Players sit at the machines they were randomly assigned during tournament registration. When the tournament timer begins, everyone in the session hits the spin reels button and/or the bonus pop-ups on their machine and plays for the duration of the countdown.
While there are betting strategies for slots and tips to manage your bankroll and potentially increase your chances of winning, there is no strategy that can consistently beat the odds in the long run. Slots are games of chance, and outcomes are random.
