## What is SudokuFlow?

Over 500 levels of classic and killer Sudoku — free to start, ad-free, thought-provoking and calming. A clean board with nothing between you and the logic.

Just you, the grid, and the quiet pleasure of thinking clearly.

TWO WAYS TO PLAY
- Classic Sudoku: 265 puzzles in six packs, Starter to Master. Place 1–9 in every row, column and box.
- Killer Sudoku: 300 puzzles in six tiers, Starter to Master. The grid is split into tinted cages, each with a total. The digits in a cage add up to that total and never repeat, and the harder tiers start you with only a handful of numbers.

Switch modes from the menu at any time. Each keeps its own progress.

A NEW PUZZLE EVERY DAY
A free daily sudoku in classic or killer, your pick. Either one keeps your streak going. It's a quiet counter, never a guilt trip.

BEAUTIFUL ON iPAD
A layout built for the big screen: the board and controls sit in one comfortable centered column, in portrait or landscape, and the grid scales beautifully to iPad. The same calm game, with more room to think.

WHY SUDOKUFLOW
- Comfortable input with pencil-mark notes.
- Hints that teach the method — "this row forces a 7" — rather than giving away the answer. In killer, they respect the cage totals too.
- Technique-based grading, so every classic puzzle is rated by the thinking it asks of you.
- Free to try: both modes open with a Starter pack, plus the free daily puzzle.
- Plays offline, wherever your day takes you.

WHAT WE BELIEVE
- No ads, ever.
- Privacy-first. No data monetization.
- Exercising your mind through puzzles is fun.
- From a studio of puzzle aficionados who believe games should be worth your time.
