The 20×20 is the nonogram marathon: 400 cells and clue runs that fill the margin. The key is staying systematic — sweep the rows, then the columns, and never guess. One grid can fill an entire evening. On hard, the grid is sparse: every cell is earned, the back-and-forth multiplies, and the advanced techniques — overlap, edge logic — earn their keep on every line.

Printing tip: letter or A4, portrait, default margins. Tick “Include solutions” to get the answers on a second page — handy to fold away for later. Prefer a screen to a pencil? The same format is playable online here, and the basics live in the beginner guide.
