When I am trying to generate full populated grid I am running into difficulties. My algorithm is Set candidates for each cells. Initialy they are numbers 1 through 9. Pick random cell without value. Select random candidate from that cell and assign it. They are simply a 1 in each of the columns that specify a) which position of the board the number is in, b) what column and number are used, c) what row and number are used, and d) what group and number are used. Note that for b, c, and d, we will have the same "number" per column. That is, if it is covering C x 3, it will also be covering R x. JavaScript Sudoku solver. My wife has developed a passion for Sudoku. I do not share it, I've always thought that this is a problem for computers, not humans, so I've never tried to solve one by hand.

This allows a 4x4 puzzle to be solved using 2 qubits per missing number. The code can also solve 9x9 Sudoku puzzles using 4 qubits per number. However, trying to use more than 8 qubits (2 empty squares) in a simulation becomes very slow, so here we only run it for 1 or 2 missing squares in a 9x9 puzzle. Before I begin explaining how to generate unique Sudoku puzzles, it is important to review the rules of Sudoku. Sudoku is played on a 9x9 grid, sectioned off by rows, columns, and 3x3 boxes.
