All three bands use the full classic 9x9 format. The givens shape the progression, while the saved solving trace verifies the actual technique limit.
Naked singles only. Start here if this is your first classic 9x9 Sudoku.
Naked and hidden singles. A little more open space while staying inside basic singles logic.
Hidden singles required. The fullest easy-level practice before moving to a mixed pack.
Pages 1-24 are one-puzzle activity sheets with name and date lines. Pages 25-36 contain two matching answers per page. No signup and no watermark.
These are Easy Sudoku 1, 9, and 17 from the final downloads—not sample mockups.
31 naked singles · 0 hidden singles
35 naked singles · 0 hidden singles
35 naked singles · 4 hidden singles
In Puzzle 1, row 1, column 7 is 2. Its row, column, and box exclude every other digit.
In Puzzle 17, digit 9 has only one legal place in row 1: row 1, column 3.
If you become stuck, rescan one row, column, or box at a time. Every puzzle finishes without guessing or advanced patterns.
The counts below come from the saved deterministic trace for each final grid.

A complete search counts solutions up to two. Publication requires exactly one answer for every puzzle.
All nine rows, nine columns, and nine boxes in each completed grid must contain digits 1-9 exactly once.
Puzzle strings, clue masks, and full solutions are compared with the mixed-level parent collection; exact reuse stops the build.
