It's free to participate but you may never get your free bet even if you correctly predicted results.
I have been dragged with FortuneJack support and email for days like I won five million dollars, and it's really hilarious.

Where you at the top of the list for one of the rounds that guaranteed you a free bet? I am sure it takes a few days for them to update the tables, check if everything was legit, there isn't any multi-accounting and abuse going on before they credit the free bets. Their terms say you will receive your free bets in up to 4 days.
I remember that it took them a lot of time to update and adjust the rankings for their CL JackMate competition as well. But eventually, they'll get there.
I do believe that even though it may came in very late, it still comes in, I remember that premier league goal scorer thing and only time I won, I got it like a week later so it is understandable. The tie thing however in the games is not really cool but everyone does it, it is literally same everywhere, in some places there are extra bets, bets that are 1x2 and there is no draw, but this isn't just the whole bet, there is also one with draw as well, people do want to bet on the draw after 90 minute so that is an option, but there is zero places I know that does no draw option available.
If you really want to go with "whoever goes to next stage" bet then there are other places that do have those kinds of bets along with the draw bet option on another bet, but if you do not mind it then you can play here as well if you think it is not going to end with a draw after 90 minutes. I believe for example Italy will certainly not have a draw.
