Printing tips

• Print A4 or Letter portrait and one board fills a page. For 12×12 and 16×16, turn on “Scale: fit to page”.
• Menus and footers are not printed: only the board, the difficulty and the address that opens the same board.
• In the game, the Save as PDF button above the board saves the board you are playing as a one-page PDF with a QR code that opens it on a phone.
