How to quick select numbers on multi card keno

[ManiacalDabMan]

Can anyone tell me how to quick select the same number on all 20 multi card keno cards?

There is no quick way to do it. It's too bad they don't have a button that lets you pick all the cards at once, that would be nice.

You have to finger every number over and over and over again. My advise, don't put your finger in your mouth when you're done!
