Smart Sudoku Widget: Resume Puzzles & Track Progress

Smart Sudoku Widget: Resume Puzzles & Track Progress

Overview
Smart Sudoku Widget is a compact home-screen widget that lets users play, pause, and resume Sudoku puzzles without opening the full app. It focuses on quick interactions, progress continuity, and lightweight tracking.

Key features

• Resume where you left off: Widget saves the current puzzle state so tapping the widget reopens the exact board and cell.
• Progress indicators: Shows percentage complete or number of filled cells at a glance.
• Multiple puzzle slots: Store several in-progress puzzles (e.g., Today, Quick, Challenge) and switch between them from the widget.
• One-tap hints: Reveal a single correct digit or highlight conflicts without leaving the widget.
• Difficulty badges: Small icon or color indicating Easy/Medium/Hard for each saved puzzle.
• Auto-save & versioning: Automatic periodic saves and lightweight history to undo recent moves.
• Sync & backup (optional): Encrypted cloud sync across devices for saved puzzles and progress.
• Accessibility: Large-number mode, high-contrast theme, and VoiceOver/TalkBack support.
• Theming: Light, dark, and accent-color options; adaptive to system appearance.
• Streaks & stats: Tracks daily play streaks, average solve time, and completion rate.

Widget interactions

• Tap: Open full app to continue the puzzle.
• Long-press (or context menu): Quick actions — New puzzle, Resume, Hint, Mark complete.
• Swipe (if supported): Cycle between saved puzzles or difficulty presets.
• Double-tap: Toggle between showing progress percent and time spent.

Data & privacy notes

• Local-first: Puzzle states are stored locally by default; cloud backup is optional and encrypted.
• Minimal telemetry: Only anonymous usage metrics (e.g., active days) are collected if enabled.

Implementation considerations (brief)

• Persist puzzle state as a compact representation (9×9 array + pencil marks).
• Efficient snapshot updates to avoid battery/network overhead.
• Handle widget size classes (small/medium/large) with responsive layouts.
• Provide graceful degradation if sync is unavailable.

Who it’s for

Players who want quick puzzle access, to resume games across short interruptions, and to track casual progress without launching a full app.
