Sudoku game in C++ using SDL2

Requirements

• Microsoft Visual Studio
• SDL2 and SDL_TTF2 (already included in Dependencies folder)

How to build and run

• Open Microsoft Visual Studio
• Click "Clone a repository"
• Copy and paste respository link
• Compile and run in x86 mode in either Debug or Release
• If you want to run from the generated executable, make sure the dll files and assets folder are copied to the same directory as the executable.

Framework diagram

Key:

• Arrow = inheritance
• Line = composition

• All 81 (9 x 9) cells and the stopwatch act as buttons
• The stopwatch and any cell set to a non-zero value during the generation of the puzzle act as buttons that cannot be clicked
• "New" button generates a new Sudoku
• "Check" checks if attempt is correct

Possible things to add

• Add difficulty setting by changing the number of cells removed in the generator class
• When a cell is selected, highlight the block of 9, row of 9, and column of 9 and show which numbers cannot be placed in that cell
