Blackjack is the most widely played casino banking game in the world, in which cards are compared between one or more players and the dealer.
Players compete against the dealer, or the house, and not against each other. It is, thus, easy to understand that they cannot actually win easily. And it has been a game of percentages and edges which has puzzled and drawn people for ages.
The game is so old that its first written reference was more than 400 years ago in a book by the Spanish Miguel de Cervantes, himself a gambler, the same author who wrote Don Quixote. The card game is so popular that it has even a Hall of Fame.
It can be played in brick-and-mortar casinos, but also in online casinos, where playing blackjack live can be done from virtually everywhere in the world, on your mobile device. In fact, more and more people choose to play cards on their mobile devices.
But how to win at blackjack?
Of course, there are many ways. One is the more you play, the more you gain experience. Then you can learn blackjack odds and strategies. And there is also the method of card counting, even though casinos will not be happy with that.
Now it may seem harder to understand quantum physics than blackjack, but here is what quantum entanglement is about: A physical phenomenon which occurs when a pair or group of particles interact no matter how long the distance. Furthermore, they can communicate their states with another one instantaneously.
And there is a simple way in which players can win at blackjack using this principle: That is if all the players at the table would work as a team. This way, they would communicate covertly between each other regarding the cards which have been dealt to them.
This is how the players can gain advantage over the dealer as a team, estimating which cards are still in the deck, which are most likely to be drawn, and thus what bets to place. It’s like a quantum computer working to beat the dealer.
In fact, this way of winning at blackjack has been used for decades, being made famous by a group of students from MIT, along with Harvard and Caltech. They inspired the book “Bringing Down the House” and many other players since 1979 – that is around 15 years after physicist John Bell proved mathematically that quantum entanglement could exist - till the beginning of this century. The method was also made popular in the movie “21”, with Laurence Fishburne and Kevin Spacey.
Now back to the game – the students based their theory on the fact that all the cards dealt to each player are correlated. By communicating with each other, the gamblers would focus on a sole player at the table to effectively know the decisions of the others – for example, whether he or she will pick a third card or not.
While the advantage of the players in this case is just a slight one in front of the card-counting strategy, and the method is not welcomed in the casinos, it sparked a lot of imagination for blackjack players and fans.
However, quantum entanglement and quantum computers won’t be used in casinos, so the best way to win at blackjack is to play it, enjoy it, and try the best to beat the house.
