Place the numbers currently on the rack on the right hand side of the screen, onto the board on the left in such a way that each row, each column and
each main diagonal adds up to the same value.
To place a number just click on the required number on the rack and then click where you want to number to go on the board.
If a number already exists on the board in that position then it will be returned to the rack on the right hand side.
To reset the board just reload the page
Good Luck
PS: There is no save facility on this one, when you close the page all the current entries are lost :-)
