Birthday sudoku FAQ.
What are the three styles?
Confetti Party (white with a rainbow confetti scatter and a bright HAPPY BIRTHDAY), Vintage (kraft paper with bunting and a letterpress HAPPY birthday), and Cake & Balloons (pink with a layer cake, balloons and gifts — the kid 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 birthday styling is only a frame.
Good for a birthday party?
Very. Print a stack of Cake & Balloons at Beginner or Easy for a kids' party table activity, or Confetti Party at Medium for an adult game night. Include the answer key and it is a calm, no-prep activity.
Can I make it a card or place setting?
Yes — one per page makes a handsome birthday place-setting puzzle or a card insert; print the answer key on the back.
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.
