When you press the New button, the tiles will be re-arranged.

The objective of the game is to move the tiles around the board so that you achieve the initial pattern as above.

Moving tiles

Tiles are moved by pressing any tile in the row or column containing the gap, i.e. the square with no numbered tile.  This tile, together with any tiles between it and the gap, will slide one square along in the direction of the gap, so that the gap is filled.  A new gap will, of course, appear where the pressed tile was before.

Example: Given the following board layout

9
2
5
4
13
7
10
1
6
15
11
3
14
12
8


pressing on 10 would cause the following layout to occur

9
2
5
4
13
7
10
1
6
15
11
3
14
12
8


whereas pressing on the 7 would give you:

9

FAQ

Q. I can't solve the puzzle.  How can I be sure that the tile re-arrangement is one that can be re-arranged to form the target layout?

A. The tiles are not laid out at random.  The shuffling is carried out by making many moves starting from the initial layout, in the background.  This guarantees that the target layout can be achieved.
