nbsudoku

nbsudoku is a lightweight, interactive Sudoku puzzle game designed for the command-line interface. Built using the ncurses library, it provides a text-based graphical interface for playing Sudoku directly within your terminal emulator. Users can navigate the grid, enter numbers, clear cells, generate new puzzles, and even reveal the solution. Its simplicity makes it a quick and accessible option for Sudoku enthusiasts who prefer a minimalist, keyboard-driven experience without needing a full graphical desktop environment. It's often included as an example program within ncurses-examples or similar ncurses development packages, showcasing the library's capabilities for creating interactive terminal applications.

As a terminal-based application, nbsudoku requires a compatible terminal emulator. It does not offer features like saving game progress, undo/redo history, or varying difficulty levels directly through command-line options. Interaction is purely via keyboard inputs within the game's interface.

Once launched, nbsudoku is controlled entirely via keyboard:

• Arrow keys or h, j, k, l: Navigate the grid.
• 1-9: Enter a number into the selected cell.
• 0, ., or Space: Clear the selected cell.
• s: Show the solution to the current puzzle.
• n: Generate a new Sudoku puzzle.
• q: Quit the game.
• ?: Display brief help (if implemented in specific versions).

nbsudoku is commonly found in Linux distributions as part of the ncurses-examples or ncurses-bin package. It can usually be installed via the system's package manager (e.g., sudo apt install ncurses-examples on Debian/Ubuntu, or sudo dnf install ncurses-examples on Fedora).

nbsudoku is typically distributed as part of the ncurses-examples package, which contains various small programs demonstrating the capabilities of the ncurses library. Its primary purpose is to serve as an illustrative example of how to build interactive applications with a text-based user interface, rather than being a standalone, extensively developed game. Its presence reflects the utility of ncurses for creating simple, functional terminal games.
