It has actually gotten slightly worse at the Rivers as the bank of four $1/$2/$5 single line machines across from the Multi-Strikes have been changed to 25c/50c/$1 “All-Star II” format.
All games on these machines are under 97.7% and the $1 games are the same pay tables as the 25c and 50c games.
I have removed AA2005 through AA2008 from the database.
