See all thinky →About Sudoku Vault
Sudoku Vault is a logic-based puzzle game featuring 4x4, 6x6, and 9x9 boards — each with four difficulty levels: Basic, Normal, Hard, and Expert. Whether you're a beginner or an expert, every grid offers a fresh challenge for your mind. Use smart NOTES to keep track of possibilities, and when you want to check your progress, tap the CHECK button — it will remove incorrect inputs and lock the correct ones, helping you stay focused on the solution.
Expect thinky at its core, with a streak of puzzle woven through the design. Whether you want a quick five-minute break or a longer session, it runs smoothly on just about any device.
A couple of things help once you get going: When you are stuck, undo the last move and look at the board again instead of forcing a fix. Work from the corners and edges inward — they usually have the fewest possible solutions.
Whenever you want it, Sudoku Vault is here on Glaze Games — free, instant, and built to run smoothly without a download.
