Instructions
Arrange the tiles so that they are in the order of 1-2-3 on the top row, 4-5-6 on the middle row and 7-8-9 on the bottom row. At the start, the top row will contain tiles 8-1-7, the middle row will have tiles 3-6-9 and the bottom row will have 4-5-2, in that order. The #5 "tile" is the empty slot that you move the tiles into. You want to end up with the center tile empty.
String the tiles together rather than try to place each individual tile in its final spot on the grid. Maneuver the #1 tile so it is next to the #2 tile, and then maneuver the #3 tile so it is connected to the #1 and #2 tiles.
Move the tiles as a chain and "snake" your way to the top to place the three tiles where they belong all at once. Use this maneuver on the bottom two rows until you have all of the tiles in place.
