If you already know the rules of the game please
click on "Hide Help" above in order to close the instruction box.

Choose a level from 3 until 10. Level 4 has been
pre selected.

The playing area contains 15 numbered squares.
There is an empty square that enables the others squares to move.

The purpose of this game is to put the numbers
in a series in the shortest time and with as few moves as possible, using the
empty square for temporary moves.

Your time starts as soon as you press the "Start
Game" button.

You can move a square by clicking on it. This
can only be accomplished if there is an empty square next to it.

You can move an entire row or column of squares
by clicking on one of the squares. This can only be accomplished if there is an
empty square in that row or column.
