It\u2019s one of the oldest clich\u00e9s in the world of casinos: The house always wins.<\/p>\n

Except it doesn\u2019t.<\/p>\n

For more than a decade, a team of card counters based around the Massachusetts Institute of Technology (MIT) proved that the house could be beaten.<\/p>\n

They came up with, and put into practice, a method for winning at blackjack.<\/p>\n

The idea came from the studies of Edward Thorp, a math professor at MIT, who devised a card counting<\/a> system in the 1950s using the earliest computers.<\/p>\n

The team\u2019s success inspired a 2008 movie, 21<\/a><\/em>, starring Kevin Spacey (above), and a best-selling book Bringing Down The House<\/a><\/em>.<\/p>\n

But who were these guys? How did they do it? And could their methods still work today?<\/p>\n

The MIT Blackjack Card Counting Technique<\/strong><\/h2>\n

The first thing to make clear is that card counting is not actually illegal \u2013 as long as you are counting in your head. It is a form of advantage play<\/a>.<\/p>\n

Nevada state laws, for instance, specifically prohibit card counting using electronic or mechanical aids.<\/p>\n

However, legal though it may be, it\u2019s fair to say that you won\u2019t win many friends among casino owners if you practise the art successfully.<\/p>\n

The simplest way of describing the \u201cHi-Lo\u201d method used by the MIT blackjack card counting team is as follows. You count the high and low cards that have been played since the last shuffle.<\/p>\n

You\u2019ll need to have memorized a value assigned to all cards in a deck:<\/p>\n
