Slide puzzle question

I don't know about the 9 puzzle but I suspect it's like the 15 puzzle. The
15 puzzle and Rubics Cube have parity. If the 15 is out of parity it can
never be solved. The same for Rubics Cube, if you say switch 2 edge pieces
or rotate 1 corner piece it's not solvable.

Hi there,

I am making a 9 piece slide puzzle.
How many pieces should be in the right place at start to solve the puzzle?



greetings,

William
