Question
I just purchased a Bally 742 slot machine. I understand you can adjust them to be "looser". Are there any instructions out there that can show me how to do this?
Thank you, Greg

Answer
Hi Greg,

Sorry my friend, but contrary to this information that has been out there forever, this is just not true. In order to change the payout percentage of a slot machine it is a complicated Job. If you wanted to tighten up the machine, then that is another answer, and much easer to do with the use of bugs, grafts, disk plugs, and reel tape patches. To change the odds you need to change the reel disks and the reel tapes. The reel disks would have to be punched out to match the new reel tapes depending on the percentage of the set of three reel strips you were going to use. These disks are bolted on the side of each reel and can be removed much easer from your model Bally 742 then the old mechanical machines. If you really wanted to try this, my guess would be to get in touch with a slot machine graphics company like maybe Peppers in Las Vegas and see if they have a kit of reel strips and disks for your model and game type with a higher payout percentage then yours. If the game is different, then you have to change all the award glass to match your new reel strips and disks. Its a big job that most anyone would not want to try as there would be a large cost for these new parts also.

Thank You
