These are the Ten Play $1 8/5/60 Super Aces near Bingo.
The machine now rejects anything over $400 inserted. I know that may sound like a lot or money to those of you playing lower denominations. But for a $1 Ten Play machine you have to have a substantial bankroll.
The machine also now stops and automatically prints out a ticket every time your credit balance goes over $400. (If your credit balance is $370 and you hit one full house in 10 hands, the machine now pauses to print and issue a ticket for the $40, leaving your balance at $370).
By limiting the credit balance this game is in effect slowed down substantially. You are also now frequently loading up the machine with cash or tickets. Doing this quite conspicuously in view of other players may be a security concern for some.
