## Version history (last 4 releases)

### 1.0.3 — 2026-08-04

Sharper puzzle scanning — printed Classic grids now import reliably from the camera, with gentle on-screen tips if the scan needs a moment. And the optional daily reminder now badges the app icon so you never miss the day's puzzles.

### 1.0.2 — 2026-07-16

Learn on a puzzle you scanned. Point the camera at any printed Sudoku, then walk that exact board through the solving techniques, step by step.

How to Play. A visual walkthrough of the rules — one for Classic, one for Samurai — the first time you open each.

Per-level stats and 10 new achievements. Classic and Samurai are separate ladders now, and Samurai counts for more.

Scanning is faster and steadier. The camera opens straight away, and the digits it reads sit exactly on the grid instead of trailing behind it.

Scanning now works with VoiceOver. The app speaks what the camera can see — whether it has found a grid, whether to hold steady — so a scan can be done without looking at the screen.

Fixed: the Undo / Redo / Erase / Hint bar now appears in your language.

### 1.0.1 — 2026-07-14

• Share a puzzle — friends can play it instantly, no download needed.
• Refined translations across every language.
• Small fixes and polish.

Enjoying Samuraiku? A quick rating means a lot to a solo developer — thank you!
