Start a new puzzle from the difficulty menu, then tap a cell and choose a number to place it. A few tips:

Correct numbers lock in with a sound; a wrong number briefly clears itself.
The number list shows how many of each digit are still left to place.
Change the grid's look any time from the theme picker — there are 23 to choose from.

App is behaving oddly: Force close the app and reopen. If needed, restart your device.
How do I enter a number? Tap a cell to select it, then tap a number to place it. Tap a filled cell you entered to clear or change it.
Are the puzzles always solvable? Yes — every board is generated with exactly one valid solution, so you never need to guess.
How do the difficulty levels work? Higher difficulties leave more cells blank: Trivial is the gentlest and Extreme the toughest.
How do ranks and best times work? Each solved puzzle earns points that raise your rank, and your fastest time is kept for each difficulty.
Does milliSudoku need an internet connection? No — puzzles are generated on your device, so the game works fully offline.
Does milliSudoku collect data? No — see the Privacy Policy.
