Nonogram Puzzle - Logic Game

This is a totally free APP where you can solve Nonogram puzzles.

Nonogram Puzzle, also known as "Griddler" or "Pixel Puzzles" is a grid-based number game that is equally famous as Sudoku. Nonogram is a logic game that involves creating a black-and-white pixel image through deduction. Players fill in the grid by solving the puzzle. The grid contains a set of numbers at the beginning of each row and column. Players must use these numbers to fill in the squares, with black color for filled squares, eventually revealing a picture.

How to play:

The goal is to discover a hidden picture by marking each square as black or white. You can click on any square. Clicking once will turn it black, and clicking again will turn it blank.

The numbers at the edges indicate how many black squares are in each row and column and how they are grouped together. For example, "2 1" means there is a group of two black squares followed by a group of one black square in that row or column. A group of black squares is always separated by one or more white squares. The same applies to columns.

Therefore, you may observe that if there are seven consecutive black squares in the center column, the middle four squares must be black as well. Thus, you can click on each square to mark them as black.

Press the "Check" button, and if you see red numbers, it means there is a mismatch between the counted squares and the indicated numbers in a row or column. If there are no red numbers, then you have successfully solved the puzzle.

The larger the numerical puzzle, the more challenging it becomes, requiring more intricate logical techniques to solve.
