Large maze
Large here means 20×20 — bigger than Medium’s 15×15, not yet Impossible’s 35×35. The URL exists so “20x20 maze / large maze” searches get a real board, not a blog post about graph paper.
Dead end? Turn around. Don’t blame the wall.
When
When to use
Use this page when you want a bigger walk than Medium without jumping straight to Impossible, or when you searched 20×20 / large maze.
When not
When not to
Phone with a tiny screen and no zoom patience → Medium or Easy. Mythical “world’s largest” → theater elsewhere.
Defaults
Assumptions
Grid locked at 20×20. Perfect maze. Worker carve.
Steps
How
- Land — 20×20 should already be up.
- Walk carefully; more forks than Medium.
- Print if you want the big sheet on paper.
Worked notes
Examples
- Medium cleared too fast; Hard’s 25×25 can wait → 20×20 locked upstairs
- Classroom: one large printable from the same live grid → Print keeps the carve
Watch-outs
Gotchas
- Large ≠ Impossible. Impossible is 35×35 on this site.
- Dense printouts need a steady printer — expect small corridors on letter paper.
- Support wording covers nearby sizes in prose; this URL’s lock is 20×20.
