I support this too. A counter displaying the remaining number of bets (sats) to get a golden ticket in the hi-lo game would be a useful feature for many users. So I think if freebitcoin developers wish, they can easily implement such a feature because it shouldn't be a difficult task for them. By the way, if a user has a desire, he can write such a counter (script) himself using the console in a browser, although I'm not sure that would be a good idea because freebitcoin may interpret it as a violation of its rules.
Counting/checking own stats cannot be seen as a 'illegal activity' or anything like that. But I do not want to write my own scripts for a feature which seems to be a very simple/basic for a given functionality. It would be really good to have a simple progress meter which would give information like '45% to the next GT'.
