SudokuGrid uses a library of validated puzzle models and mathematical transformations to generate different Sudoku grids.<\/p>\n\n
The transformations preserve the uniqueness of the solution and the difficulty characteristics of the original models.<\/p>\n\n
Each generated puzzle is based on a model selected from the corresponding difficulty level.<\/p>\n\n
Game saving<\/h4>\n\n
SudokuGrid automatically saves the current game using the browser's localStorage feature.<\/p>\n\n
Saved information includes the puzzle, entered numbers, pencil notes and selected gameplay options.<\/p>\n\n
When visitors return using the same browser and browser storage, they can resume their previous game.<\/p>\n\n
Saved games are stored locally in the visitor's browser, not in the WordPress database.<\/p>\n\n
Clearing browser storage or using another browser or device may prevent restoration of the saved game.<\/p>\n\n
Error checking<\/h4>\n\n
Players can enable or disable live error checking.<\/p>\n\n
When enabled, SudokuGrid compares entered numbers with the puzzle solution and highlights incorrect entries.<\/p>\n\n
Pencil notes are not checked against the solution.<\/p>\n\n
Performance<\/h4>\n\n
SudokuGrid is designed to minimize unnecessary server activity.<\/p>\n\n
Public assets are loaded only when the Sudoku shortcode is used, and puzzle generation is performed on demand through WordPress AJAX.<\/p>\n\n
The plugin separates public gameplay from administrative tools to avoid loading the puzzle auditing engine unnecessarily during ordinary page visits.<\/p>\n\n
Actual performance depends on the hosting environment, WordPress configuration and visitor activity.<\/p>\n\n
Privacy<\/h4>\n\n
SudokuGrid does not require visitors to create an account.<\/p>\n\n
Game progress is saved locally in the visitor's browser using localStorage.<\/p>\n\n
Puzzle generation requests are processed by the website's WordPress installation.<\/p>\n\n
SudokuGrid does not require an external Sudoku generation service.<\/p>\n\n\n
