The *4x4 magic square puzzles* is solved by finding the values that make the sums all rows, columns and diagonals equal to the same value. ... The normal variations of these puzzles (in other words, 4x4 puzzles that contain only 1-16 in their cells) have a magic constant of 34 no matter how the numbers are arranged.
*Solutions: 平衡法*
Sum= 1+2+3+..+16
=(1+16)x16/2
=136
Average=136/4=34
