Bingo Buy cards automated

[login to view URL] is a bingo site, from midnight to 7am the run a free game once an hour and on fridays from 9pm to midnight. What i'm looking for is a small program that will buy the maximum cards for the free games, instead of doing it manualy. So the program will work as follows. I start the program and open [login to view URL] and when a free game comes up, the program will choose max cards and then click buy. I would think this would be a pretty small program. I think it would be best if you joined [login to view URL], (It's Free) and whatch how the free games work so you will know how to build the program. I'm not trying to get anyone to join or anything. I just think you need to see how the free games work in order to build a program.
