Card counting is not illegal in casinos in the UK or elsewhere, but if card counters are detected by Casino staff, they are perfectly entitled to request the card counter to leave the premises. Gone are the days when this included a good thumping in a deserted alleyway adjacent to the casino, that has been relegated to the movies, but once you have been ejected from a casino then it is very unlikely you will ever be permitted to return, and in the worst case your details could be circulated to other casinos who might also exclude you.

Card counters are simply trying to increase their chances of winning by determining if the deck is hot; that is if it contains a disproportionately high number of high cards. This is advantageous to the player as it increases the likelihood of a blackjack which awards a good payout. Card counters apply a simple algorithm that allows them to assign a ‘count’ to the cards, and when the count is high, that is there are a high proportion of high cards remaining, they increase the size of their bet. It is impossible to card count online, with online casinos generating random cards every hand.

This new device that has been developed at Dundee University has a stereo camera recording the table activities and the video is analysed by a computer which itself counts the cards. Thus the computer ‘knows’ when the deck is hot.

The camera determines the size of bets by analysing the chips, and can detect any changes to the betting patterns. This simultaneous analysis of the card deck and the manner of betting only needs twenty hands to determine if card counting is going on.

If it detects card counting it sends a message to the casino staff, and what they do is up to them.
