Stuck on a puzzle? The demo includes the same layered hint system as the full version:
In the demo, you can use up to 2 hints per puzzle.
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.
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.
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.
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.

Your save data carries over seamlessly to the full version. If you decide to upgrade later, your progress will be preserved and you can continue right where you left off.
