About Nonogram
Nonogram, also known as Picross or Griddlers, is a deceptively simple logic puzzle that's endlessly satisfying to solve. Each row and column has number clues telling you how many squares to fill and in what order. Use pure deduction to figure out which cells are part of the hidden picture and which are blank — fill the correct squares and mark the rest with an ✕. Fill a wrong square and you lose a life, so think before you click. Grids start small and grow as you solve more, making every puzzle a fresh challenge. Calm, clever, and perfect for sharpening your brain.
