Soft Page Background

Every Slitherlink puzzle here is generated and verified inside the app, so no AI is needed for the puzzles. This helper is only for making an optional soft background image. The prompt below is built from your current setup and copied to your clipboard.

How Loop Prints Works

1
Create. Click Create and choose one puzzle or a full book. Pick a grid size from 5 by 5 to 9 by 9 and a difficulty. The app builds a Slitherlink puzzle that has exactly one answer, checked by a built-in solver before it appears.
2
Design. Use the right panel to set the paper size, margins, theme, dot and loop styling, spacing, borders, background, and fonts. Edit the title and instructions right on the page.
3
Manage. Reorder, hide, or remove any page from the Pages list on the left. The answer key stays matched to the puzzles.
4
Export. Download a print-ready PDF, PNG images at up to four times size, or a ZIP of every page. Nothing carries any branding.
