Back to School sudoku FAQ.
What are the three styles?
Composition (a marbled black-and-white notebook cover with a red margin rule), School Supplies (cream card with a pencil-apple-book-ruler-scissors row), and Chalkboard (a wood-framed slate with a chalk 'Welcome back, class!' — the favorite).
Is the puzzle real?
Yes — it is the full 9x9 engine, single-solution verified, with difficulty graded by the technique each puzzle actually needs. The school styling is only a frame.
Good for the classroom?
Very. Print a stack at Beginner or Easy for the first week, early finishers, or a calm sub-plan activity; include the answer key and it is zero-prep. Medium and up work for older students.
Can teachers use these freely?
Yes — free for classroom use, no signup or watermark. Print a class set of any style and difficulty.
Does it print well at school?
Yes — solid, printer-friendly colors on a copier or laser. For a no-frills practice stack use the plain classic generator instead.
Is it free?
Completely — no signup, no email, no watermark. Print as many as you like.
