Sudoku 15x15 is a supersized variation that stretches the classic puzzle onto a grid of 15 rows and 15 columns. The board is divided into square regions of 3x5 cells, and every one of these must follow the same strict placement rules as rows and columns. The challenge is to use the numbers 1 through 15 to fill every space without repeating any digit in a row, column, or region. The larger size brings a unique rhythm to solving: patterns are more spread out, and spotting logical connections often requires scanning across wider distances. It's a puzzle of patience and method rather than speed, where each correct move gradually brings clarity to the whole grid.
At the start, some cells are already filled in, giving you anchors to begin your reasoning. From these initial hints, you eliminate options, track possible placements, and slowly uncover the solution. Guessing is never required-logic alone will always guide you to the end. This easy 15x15 version is perfect for players who want to move beyond smaller boards like 9x9 or 12x12, but still prefer a puzzle that feels fair and solvable. It offers a satisfying balance between accessibility and depth, making it a great way to train focus, practice logical thinking, and develop persistence. Playing Sudoku 15x15 is not just a pastime It's a mental workout that rewards steady progress and leaves you with the satisfaction of completing an impressive, expansive puzzle.
