How to use

1. Open this page via the top navigation (Download), or use a link with parameters like ?difficulty=easy&id=1. If omitted, the page defaults to easy/1.
2. The board and tray are rendered in read-only mode for verification and printing.
3. Click the “Print Board” button. When the browser print dialog opens, adjust the scale/zoom manually to your preference.

Print tips

• Paper: A4 is fine for home printing; A3 offers a larger board.
• Orientation: Portrait first; try Landscape if your board is wider.
• Margins: Prefer Narrow or Borderless to maximize the printable area.
• Scaling: Use the print dialog to manually set the scale. Smart auto-sizing and layout optimization will arrive soon.
• Color: Print styles force accurate colors; select Grayscale if you need to save ink.

What’s included

• Board: grid, region outlines, labels and target numbers.
