NEW: Scan a Puzzle Point your camera at a sudoku from a book or newspaper — or import a screenshot — and play it right in the app. Review the scanned grid, fix anything that was misread, and go. NEW: Multiple Games in Progress No more losing a puzzle when you start another. Keep up to 10 games going at once and switch between them from the home screen. IMPROVED: Smarter Difficulty Puzzles are now graded by the solving techniques they actually require, so Easy is truly relaxing and Hard genuinely makes you think. IMPROVED: Cleaner Design A refreshed, unified look across the whole app — and your chosen theme now styles every screen. • Numbers grey out on the pad once all nine are placed • Daily Challenges now resume where you left off • Your progress is saved automatically when you leave the app • Fixed layout issues by keeping the app in portrait
