Does Casino Have Marked Cards?
Numerous casinos alter their decks of cards that they sell to tourists. They do this by punching holes in the middle or trimming their edges to prevent cheaters coming back to the table after buying cards and then slipping favorable cards into their hands.
However, even with these security measures in place it is possible for players not to mark their cards without the knowledge and permission of game protection personnel or casino security.
There are many different types of marking methods, but the most common is block-out work, which involves changing the designs on the backs of the cards by removing lines and patterns. Others include cut out work, scrollwork and shade.
Additionally, some marked cards can be read by touch while others are only detectable by hidden cameras and sensors.
Some of the more sophisticated systems use combinations of patterns, colours and shades on the surfaces of cards to allow the user to identify a card even when it is not visible to the naked eye.
A marked card user will mark cards by placing them in a certain position if they have a clear idea of what cards they should mark. This can help them determine if they are playing a winning hand or when to fold.
There are also various other methods that can be used to mark cards, such as scratching them, pricking them with pins or bending them slightly. Using these methods to mark cards in a casino can be dangerous because they are easily replaced and the risk of being caught can be high.
You can also mark a card by removing the back design entirely, also known as damaging or cutting the cards. These marks can be used to cheat a player, but they are not as effective because they are only visible by someone who is skilled in detecting them.
These methods are inexpensive and easy to use, but they are not necessarily the most effective way to cheat at the table. Cheating during high-volume sessions is more likely to be caught and lose money.
These are all possible ways to gain an edge over the casino. These methods should be considered when a game seems uncertain.
David Whitehill, a poker dealer, discovered a marked card scam at an Indian Reservation casino in California in September. This was the first major wake-up call for the casino industry about the need to tighten security in casino card manufacturing plants.
The Whitehill card marking incident is a great example of how casinos can use it to keep their players honest as well as detect collusion amongst their partners at the tables. It is important to train all game protection personnel in the recognition of marked cards. These tells include betting with a first-card edge, using hole card knowledge to modify basic blackjack strategies and varying from standard betting patterns for casino games.
