Easy Sudoku online
Easy is Sudoku Rivals' perfect entry point: boards designed to teach you the game without frustration, solvable with the two most basic logical techniques.
What 'Easy' means in Sudoku Rivals
An Easy Sudoku in Sudoku Rivals can always be solved, cell by cell, using only the two simplest logical techniques — no need to pencil in candidates everywhere or combine several rules at once to keep moving.
Who it's for
Anyone learning how to play Sudoku, anyone who wants a relaxed game without overthinking it, or anyone who prefers to focus on speed over logical difficulty — for example in Fast or Ultra mode.
Basic techniques: Naked Single and Hidden Single
Naked Single — when an empty cell has only one possible number left (every other digit already appears in its row, column, or 3×3 box), that number goes there.
Hidden Single — when a number can only go in one specific cell within a row, column, or box, even if that cell still has other candidates pencilled in.
With these two techniques you can solve any Easy Sudoku from start to finish. You can review them in more detail in Sudoku Techniques.
When you want more of a challenge
Once you've mastered Easy, the natural next step is Medium Sudoku, which introduces Locked Candidates and pairs. If you'd rather review the basic rules first, the full guide is at How to Play Sudoku.
