Casino chips are an important part of the gambling scene and are indeed, iconic of the hobby.
Casinos generally use chips instead of cash in order to easily facilitate the transfer of money. Some casinos even do this to make sure that players can focus on the game instead of the fact that they are potentially losing money at the tables. Beyond the casino walls, these plastic chips are just that - chips, worth nothing. It is inside the casino where they are handed or bought by players where they find their purpose. There are stations specifically for this purpose. Generally the chips come in the form of a small circle, made of out molded clay, steel or any kind of metal or even hard plastic. Casino chips, in general help the players play as handling them is extremely easy compared to bills. It also helps a player keep track of their money easier, as the colors easily correspond to preset amounts.
Slot machine players also have a need for these chips, as machines do not usually take to the quarters or coins anymore, but rather specifically designed chips made to work with the slot machines. It was made to keep players from cheating the slot machines with cleverly controlled coins and as it is easier to play with with.
High stakes games, such as professional Texas Hold'em or any final table situation for poker tends to use gambling plaques rather than chips. Values for these gambling plaques range anywhere from twenty five thousand and higher. Made from the same material as chips, it also helps add a sense of occasion to the game. Casinos make full use of this medium, applying it to every other game as well such as roulette and blackjack.
The colors on casino chips tend to denote the amount that it represent. Casinos may each have their own design, personalized for the owner's sake. Chip sets can also be bought for home use and with the rise of Texas Hold'em, these usually also come with two decks of cards and even a dealer button to make the experience deeper. These usually come in a uniform set of colors, blue, black, green, red and white and it's up to the house to determine its final worth. Depending on the general money involved with the casino, chips can come in values as low as fifty cents or even as high as ten thousand dollars, for the intense high rollers out there.
