## What is Sudoku Lumo?

Sudoku the way it should be: a clean, calm board, puzzles you can actually finish, and hints that make you a better player instead of just handing you the answer.

Every puzzle is generated with exactly one solution and hand-tuned to its difficulty, so you always get a fair, satisfying solve — never a lucky guess.

WHY YOU'LL LOVE IT
• Three grid sizes — 4x4 and 6x6 for a quick warm-up, classic 9x9 for the real thing.
• Three difficulties — Easy, Medium, and Hard, tuned to the techniques each puzzle actually needs.
• Smart hints that teach — every hint names the real solving technique behind it (Naked Single, Hidden Single, Pointing Pair, X-Wing and more), so you learn as you play.
• Pencil notes — jot candidates into any cell, with automatic clean-up as you place numbers.
• Undo, redo & erase — experiment freely and step back anytime.
• Check your board — spot mistakes on demand before they cost you.
• Never lose progress — your game autosaves and is waiting exactly where you left off.

TRACK YOUR PROGRESS
• Lifetime stats: games solved, best time, average time, and total hints used.
• Daily streaks that reward you for showing up every day.
• A history of your recent games, completed and in-progress.

PLAY ANYWHERE
• Fully playable offline — no account, no login, no sign-up. Just open and play.
• Designed for iPhone and iPad, in portrait or landscape.
• A warm, easy-on-the-eyes board built for long, relaxing sessions.

FREE TO PLAY
Sudoku is free. A few ads keep it that way, and extra hints, checks, or a full solve are always optional — never required to finish a puzzle.

Whether you want a two-minute brain break or a deep, tricky 9x9 to unwind with, Sudoku is ready. Download it now and start your streak today.
