Here is one of the older sliding puzzles:

You have a sliding puzzle that looks like this:

AB
 C
DE

You may move a block with a letter on it to the blank space by sliding it there. How many moves does it take to put D where E is and E where D is at the same time? (The other pieces don't need to be in their original spots.)

Move 4 is an illegal move.  You can't slide a block diagonally.
