A note regarding the odds of winning Blackjack free:

Like all casino games, the odds of winning are slightly in favor of the casino. In our game, we use a cryptographically strong randomizer to shuffle the decks to make the game as authentic as possible. The game of blackjack is not meant to be ‘won’ but is instead a game of both strategy and chance, resulting in both wins and losses. The unfavorable hands are meant to make the following winning streaks that much sweeter :)

Blackjack 21 Rules:

Blackjack, also known as 21, is one of the most popular casino games in the world. Blackjack is a card game where players compete against the dealer. The object of the game is to reach 21 or to reach a score higher than the dealer without exceeding 21.

In Blackjack free by Brainium, the dealer must draw to 16 and stand on soft 17. Blackjack pays 3 to 2, and insurance pays 2 to 1.

Great blackjack app with a very clean layout! Edit: Really, really want more options for the dealer and deck. Having one deck is fine, but it's small and there's a reshuffle after 8-12 hands. The app is fantastic, but a little more options would entice me to play more and make it more difficult (or even a paid option to add more decks). Thank you for making this game, it's a step away from being the best blackjack app on the planet.

Provides exactly what it claims to: a straightforward blackjack experience where everything functions the way it should. There are no frills, the graphics aren't over-the-top, and the app itself runs very smoothly without draining much battery. Ads only occur when you lose all of your chips, and they're very short.

I've played other blackjack games and I think the flow and layout are the best. Ads only required to be watch when you are bankrupt. However, this game forces a losing streak on you to get to $0. I have played about 5000 hands and bankrupted many times, but I am persistent and start over. This last time, using the same betting strategy I always have, I made it to $10,000,000! But now, doing the same strategy that got me there, I am down to $15,000 and I know I will lose that too.
