The Sudoku Labyrinth is a special kind of Sudoku, the goal is to place a sequence of numbers (1-2-3) as often in a path in a grid such that at the end, like a regular Sudoku, no numbers repeat in each column and row. But the similarity end there. You must enter the sequence of numbers (1-2-3) following a path . Each grid has a path, visiting all cells either in a spiral or labyrinth form. This type of puzzle, also known as magic spiral, is addictive and demands a lot of reasoning skill. You will find these puzzles fun; they are ideal for relaxation.
