Navigating the incredibly complex, unwritten rules of social etiquette on a bustling casino floor can be highly stressful for a first-time visitor.

Tipping, commonly referred to in casino slang as "toking," is not strictly legally mandatory, but it is deeply ingrained in the culture of the gambling industry.
Tipping the Table Game Dealers
There is absolutely no strict mathematical percentage required (like 20% at a restaurant), but a general rule is tipping $5 for every hour of standard play.

This creates a fantastic, cooperative atmosphere, as the dealer is now actively, financially invested in your hand winning alongside you.
Always tip the dealer in casino chips, never attempt to hand them physical cash currencyIf you hit a massive progressive jackpot on a table game, a 1% to 3% tip is considered standardTip the dealer even if you are losing slightly, as they have absolutely no control over the cards dealt Tipping for "Free" Casino Drinks
However, while the physical alcohol is technically free, the service provided by the incredibly hard-working cocktail waitress is absolutely not.

If you fail to tip the waitress on her very first delivery, she will likely completely ignore your section of the casino for the rest of the evening.
Tipping on Massive Slot Wins
If you are incredibly lucky and hit a massive slot machine jackpot exceeding $1,200, the machine will lock up and require a "hand pay."

If you hit a staggering multi-million dollar progressive jackpot, a flat tip of a few thousand dollars distributed among the attending staff is highly appropriate.

Tipping is the ultimate grease that keeps the massive, chaotic gears of the physical casino machine running smoothly and pleasantly.
