Rated Sudoku Demo is a surprisingly rich Sudoku experience, with enough content and features to satisfy the Sudoku needs of 50% of players, including well written lessons, layered hints, rated games and a full Sudoku Editor for unlimited play beyond the built-in content.

Designed for both complete beginners and experienced players, the demo focuses on learning by doing, with carefully selected puzzles that teach the rules and core solving techniques step by step.

Hint System - Smart Help When You Need It

Stuck on a puzzle? The demo includes the same layered hint system as the full version:

First click: gives you a subtle nudge with partial highlighting of the key area, so you still have room to think it through and spot the move yourself
Second click: reveals a full hint with complete highlighting and a clear explanation of the logic, so you understand why the move works

In the demo, you can use up to 2 hints per puzzle.

Play - Efficient Input System

Tired of slow manual candidate entry and accidental mistakes? Our unique skill input system makes Sudoku faster and cleaner to play. Spot a pattern, select the relevant cell, click the matching skill, and the game performs the eliminations for you automatically. If the skill does not apply, nothing happens, so you can stay focused on solving instead of managing candidates by hand.

Campaign - Learn Step by Step

The demo includes the first 5 Beginner Campaign levels and the first 5 Practice Campaign levels, offering around 10 hours of content. You will learn the rules of Sudoku from the ground up, then move into technique-focused lessons covering Hidden Singles, Naked Singles, Pointing/Claiming, Naked Sets and Hidden Sets.

Rated Game - Skill-Matched Challenge

The demo also includes Rated Game mode, which matches you with puzzles around your current level so you can keep testing your skills outside the campaign. In the demo, Rated Game is available up to 1600 rating.

Sudoku Editor - Unlimited Play

The Sudoku Editor is fully available in the demo. Enter any puzzle you want to play, or generate fresh ones whenever you like. This means the demo is not limited to its built-in campaign content. Even after finishing the included levels, you can keep playing as much as you want with your own puzzles or newly generated ones.
