What this site is and who makes it
Online Nonogram is a free website for playing nonogram puzzles in the browser. Statika AS, a company based in Norway, builds and runs the site. You can reach the team at kontakt@statika-as.com.
How the puzzles are made
A generator creates each puzzle from a random seed. A line solver then checks the puzzle for a single, correct solution. This proof means the game never asks you to guess. The same seed always creates the same puzzle, so a shared link stays permanent.
