Easy Sudoku X
Easy Sudoku X — around 36 given digits. The diagonals give you two extra units of constraint right out of the gate; most solvers finish in 5–9 minutes.
Easy puzzles are solvable with plain row, column, and box scanning — no pencil-mark techniques required. A good choice for kids learning the rules, for warm-ups, or for a relaxed evening solve.
Free downloadable Sudoku puzzles across four variants — Classic, Killer, Sudoku X, and Hyper — with answer keys on the back pages. No accounts, no colour ink.
