Background A Sudoku board is made up of nine boxes. Boxes (container for nine cells) are listed from top-to-bottom, left-to-right indexed from zero. Cells are listed from top-to-bottom, left-to-right, indexed from zero. All valid payloads and responses must use well-formed JSON. “cells” is returned as follows: “cells”: [[<nine values from top-left>], [<nine values from top-middle>], …]
