Not every puzzle needs 256 cells. This is where we put fresh takes on the classic 9×9 grid — starting with Sudoku Number Search. Same commitment to hand-verified, unique-solution puzzles, in a more familiar format.
Two live variants so far, with more on the way as we build out this side of the site.
King-Size 16×16 is our flagship, but the classic 9×9 grid is where most solvers start. This section keeps that format, with new mechanics layered on.
Every 9×9 variant gets the same unique-solution guarantee as our 16×16 books — no guessing, no ambiguous grids.
