Across Rows, Columns and Diagonal the Magic Sum is 15 . All through out the filing the same horse is used, but in Step 3 and Step 6 reverse horse is used as the cells were already filled.
Fill the 1st number in the centre of the upper most row. (We can start from any cell.) Choose suitable horse and move from the 1st number to 2nd number .
Again with the same horse to the 3rd number sand so on.. If we will have to move further from right extreme, start counting the rest of the leap from left extreme of the same row and complete the jump.
