Easy Sudoku X is the best starting point if you already know basic Sudoku and want to learn the diagonal rule. The grid is still 9x9, but both main diagonals must also contain the numbers 1 to 9 without repeating.
This level keeps the solving path simple. You can focus on understanding how rows, columns, boxes, and diagonals work together without facing advanced patterns too early.
The goal of this level is to help beginners understand Sudoku X one step at a time. Easy puzzles usually provide clearer clues, so the diagonal rule becomes helpful instead of confusing.
Easy Sudoku X follows normal Sudoku rules with one extra diagonal condition.
Imagine a cell on the top-left to bottom-right diagonal. If that diagonal already contains 6, then no other cell on the same diagonal can be 6. Even if 6 looks possible by row and column rules, the diagonal rule removes it.
This is the main idea behind Easy Sudoku X: solve normally, but always check the diagonal before confirming a number in a diagonal cell.
Easy Classic Sudoku is solved with rows, columns, and boxes. Easy Sudoku X adds the two diagonals, so some cells have one extra rule to satisfy.
You are ready for Medium Sudoku X when you can solve easy puzzles while checking both diagonals naturally. Medium puzzles usually require more notes and stronger candidate tracking.
After that, Hard Sudoku X introduces more diagonal pressure, while Expert Sudoku X and Master Sudoku X require deeper solving strategies.
Yes. It is a good beginner level for players who know normal Sudoku rules and want to learn how diagonal Sudoku works.
Usually yes, because diagonal cells have one extra restriction. However, the diagonal rule can also give helpful clues.
Start with normal Sudoku scanning, then check the diagonals for missing numbers and repeated candidates.
The center cell belongs to both diagonals, so it is affected by more rules than most cells in the grid.
Easy Sudoku X is a calm way to learn diagonal Sudoku. Use the normal rules, check both diagonals, and build confidence before moving to more difficult puzzles.
