Halloween sudoku FAQ.
Is it scary?
No. The imagery stays friendly — bats and pumpkins, nothing gory. Candy Corn is built for classrooms and younger kids; Modern Gothic is the grown-up option for a costume party.
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 Halloween styling is only a frame.
Good for a classroom party?
Very. Print a stack of Candy Corn at Easy or Medium, include the answer key, and you have a calm, no-prep activity for the party.
Does it print well at home?
Yes — solid, printer-friendly colors on a home inkjet 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.
