVER GUESSABLE
Every one of the 2,281 boards has exactly one answer, and every one can be reached by reasoning. We check that with our own solver before a board ships: if it cannot be finished without a guess, it does not go in. You will never be asked to flip a coin.

A LADDER THAT ACTUALLY CLIMBS
Boards start at 4x4 and grow to 10x10. Harder ones are not just bigger - about one in six needs a real deduction, where you assume a square and follow it to a contradiction. Those are marked "Hard" so you know what you are walking into, and they are spread through the ladder rather than saved up for the end.

RACE A FRIEND
Two phones, same board, no server and no account. One life and no hints - a single wrong donut ends it, so it rewards thinking rather than tapping fast. Works over Wi-Fi or Bluetooth, in the same room.

A BOARD A DAY
The Daily box gives every player the same puzzle, worked out from the date. No connection needed.

MADE TO BE QUIET
No ads. No accounts. No tracking. No internet connection of any kind. Nothing you do leaves your phone. It works in aeroplane mode, on the underground, anywhere.

Fully playable in English, Hebrew and Spanish, right-to-left included.
