When you join a game of roulette, you usually get a stack of casino chips. Typically, a stack would have twenty chips. In a game of roulette, chips are only valid at your roulette table. You can’t take them with you to a different roulette table, or start playing some other game with them.
This happens because in the game of roulette, the dealer needs to know the owner of the chips. It is not enough to simply have any chips. This is the reason why roulette tables have sets of chips for the table, and you can’t move the chips elsewhere.
The dealer keeps track of the value by putting a marker called a lammer on your coloured chips. Smaller casinos, where players play with chips of the same value, the dealer may not even use lammers. At the end of the game of roulette, when you leave your table, your dealer will exchange your chips for regular casino chips that you can take with you elsewhere in the casino, including other games. Or, if you want, you can take your winnings to a cashier’s window and cash out.
In the game of roulette, the dealer performs a variety of tasks to keep the game going. He or she converts your cash or your casino chips into the roulette chips unique to his or her roulette table. He or she also helps you place your chips on the table if you are not able to reach the squares where you want to place your chips.
The dealer also spins the roulette wheel and releases the ball onto it. Sometimes a dealer spins the wheel while the players are still placing bets. Typically, players may continue placing bets until the dealer says the phrase “No more bets” and waves a hand.
