While playing video poker today at Pair-a-dice in Peoria IL (Boyd) a slot tech was doing somthing to all of the poker machines. When he came to mine he stated he needed to turn off all of the double up features. He stated something happened in Vegas last night about midnight and he had to make sure every machine was checked and the feature turned off. It was not good enough to look at the screen, he had to open each machine and turn off the feature no matter if it was on or off. Does anyone have an idea what happened?
