The games have not been selected yet. No admission fee for the tourney, just pay coin drop which is $0.75 a game. I believe they will be open at 11 if you want to get there early and practice. Might want to call to confirm those hours 405-789-9846. I have not heard mention of a side tournament.
When the main tourney starts, you get only one try on each of the 8 tournament games. Your score will be recorded and ranked on each individual game, and you will be given points (1 point for each player you finished above) for each game. Then your 8 games points will be totaled and compared against everyone else's total points for your finishing position.
