I'm less than halfway through, but does the lottery not exist in this...
Couldn't they have just put up the Powerball numbers one time and then moved away forever? When they first found the machine and they talked about the track winners I was like what? Of course a bookie is going to get suspicious if you win every bet.
It's an interesting premise and I'll finish watching it because I have nothing better to do, but that's a huge plot hole. They were worried about the space time continuum, but could have avoided it by just putting up Powerball numbers one time. Nobody thought, "Hey the lottery exists."
