This Sudoku game is an interactive web-based puzzle that allows players to solve Sudoku grids at different difficulty levels. Players can select preset difficulty options—Easy, Medium, or Hard—which determine the number of prefilled cells. Additionally, users can manually customize their challenge by choosing the number of cells removed from the grid. The game is designed to be intuitive, responsive, and engaging for both beginners and experienced Sudoku enthusiasts.
The goal of Sudoku is to fill a 9x9 grid with numbers 1-9, ensuring that:
- Each row contains every number from 1-9 exactly once.
- Each column contains every number from 1-9 exactly once.
- Each 3x3 subgrid contains every number from 1-9 exactly once.
- Select Difficulty: Click on Easy, Medium, or Hard to generate a prefilled Sudoku grid with a varying number of missing cells.
- Custom Challenge: Alternatively, use the custom difficulty option to select how many cells should be removed for a personalized challenge.
- Start Solving: Click on any empty cell and input a number between 1-9 to begin solving the puzzle.
- A number cannot be repeated in the same row, column, or 3x3 section.
- If you enter an incorrect number, you can erase it and try again.
- The puzzle is completed when all cells are filled correctly.
