What makes these easy
Every cell can be filled by looking at what is already there — scanning a row, a column, or a box until only one number fits. No guessing, no notation, no advanced patterns.
Every puzzle has exactly one solution
This is the part most free sudoku sheets get wrong. Puzzles here are built by removing clues from a completed grid one at a time and re-solving after every removal — if a clue’s absence would allow a second solution, it is put back. The answer key is the grid the puzzle was carved from, so it cannot disagree with the puzzle.
Other difficulties
- Medium sudoku — someone comfortable with the rules who wants a real sitting.
- Hard sudoku — a regular solver.
- Expert sudoku — people who find hard puzzles too quick.
