I would suggest to stay away from any game with a single machine in the casino but it is OK if your local casino is a small one and has only around 100 slot machines. My local has four machines for this game and setup to be dead (not active) for 2 - 3 weeks and active for 1 - 2 days. Thanks and good luck to you!
Every casino setup is different. My local (Winstar) Keep this game so tight for 2 -3 weeks then easy it for 2 -3 days and I got the advantages since I'm almost there every day and could keep track on which set is hot.
