Here you can see 15 squares which
having numbers,and one blank square.
You must have to arrange these squares
in order.That is, the first row must
be 1,2,3,4 ,second 5,6,7,8 and so...on.
You can use four number keys for moving
these squares.For upwards movement
use '8'.Downwards '2'.Right '6',
and left '4'.
It will be more convenient for you,
if you are using number keys on
your right side.Along with number
keys there are 'arrow' signs which
shows four directions.
