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.
