Nonny lets you play and create nonogram puzzles! Nonograms (also known as Griddlers, Picross, and Paint-by-Number) are logic puzzles played on a grid of squares. The squares are filled in or left blank according to numeric clues at the sides of the grid. When the puzzle is finished, the filled-in squares form a picture.
Nonny comes packaged with a selection of puzzles for you to play, and you can easily import puzzles from other sources. Nonny also allows you to create your own puzzles. There is a built-in solver which can be used to verify that your puzzles have only one solution.
Nonny tracks your completion status and times for each puzzle, and you may save your progress on a puzzle and resume solving it at a later time.

Nonograms are logic puzzles originating from Japan. You start with a blank grid and then fill in the cells according to the clue numbers at the sides. When you finish the puzzle, you're left with a picture to look at:
For example, a clue of "4" means that you need to fill in four consecutive blocks somewhere within that line. By considering the different possible positions you can determine that some of the cells in the line must be filled:
Similarly, a clue of "1 2" means that one cell is to be filled, followed by a gap of at least one blank cell, followed by two consecutive filled cells:
By working line by line in this way, you can solve most puzzles. Harder puzzles may require more advanced techniques, but well-made puzzles should not require guessing.
Nonny also supports multicolor puzzles. These puzzles work the same way, but each clue number is colored to indicate which color the cells must be painted:
Adjacent blocks of cells of different colors need not have a gap between them. For example, a blue 2 followed by a red 2 means that there are two consecutive blue cells, possibly but not necessarily followed by a gap, followed by two consecutive red cells:
Again, by considering the different possibilities you can find cells that must be filled in, which gives you more information to solve the other lines in the puzzle.
Nonny is functional and has a reasonable set of features but needs some optimization and some polish. Other goals for the near future include support for more file formats, better efficiency in the solver, and command-line arguments for easy puzzle loading and solving.
Additional planned features include the ability to save and load puzzle states while solving so that guesses can be easily made or reverted, and a better clue display that makes it easier to see clues for the current row and column when working on large puzzles.
From binary (currently Windows only):
Download the latest nonny-x.x_w32.zip archive and extract its
contents anywhere. You can then run Nonny by running nonny.exe.
From source:
You'll need to have several things installed. First you'll need
general development tools: a C++ compiler (the one provided by the
GNU Compiler Collection works well), essential
binary utilities as provided by GNU
binutils or your system's
equivalent, a shell from which to run commands, and basic command line
tools for working with directories. On
Debian-based systems, you can get these by
installing the build-essential package.
Next, you'll need CMake 3.1 or later, and the
following libraries: SDL2,
SDL2_image, and
SDL2_ttf. Make sure you
have the development headers for these libraries installed. On
Debian-based systems you can simply install the packages cmake,
libsdl2-dev, libsdl2-image-dev, and libsdl2-ttf-dev.
To build Nonny, first download and extract the source archive, or (if
you have git installed) clone the repository with
git clone https://github.com/gkikola/nonny.git
Then from the main project directory (the one that contains the
CMakeLists.txt file), run the following commands:
mkdir build
cd build
cmake ..
This should create the input files for your platform's native build
system. On Unix-like systems this will usually be in the form of
makefiles. You can then run make to build the game and then sudo make install to install it (installing is not necessary, you can run
the game from its build directory). On Windows you can use CMake to
generate a Visual Studio solution, which you can then open and build
within Visual Studio. It should also be possible to build and run
Nonny on macOS or OS X but this has not yet been tested.
