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.
Casinos hosting a slot tournament would require players to participate by paying a fixed entry fee called a buy-in.  The entry fees can range fromR$25 toR$100, and these payments contribute to the cash prizes in the competition. Certain casinos might ask players to sign up to receive an invitation to participate.
