Full description

Welcome to a fresh and engaging Sudoku experience! This app blends the classic logic puzzle with a clean design and tools that help you improve. Whether you’re new or a pro, you’ll find the perfect challenge. Features Five difficulty levels — from Easy to Insane. Smart hint system — a gentle nudge without spoiling everything. Learning engine — learn techniques (Hidden/Naked Singles, X-Wing, etc.) with explanations. Pencil notes — track small candidates in each cell, just like on paper. Magic Pencil — auto-fill reasonable candidates with one tap. Handwriting (Digital Ink) — write the digit; the app recognizes and fills it in. Color themes — choose Green, Blue, or Lavender in light/dark mode. Undo & Erase — experiment freely. Auto-save — continue where you left off. Offline — play without an internet connection. Ad control No forced ads. All ads are optional (rewarded). Some bonuses (e.g., extra hint) can also be unlocked via an optional rewarded ad — your choice. How to play Fill the 9×9 grid so that every row, column, and 3×3 box contains the digits 1–9. Use logic — and the built-in tools — to master each board.
