Row Slide Puzzle

In this game there is a picture chopped into tiles and the tiles are shuffled. You need to move the tiles to get back the original picture. Each time you move, you need to move an entire row or column by sliding the row or column. The faster and the fewer moves you make, the higher your score.

Slide the tiles to get back the original picture!

Basic Steps

This game is quite similar to Rubik's Cube, but it is a lot easier. Basically we should finish the puzzle row by row.

For ease of illustration, we label the tiles as follows:

You shouldn't have any problems finishing the first row:

To move the 5 to its correct position, follow the procedure: move down, move left or right, move up:

Do the same to move the 6 to its correct position:

Now you cannot do the same for the 7, because you will disrupt the 5 and 6. All we need is to modify the procedure slightly:

Follow similar steps to finish all the rows until there is only one row left:

Follow similar steps to finish all the rows until there is only one row left:

We should swap the tiles in the last row until we finish. Suppose we arrive at the following situation:

Now we swap 15 and 16 first. Use the following formula:

Use a similar trick to swap 13 and 14 and we are done.
