Besides the rules of the actual game, there also exist unwritten rules of roulette etiquette. Many consider these guidelines as important as the actual rules. Tipping etiquette varies by location, but it is polite to tip the croupier when leaving the table or after any winning number.

Rules related to casino security

• Players are not to collect their winnings and betting chips on the outside chances until all of the winnings in the same box (e.g. all bets and winnings on ‘red’) have been paid. This is to avoid confusion and minimize the chance for players to steal other players’ chips.
• Players must not touch chips after the dealer gives the hand signal or announces “no more bets”. Players are not allowed to remove, change or add bets past this point.
• When the dealer has placed the “dolly” (the plastic marker used to mark the winning number) it is strictly prohibited to touch any chips on a winning chance.
• Dealers are not allowed to take money to change for chips from a player’s hand. If the player wishes to change he or she must place the money on the layout of the table.
• The use of electronic equipment at the table such as mobile phones and cameras is also prohibited.
• The only items allowed in front of a player are: Chips, money, drinks, cigarettes. Bulky items such as wallets and purses or bags must not be on the table.

Commonly observed etiquette

• Players should place chips on the board rather than tossing them. Tossed chips may roll on to displace other bets or roll down to the “chipping machine”. If the player cannot reach to place a bet himself he should announce the bet to the dealer. This is treated as any other call bet.
• Changes for cash or color chips are supposed to be done in between spins. If the dealer has time he will make changes during the spin but he will most likely prioritize call bets before changes.
• All call bets are considered courtesy bets and are only placed if the dealer has time to change and place the bets. The bet is considered taken only if the dealer and the inspector dealer has repeated the bet. If the dealer does not take the bet he will announce “no bet”. To argue with the dealer about which bets have been taken is considered extremely impolite and will most likely render a warning from the inspector dealer or pit boss.
• No food or drink is allowed over the table. Most casinos have a “table fee” that the player is forced to pay if he or she spills on the table layout.
• Upon leaving the table it is considered polite to leave a tip for the dealer, although some casinos prohibit employees from accepting tips.
