How to Play Sudoka Puzzle
Sudoku is a logic puzzle with clear rules that are simple to learn. Here is everything you need to know:
The Rules: A 9×9 grid is divided into nine 3×3 boxes. Some numbers (1-9) are already placed in the grid. Your task is to fill every empty cell so that each row, each column, and each 3×3 box contains every number from 1 to 9 exactly once.
The Core Mechanic: Tap an empty cell to select it, then tap a number from the number pad to place it. Tap again to change your answer. Use the notes function (pencil icon) to enter candidate numbers into a cell when you have not yet determined the final answer.
Objective: Fill the complete 9×9 grid correctly according to the rules. There is always exactly one valid solution for each puzzle.
Game Over: Sudoka Puzzle does not have a traditional game over — you can take as long as you need to complete each puzzle. The timer tracks your completion time for personal improvement tracking.
Gameplay Guide
Essential Solving Techniques
Singles (Naked Single): When a cell has only one possible number based on what is already in its row, column, and box — place that number. This is the most basic technique and applies to all difficulty levels.
Hidden Singles: A number that can only go in one cell within a particular row, column, or box. Scan each unit systematically to identify numbers with only one possible position.
Naked Pairs: Two cells in the same unit that together contain only two candidate numbers. These two numbers can be eliminated as candidates from all other cells in that unit.
Pointing Pairs: When a candidate number in a box can only appear in cells that share the same row or column, that number can be eliminated from the rest of that row or column outside the box.
Box/Line Reduction: When a candidate appears in only one row or column within a box, it can be eliminated from the rest of that row or column.
Using the Notes System
The notes system is the most powerful tool in Sudoka Puzzle. At the start of a challenging puzzle, fill in all candidate numbers using the auto-notes feature. Then, as you place confirmed numbers, the notes automatically update to remove eliminated candidates. This gives you a complete visual overview of all possibilities at all times.
Difficulty Approach
- Easy/Medium: Singles and hidden singles are sufficient to solve the puzzle completely
- Hard: Requires naked and hidden pairs, pointing pairs, and box/line reduction
- Expert/Master: Requires advanced techniques including X-Wings, Swordfish, and chains
Tips & Tricks
Use these pro tips to solve puzzles faster and more confidently:
- Always start with singles. Scan the entire grid for naked singles before applying any advanced technique. They are the most efficient moves available and often trigger chains of further singles.
- Use auto-notes from the start. The auto-notes feature eliminates the most error-prone part of manual Sudoku notation. Enable it at the beginning of every puzzle.
- Scan rows, columns, and boxes separately. When looking for hidden singles, scan each type of unit (row, column, box) independently. Missing hidden singles is the most common stalling point.
- Do not guess. Sudoku is a pure logic puzzle — guessing is never necessary. If you find yourself guessing, you need to apply a more advanced technique or look more carefully at the available candidates.
- Use the hint system to learn techniques. When stuck, use a hint and pay attention to the explanation. Learning why a technique works is more valuable than the solution itself.
- Practice one technique at a time. When moving to a new difficulty level, focus on identifying and applying one new technique until it feels automatic before moving to the next.
- Play the daily challenge every day. The daily challenge puzzle is an excellent learning tool because it is the same puzzle for all players — you can discuss and compare solving approaches with the community.
