Put $30+ outright bet on the world cup winner and each time your choose country win, you will receive $5 in term of free bet so basically thats 6 times to win to get your bet back so pick one wisely. Brazil, Argentina and Germany is pretty much the top favourites for now
The upcoming world cup is event for lot of bets and we will see huge wagering around at that time and this new promotion is cool but I would say that you would have to win atleast 6 matches but this will work better if you place multiple bets as it's hard for particular team to win 6 matches.But will see my favourite team to bet upon on this event and spare $30 for it.
