Marked playing cards have a long history of use as a poker cheating device, but they don’t always work. Luckily, the casino industry has gotten better at tracking and catching cheaters, so marked cards aren’t in use as much these days. But even in regulated casinos, card cheaters are still coming up with new and imaginative ways to cheat.
There are several different types of markings that a deck can have, including juice-marking, tintwork or shade, and daub. Each of these techniques is designed to give the reader a little more information than just the number and suit of a card.
Juice-marking involves printing the deck with lighter/darker ink, and these markings can only be seen when someone is trained to read them, which requires a filter sunglasses that only show the darker areas. These are often referred to as “juice” decks, and they’re the most common type of marked playing cards used by card cheats.
Tintwork or shade, on the other hand, involves using a tint solution to mark the backs of cards. These markings can be more difficult to see and are usually based on a pattern that changes depending on the back design of the card being marked.
This is a technique that can be surprisingly effective, especially when done correctly. It’s also a great way to fool other players into thinking that you’re not really sure what you’re doing.
The best part about using this technique is that it’s very easy to do. Just look at the backs of any deck and you’ll probably be able to see some of the markings, even if you don’t have the right sunglasses on.
Another option is to use a special daub that has been made with light reflective chemicals. This is a very effective and cheap method of marking cards, but you should keep in mind that this method is not recommended for people with sensitive eyes or people who are playing poker on a regular basis.
In addition, these types of markings are not effective if you’re wearing contact lenses. They can also be contaminated by bacteria, which can cause irritation and eye damage.
The best marked decks for poker cheating are the ones that have been specially processed to make them difficult to recognize by normal means. This will give you an edge over other players at the table, and help you win more money.
