WHAT IS A NONOGRAM?
Nonograms — also known as picross, griddlers, hanjie, nanograms, picture cross, Japanese crosswords, or paint-by-number logic puzzles — are grid-based challenges where you use number clues along rows and columns to fill cells and reveal a hidden picture. No guessing required. Just pure logic and elegant deduction.

Invented in Japan and popularized worldwide through Nintendo's Picross series, nonograms have become a beloved brain training puzzle for puzzle lovers and crossword fans alike. Whether you call them nonogram, nanogram, picross, pic cross, picture cross, griddler, hanjie, pixel puzzle, picture puzzle, paint by number, color by number, or Japanese crossword — Nonogram Zen is your premium destination. Looking for a Nonograms Katana, Logic Pic, or Konami Picross alternative? You'll feel right at home here.
