## What is Sudoku Note?

Writing something by hand
can feel a little inconvenient,
yet strangely satisfying.

Sudoku Note lets you
write, erase, and take notes using Apple Pencil (or your finger),
so you can enjoy Sudoku calmly, just like on paper.

Instead of tapping a number pad,
you simply write numbers, and handwriting recognition does the rest.

Puzzles are not random.
They are carefully designed with step-by-step difficulty
based on solving techniques.

Every puzzle includes a detailed explanation along with the solving techniques.

Experience a different kind of Sudoku.
