Nonograph

Nonograph is a nonogram (picture cross) puzzle where every solved grid develops into a real photograph. Use the numbers beside each row and column to work out which squares to fill: no math, just calm logic. 300 photo puzzles across 15 chapters, from quick 5x5 grids to relaxing 15x15 ones, a boss picture against the clock at the end of each chapter, a gallery of every photo you reveal, and a new 15x15 picture every day. A short tutorial teaches the rules if you have never tried a nonogram.
