Sudoku-Game

C++ Sudoku Game with a Qt desktop interface. The application allows users to generate new Sudoku boards, load saved games and make moves with real-time validation. The core Sudoku logic is independent of the GUI framework.

Features

• Qt GUI
  Difficulty picker, action buttons, bold 3×3 block borders, and status feedback.
• Puzzle generation
  Create Easy, Medium, or Hard puzzles on demand using the bundled generator.
• Live validation
  Prevents illegal moves, enforces number ranges, and resets protected clues automatically.
• Solver integration
  Delegates the current board to the backtracking solver.
• Load & save
  Restore puzzles from Games/ samples (or your own files) and export progress at any time.

Build & Run

The Makefile expects a Qt 6 installation. Point QT_ROOT at the Qt kit you want to use (the path that contains bin, lib, and include).

make QT_ROOT="..Qt/6.10.1/mingw_64" build
make QT_ROOT="..Qt/6.10.1/mingw_64" run

Requirements

• C++17-compatible compiler (Qt 6 requires C++17)
• Qt 6 Widgets module (headers + libraries)
• GNU Make 4.x
• CMake 3.16+ (bundled with Qt; used indirectly by the Makefile)

Built With

• c++
• makefile
