Review for Diamond Jo Casino Northwood Review For Diamond Jo Casino Northwood Google User Jun 26 '17 at 23:25 Joke.. it used to be fun when all it took was $20 to play and win the entire night on slots but now $20 lasts 3 to 5 mins on slots.. table games are the way to go now money seems to last longer.. as far as the employees and other things goin on its a nice place.. just sometimes seems they have more than enough employees if they have time to stop and watch people playing, and yet other times when a machine malfunctions it takes them forever to get to you to fix the problem.
