I use bovada for sports betting and noticed their blackjack promo they were advertising. With a $5 bet they give you a $21 dollar bonus for a blackjack one time each sunday. So because this makes the odds +EV I tried it. The play through is a $100 bucks so I did this too and won an extra $100. I would recommend it because if you play perfect here with that extra $21 I believe the edge is the players.
