I've had hot cycles, very rare at Mystic Lake, and many many cold cycles. I see the replies from the casino manager on these reviews and it now makes sense about the hot and cold cycles. I've been to Ho Chunk casinos, Peppermill in Reno, Treasure Island, etc.
I've been playing Keno for a long time, I love Keno machines, it is really all I play when I go to any casino.
