Video Summary

In a given Sudoku puzzle, you must fill each number from 1 to 4 only once in each row and column. To solve which number belongs in the gray cell, the puzzle requires completing the second row showing results of operations (2 and 1 columns need a 2). Once each potential row and column are solved as per remaining numbers, for the first row, missing numbers reveal that the only number to finalize the position in the upper right corner is 3. Thus, Patrick places 3 in the gray cell, making the correct answer C, 3.
