Print the puzzle sheets
The three boards below are generated from fixed seeds using LinkParty’s Sudoku generator. Each board is checked for exactly one solution before publication. They are not assigned a difficulty rating because clue count alone does not measure solving difficulty. Use the Print puzzle sheets button or your browser’s print command. Print styling keeps the answer grids off the sheets.
Follow the three constraints
Fill each empty cell with a digit from 1 to 9. Every row, column and three-by-three box must contain each digit once. Given digits are fixed clues, not editable guesses. Start with a row, column or box that has several known digits, and list what is missing before writing a number. A locally legal guess is not necessarily part of the final solution.
Use candidates deliberately
For one empty cell, eliminate digits already present in its row, column and box. If only one remains, the cell is forced. Also look for a digit that has only one possible position within a unit. Recheck neighbouring candidates after placing a digit. If a contradiction appears, trace your last uncertain entries rather than erasing the original clues or changing the puzzle.
Check answers without spoiling the whole board
Each solution is inside a separate expandable section. Open only the one you need and compare a small area first. The interactive Sudoku on the main games page offers a different way to practise in the browser; these printable sheets remain stable so you can discuss a particular board with another person. Keep notes on which rule resolved a cell instead of using the answer grid as an unexplained replacement.
