The dealer will place a token on top of the dealer's stack of that color of chips to indicate the value. When a player purchases chips he gets his own color and the value of each chip is the buy-in divided by the number of chips received. The roulette table comes with six to eight sets of different colored chips, each set consisting of 300 chips.
This actually is the true definition of a chip, one which indicates its value is technically called a check. One difference between roulette and all other table games is that roulette chips have no value denomination printed on them.
If you want something more stimulating or with a decent return I would suggest looking at other games. If you are looking for a easy to understand and slow paced table game, and are willing to sacrifice on the house edge, then you may like roulette. As usual the easier a game is to understand the greater the house edge, and roulette is no exception. Roulette is one of the easiest games to play and understand in the casino.
