Some cells already contain numbers, known as \"givens\". The goal is to fill in the empty cells, one number in each, so that each column, row, and region contains the numbers 1 through 16 exactly once. Each number in the solution therefore occurs only once in each of three \"directions\", hence the \"single numbers\" implied by the puzzle's name.\u003c\/p\u003e\n\n\u003ch2\u003eDifficulty Level\u003c\/h2\u003e\n\n\u003cp\u003eThese puzzles range from hard to master difficulty, providing substantial challenge for solvers who have moved beyond standard 9x9 Sudoku grids.
