Has anyone completed the current puzzle. Seems like the early pieces have taken a lot longer to get than was the case with prior puzzles - and they have very little reward. I have been very limited in chips since I ran out during the 12 days of Christmas thing. Got a good daily spin today and had a nice run on slots so I have some chips to play with again - but have only just now gotten the 3rd puzzle piece. Is it worth even trying to get the last 3?
