A Sudoku app for iPhone with 2,000 puzzles, guided technique lessons and a daily puzzle that works offline. No ads or accounts.
I love doing a daily Sudoku, but I often found the apps I used frustrating. I wanted something that felt simple and elegant, with controls that got out of the way of the puzzle. So I built Blossom.
The part I’m happiest with is that I keep coming back to play it. It’s still a slightly strange feeling to sit down and play a game I wrote, but it’s become part of my routine.
Learn as you play
Puzzles are graded by the techniques they require. Guided lessons explain a pattern using a real puzzle position, then give you puzzles that use it. Statistics track your progress across the techniques.
