Two places that I like to practice my blackjack.
The first is cloudbet. You can play for free or put money on the line by playing with bitcoin. I like to play for free, I am not good enough yet T playing for money.
The second is GSN. This website is from the popular Game Show Network. You can play for free here. Plus you can collect oodles sometimes just by playing games. You can use the oodles to enter sweepstakes to win real money and prizes. I won a $25 Amazon gift card.1Nc9iPQ9ZvzPLU49T1haVtBhoVU4thWpjS
