Sudoku
The classic number puzzle: a nine-by-nine grid where every row, column and box has to hold each digit from one to nine exactly once. Winters Puzzles generates a fresh board every time you play, checks it has exactly one solution before dealing it, and lets you pencil in candidates while you work.
How it works
- Every row, column, and 3×3 box holds 1–9 exactly once.
- Tap a cell, then a number. Tap the number again to clear it.
- Notes mode pencils in candidates you're not sure about.
The same rules are shown inside the app, on the puzzle’s overview screen — one tap opens the difficulty choice and how to play together, so you never have to go looking for them.
Good if you want…
- A puzzle you already know the rules to
- Somewhere between five minutes and half an hour
- Choosing your own difficulty, from gentle to genuinely hard
