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. PART OF THE PUZZLE MASTER COLLECTION SudokuFlow belongs to the Puzzle Master Collection, our growing family of calm, ad-free puzzle games from a studio of puzzle aficionados.

Verdict
The clearest difference is ads: SudokuFlow at none against 10 Seconds Left's shown. SudokuFlow also leads on ratings volume (5 vs 1). 10 Seconds Left's advantage is rating (5.0 vs 4.6) and monetization model (free vs freemium). On price, in-app purchases and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. SudokuFlow sells 5 in-app purchases, starting at $1.99 per 7 days and 10 Seconds Left sells 10 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.
10 Seconds Left holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: SudokuFlow has 5 ratings behind it against 1, so its average is the more settled of the two.
SudokuFlow ships an update every 8 days, 10 Seconds Left every 2 days. The most recent releases landed on November 10, 2026 and October 31, 2026 respectively.
