Grandma & Grandpa's Sudoku

Classic Sudoku. Pour a cup of tea and take your time.

Fill every row, every column and every 3×3 box with the numbers 1 to 9, once each. There are no sums to do: it is all about where each number fits.

Before you see a puzzle, the game solves it step by step, the way a person would, and gives it the level of the hardest step it needs. Every puzzle has exactly one solution and can be solved by reasoning alone, so guessing is never needed.

What's in it

Three levels, honestly graded. Easy needs only the simplest steps. Medium calls for pairs. Hard needs a triple, an X-Wing or an XY-Wing.
Pencil marks. Note up to nine possible numbers in any empty square. Undo brings them back.
Help without giving the game away. Clashing numbers are underlined, and each number button shows how many more can still go on the board.
A gentle start on Easy. Check Solution and Hint, as often as you wish. No score and no penalty.
How to play. The rules, the controls and a few tips, one click from the first screen.
Your colours. Light, Dark or System theme, in coral, teal, leaf green or ochre.
Mouse or keyboard. Play entirely from the keyboard if you prefer.
Saved as you play. Continue takes you back to the same puzzle, timer included.

What's not in it

Ads. None. Anywhere.
In-app purchases. There is nothing to buy.
Accounts or sign-in. No registration and no cloud sync.
An internet connection. Puzzles are created and checked on your PC.
Tracking. No analytics or advertising identifiers.

Mini Sudoku

Sudoku, without the distractions.

No ads popping up between puzzles. No “watch this video for a hint.” No account to create, no leaderboard to feel bad about, no subscription waiting to ambush you on day 8.

Just Sudoku — the way it was before someone decided every app needed a monetisation strategy.

Mini Sudoku gives you three difficulties (Easy, Medium, Hard), a clean number pad that quietly tracks how many of each digit you've got left to place, and a theme that follows your system — or lets you pick Light or Dark yourself.

What's in it

Your pace, your puzzle. Easy, Medium, or Hard, with every puzzle freshly generated to have exactly one solution.
A number pad that helps. Live remaining-digit counts, so you always know what's left to place.
Make yourself comfortable. Light, Dark, or System theme.
Keys or taps. Full keyboard support if you'd rather not touch the screen.
Life can interrupt. Pause and resume anytime, with your puzzle where you left it.

What's not in it

Ads. None. Anywhere.
In-app purchases. There's nothing to buy.
Accounts or sign-in. No registration, no cloud sync.
An internet requirement. It works the same with Wi-Fi off, because the game never needed it.
Tracking. No analytics or advertising identifiers.

If you just want to solve a Sudoku puzzle without the app trying to sell you something along the way, this is that app.
