Easy vs Medium Sudoku: What Changes and When You Should Level Up

You have been solving easy Sudoku puzzles and loving it. But lately, they feel a little too easy. You finish them faster. You do not need to think as hard. You are ready for more.

Here is what changes at the medium level — and how to handle it.

What Easy Sudoku Teaches You

Easy puzzles use two basic techniques: naked singles (cells with only one possibility) and basic elimination (if a number exists in a row, it cannot appear again). These techniques solve about 90% of easy grids.

What Medium Sudoku Demands

Medium puzzles require techniques that easy puzzles never ask for.

Hidden pairs: two numbers that can only go in two specific cells within a row, column, or box — even if those cells appear to have other possibilities.

Pointing pairs: when a number in a box can only go in cells that share a row or column, you can eliminate that number from the rest of that row or column.

Box/line reduction: the reverse of pointing pairs — when a row or column limits where a number can go within a box.

These techniques sound complicated on paper but become intuitive with practice.

How to Know You Are Ready

You are ready for medium when easy puzzles take you under 10 minutes, when you rarely need to erase, and when the solving process feels automatic rather than challenging.
