How to play — Sudoku Vault

Press play and Sudoku Vault loads inside the page — there is no launcher and nothing to sign up for. Look at the whole board before your first move; the later levels leave less room for mistakes. On a phone or tablet the same game runs with touch controls, so the layout adapts to the smaller screen. The exact keys are shown in the game itself, and any in-game menu is available once it loads.
