From what I’ve seen of the game I would imagine the spinner spins the wheel and when the camera zooms in and stops, the spinner presses a button at the Monopoly podium at the right hand side of the screen that ends the round and sends the winning number to the casino. I’d expect the spinner pressed the wrong button and that’s why they soon swapped spinner.
The spinner goes to the podium just after releasing the spin as well, might be to close betting?
At least there is video proof, I’d expect there to be refunds soon.
