The security features of casino chips are numerous. Artwork is of a very high resolution or of photographic quality. Custom color combinations on the chip edge are usually distinctive to a particular casino. UV markings can be made on the inlay. Certain chips incorporate RFID technology, such as those at the new Wynn Casino in Las Vegas. Maker's marks, such as Paulson's top hat and cane, are also difficult to reproduce. Each casino has a unique set of chips, even if the casino is part of a larger company. This distinguishes a casino's chips from others, since each chip and token on the gaming floor has to be backed up with the appropriate amount of cash. In addition, with the exception of Nevada, casinos are not permitted to honor another casino's chips.
Counterfeit chips are rare. High levels of surveillance, along with staff familiarity with chip design and coloring, make passing fake chips difficult. Casinos, though, are prepared for this situation. According to one report, a Canadian casino removed all chips from the gaming floor and replaced them with new sets with alternative markings, which resulted in the arrest of the attempted counterfeiters. All states require that casinos have a set of chips in reserve with alternate markings, though they may not be required to have exactly the same number of reserve chips as they do on the floor.
Casino chips used in tournaments are usually much cheaper and much simpler in design. Because the chips have no cash value, usually chips are designed with a single color (usually differing in shade or tone from the version on the casino floor), a smaller diameter, and a basic mark on the interior to distinguish denominations; however, at certain events (such as the World Series of Poker or other televised poker), chips approach quality levels of chips on the floor.
Read the Pay Tables and this will absolutely give an idea about the frequency that the machine returns a winner. If you see that there are a lot of combinations that return smaller wins, then this machine will usually have a larger hit frequency than one that has fewer captivating combinations that pay back larger wins.
