FAQ
Large Sudoku FAQ
Frequently asked questions about senior-friendly play, printable puzzles, accessibility, and content sourcing.
Will Large Sudoku use copied puzzle books?
No. The site uses an in-house generator and solver so boards can be produced and checked without copying newspaper grids or puzzle books.
Can I print a puzzle and a separate answer grid?
Yes. The print page is for the clean puzzle board, and the answers page is separate so it does not spoil the puzzle sheet.
Will ads interrupt the puzzle board?
No. Any future AdSense placement should stay away from the board, number pad, status panel, and print output.
