What makes a Sudoku "easy"

Difficulty in Sudoku comes down to two things: how many numbers are given at the start, and which logical techniques you need to find the rest. Easy puzzles give you between 35 and 45 of the 81 cells filled in. That generosity means you almost never have to juggle candidate lists — the next number is usually visible if you just scan the right row, column, or 3×3 box.

Easy Sudoku is the grade where the puzzle itself does most of the teaching. You build pattern recognition for how the three constraints (row, column, box) interact without ever feeling stuck. If you've never finished a Sudoku before, this is where you start.

The only two techniques you need

1. Naked Singles

A cell that has only one possible number based on what's already in its row, column, and box. Look at a blank cell and ask: "What numbers can't go here?" If the answer leaves just one candidate, that's your answer.

2. Hidden Singles

A number that can only fit in one cell of a given row, column, or box — even though that cell might superficially allow other numbers. Pick a digit, say 7, and check where it can still go in a specific 3×3 box. If there's only one legal spot, place it.

That's it. These two techniques solve every easy Sudoku on this site. You will not need pencil marks, guessing, or advanced patterns.

Tips for faster easy solves

• Scan by digit, not by cell. Pick a number like 5 and find every row, column, and box where it's still missing. This is faster than staring at blank cells.
• Start with the most-filled rows, columns, and boxes. If a box already has 6 digits, the remaining 3 cells are usually trivial to place.
• Look for "lines of three." When a digit appears in two of the three stacked boxes, the third box's placement is often forced to a single row.
• Don't guess. Every puzzle on this site has one unique solution reachable by logic alone. If you're stuck, you missed something — take a break, come back, rescan.

Who easy Sudoku is for

Anyone new to Sudoku. Kids from 8 years old (great for logical reasoning and number recognition). Adults returning to the puzzle after years away. People who want a relaxing 10-minute break without the frustration of getting stuck. Teachers using Sudoku in classrooms. Seniors looking for mental exercise that doesn't feel like homework.

When easy feels boring — when you finish under 6 minutes without concentration — move up to medium.
