Sudoku Shogun

Start with the Sudoku you know, then take on bigger grids. Free in your browser, no ads, no account.

Five ways to play

Classic Sudoku

Easy, Medium or Hard on a familiar 9×9 grid, with pencil notes, check, undo and redo.

Expand

Solve a grid, then choose a corner for the next one. Each new grid shares a corner cell with an existing grid, so your puzzle grows. Some corners get blocked, so your route matters.

Samusamu

A 57×57 layout of 21 grids. Complete the 20 outer grids to unlock the Middle, the final puzzle. Zoom out for the whole layout, zoom in to focus on one grid.

Daily and weekly

Three daily puzzles and a weekly Samusamu, the same for everyone, with an archive.

Speed

Find the missing digit in a row, column or box. A round starts at 60 seconds.
