Slider Puzzles Here are two digital versions of an old and familiar puzzle. They work just like the real deal. Slide the tiles around the grid until you get them all in order. You might find one puzzle is more challenging than the other.      Tiles move toward the empty slot when you click on them. To move more than one tile at a time, click on the top of the stack you wish to move.      You win when all tiles are in the correct sequence, or the picture is complete. To replay, click on the finished puzzle. To wimp-out and auto-solve the puzzles, move the empty slot to the lower right-hand corner and click on it.
