Does this have any Replayability? Or once you solve it can you always solve it in just a few minutes?

I would say it depends on how good your memory is. For me, once solved, mix it back up and let sit for how ever long you would not remember what it took to solve it.

What happens when you solve it? Does it lock? Does something detach?

A great euphoria washes over you. 😐

The description says "material: plastic" then later in the description says "solid wood puzzle". Which is it?

I bought two and both were wooden. If the pic shows wood and you do not get a wooden puzzle, then return it but make sure it says returnable.

Is there a hidden compartment in this to put money or something in? I want to get something for Christmas for my kids. But if there isn't a prize at.

No and hopefully your kids are at least teenagers because this is not an easy puzzle. Still working on mine! There is one or more of these puzzles with a hidden box. I think it might be Pandora or Emperors chest.....
