Description
In a specific game scenario, you need to manually drag and drop the rock-shaped digital modules and precisely place them at the corresponding positions on the grid. At the same time, fill the entire grid with numbers. During this process, pay special attention to the rules: numbers must not repeat in any row, any column, or any 3 × 3 square area.
When there are already some numbers in the grid, you should use the existing numbers and your logical reasoning skills to determine the position of the missing numbers. To better assist yourself in reasoning and record your guesses, you can also use small stone-shaped markers to track your guesses.
