Utilizes a backtracking algorithm to generate a complete solution and then removes cells according to the selected difficulty to create a unique, solvable puzzle.
As players fill in the blank cells, the game immediately highlights any errors (duplicate numbers in a row, column, or 3x3 subgrid).
The grid is sizable (630px square) for comfortable play on desktops and scales properly on mobile devices using CSS Grid and media queries.
A timer records the gameplay time, and buttons are provided for starting a new game, resetting the current puzzle, and viewing a detailed Help modal.
