Cheating is certainly not recommended, not legal and in no way endorsed by Gambleversity. But, for the sake of education, this course will deal with ways for a player to cheat at blackjack and the methods that a blackjack dealer may use to cheat the players.

One popular method of cheating is to mark the cards. High value cards such as Tens are the usual marking targets. "The Daub" technique is done by applying a substance that leaves an almost invisible smudge on the card. One scam involved the use of a special paint that was only visible to specially made contact lenses.
