Sudoku Vault

Sudoku Vault — About This Game

Three board sizes are on offer, from four by four up to the full nine by nine, each with four difficulty levels. Cells are chosen with the mouse or a touchpad and filled from an on-screen number pad, with a notes button for pencil marks. A check button strips out wrong entries and locks correct ones, which makes it friendlier to beginners than most sudoku.

How to Play

Select a cell with the mouse or touchpad and pick a number from the on-screen pad; the Note button toggles pencil marks and Check removes wrong entries.
