MATERIALS
- A 4x4 sliding tile puzzle frame with fifteen numbered tiles and one empty space
HOW TO PLAY
1
Start with the tiles scrambled out of numerical order within the four-by-four frame.
2
Slide any tile that is adjacent to the single empty space into that space, shifting the empty space to where the tile used to be.
3
Continue sliding adjacent tiles one at a time, planning moves ahead to avoid disrupting tiles already placed correctly.
4
Work to arrange the tiles into numerical order, typically reading left to right and top to bottom.
5
Leave the empty space in the bottom-right corner once all numbered tiles are in their correct positions.
6
The puzzle is solved when every tile reads in order and the empty space rests in its final position.
