#### Sudoku on notebook paper — 100 levels from 4x4 to 25x25

A quiet sudoku on notebook paper. A hundred levels lead from a 4x4 warm-up
all the way to a 25x25 board, and every one of them has exactly one solution.

WHAT YOU GET

* 100 levels, board sizes 4x4, 6x6, 8x8, 9x9, 10x10, 12x12, 15x15, 16x16,
  20x20 and 25x25 — the clues thin out as you go
* A daily puzzle in three sizes and three difficulties, the same one for
  everybody, new every day
* Notes, three hints per level, undo, board rotation and zoom
* One to three stars per level, measured against the fewest possible moves
* Every board you solve is kept as a picture on the achievements wall
* Play with the mouse or entirely from the keyboard
* 22 languages

HOW IT PLAYS

Pick a cell and type a digit, or use the number bar; the radial picker is
there if you prefer it. Conflicting digits are marked, matching digits are
highlighted, and the pencil mode keeps a tentative value in a cell until you
are sure. The clock runs while you think, the board saves itself while you
play, and you can put it down mid-puzzle and pick it up days later.

Keyboard: arrow keys move, 1-9 place a digit, Backspace clears, N is the
pencil, U undoes, H asks for a hint, R restarts, Space pauses, F11 fills the
screen.
