Reordering Numbers Game

This is a transitional reorder of numbers game, Try to rotate the random ordered numbers into 1 to 15 from the top row to the bottom row.
This game will bring your memory back to the Old Good Days. (Of course, the present days are also good.)
OK, just enjoy the game and kill your boring time whenever is needed.
This is the first version and only in the test stage, we will release the working and better version soon.
Bye from now.
