It is largely legal in Las Vegas for adults 21 or older to carry and drink alcohol from open containers in public. You also may bring open containers into casinos, but they can lawfully ask you to leave unless you dispose of the alcohol. Meanwhile, driving with an open container in Nevada is always a crime.

In the vast majority of major casinos, especially in Las Vegas or Atlantic City, you are absolutely permitted to walk around the gaming floor with an alcoholic beverage. In fact, many casinos provide complimentary drinks to active players to encourage them to stay at the tables. You can carry your drink from the bar to a slot machine or take your "to-go" cocktail from one casino to another as long as you remain within the designated "open container" zones (like the Las Vegas Strip). However, you generally cannot bring outside alcohol into a casino, and you must always have a valid ID. In 2026, some boutique or "family-oriented" regional casinos may have stricter "dry" zones, but the classic casino experience remains one where a drink in hand is the norm.
