PUZZLE TIPS AND HELP

Well I would like to create a puzzle in my game (I'm using VX).
Since I have no experience with that whatsoever... I'm asking here.
Does anyone know of a already made puzzle that includes freeing the player from his ropes(He's tied up).I thought like having a special lock on his shackles(optional)that would be moved around like a boulder puzzle.I don't have a idea how to do this however.Or I could make something like having the player move his ropes against something(left - right).Don't have a idea how to do this too.

Thanks in advance,
Milos
