Nonograms appeared at the end of the 20th century and became popular all over the world. They are also known as Japanese crosswords, Japanese puzzles, Griddlers, Paint by Numbers, hanjie etc.
Japanese crossword is a very popular puzzle game. 
In the Nonograms, unlike conventional crosswords and arrowwords, a picture instead of words is conceal by means of numbers.
Please have a look at these black-n-white Nonograms. They are divided into several groups by resolution depending on the crossword width and height.
If you like Philippine puzzles, you will definitely like Nonograms too.

All Nonograms have their own single solution.

The grid is formed by horizontal and vertical lines. Numbers on the top and on the left show the sequence order of blocks of filled-in squares horizontally and vertically correspondingly. The blocks are unbroken, and two nearby blocks must have at least one empty (unfilled) cell in between.
The blocks follow one another exactly in the order shown by the corresponding numbers.

Nonograms are solved in the following way:
– First, you need to determine which cells are to be filled;
– Second, you need to determine which cells cannot be filled: these are marked with crosses.
This process is repeated until the crossword is solved.
