Building an advanced Sudoku game moves beyond the typical 9×9 puzzle by including features like dynamic puzzle generation, automated solving, and variable difficulty settings. Implementing these elements demands algorithmic thinking, as each grid must be carefully validated to ensure accuracy.
Concurrency might come into play if you introduce timed challenges or daily puzzle updates, keeping engagement levels high. Adding hint systems or pencil-mark functionality refines your understanding of data structures and real-time event handling.
You gain deeper insight into advanced Java concepts through these interconnected features while crafting a polished, logic-based game.
