Nonograms or picross - these are puzzles in which you need to solve color or black and white images by given numbers.
Each number represents one horizontal or vertical block. The number indicates the number of cells in each of them, color - respectively the color of cells. Between blocks of the same color must be at least one empty cell.
Found empty cells can be marked with crosses (right key, or select crosses in the color panel). Under the crossword puzzle there are many options that help set up the solution process.
You can easily search for resolved and saved Nonograms in the catalog. Crosswords that you do not want to see in the lists (except the "any status" filter) can be added to the black list.
A variety of pictures can be encrypted in nonograms! People, animals, plants, objects, anything!
The whole nonogram solution process consists in sequentially finding filled cells and empty places that cannot be exactly painted analyzing alternately horizontal and vertical. The more cells you label, the more new leads you have.
Consider the solution to a small nonogram.
First of all, we look for the largest numbers on the left or top, and best of all at the very edges, it is easiest to start a solution with them. In the last column we see the number 6. This means that the column has one block of 6 cells filled in black in a row. Since the Japanese crossword is only 8 cells high, this block in our case can be located in three ways - adjacent to the upper edge, to the bottom and in the middle. If you take two extreme positions, it becomes clear that the cells below will be painted over anyway.
Now look at the two horizontal lines with numbers - 5. Each of these lines has a block of 5 cells. Thanks to what we found one filled cell with an edge for each, we know exactly how these blocks are located. Feel free to paint. Useful feature: holding down the CTRL key you can immediately paint over a whole rectangular block.
The program will automatically cross out the numbers that are found correctly and put the crosses in free cells. This feature can be disabled in the settings, if you want to control the whole process yourself. In this case, crosses can be set with the right mouse button, or by choosing crosses in the color panel. In addition, the settings you can adjust the appearance of the crosses, the color and transparency of the backlight, and much more.
Now pay attention to the fourth line. It has a pink block of two cells. Looking at the top numbers, we see that pink is only in two columns, so the horizontal block can only be located in the following cells.
In the third column above the pink cell should be a block of three cells. Since there are only three empty cells left there, it means that we definitely know its position.
The second line should be a block of three cells. One filled cell is already there, and it is bounded by a cross on the right side. This means the block can be continued only in one direction, we paint over it.
We apply similar techniques to the remaining cells and get the finished picture, the nonogram is completely solved!
