Hi, a simple Bingo caller with two screens to be used as I did, connected to a TV from the PC, the called screen is dragged onto the TV so players can see what has been called, it's a simple program with a lot of repetitive coding, I'm sure some of it could be minimised but I couldn't find a way and it works very well so I left it alone, it was used in my pub when we were open and enjoyed by many.
