What a sportsbook is
A sportsbook is the part of a casino where bets are taken on sporting events, and in Las Vegas it has grown into a venue in its own right: a theatre-style room with a wall of screens showing every game in progress, a board listing the odds, a counter with tellers, and seating that ranges from bar stools to reserved leather recliners. Every major casino has one. Some, such as Circa's three-storey room downtown and the Westgate SuperBook, are destinations that visitors go out of their way to see; most are a comfortable place to watch a game with a drink whether or not you have money on it.
Nevada legalised sports betting long before the rest of the country, and the Las Vegas books remain the most developed. Betting is legal for anyone 21 or older who is physically in Nevada, in person at the counter or a kiosk, or through the casino's app once you have registered in person. You do not need to be a hotel guest.
Reading the board
The board — now almost always a bank of screens — lists each game with a rotation number (used to identify it at the counter), the two teams, and three main markets. The point spread gives one team a handicap: "Cowboys −6.5" means the Cowboys must win by seven or more for that bet to pay. The moneyline is a bet on who simply wins, priced in American odds: −150 means you stake $150 to win $100; +130 means a $100 stake wins $130. The total (over/under) is a bet on the combined score. Beyond these are props (individual outcomes within a game), futures (season-long results) and parlays (several bets combined for a bigger payout if all win).
The book's margin is built into the odds, most visibly in the standard −110 on either side of a spread, and it is why the house wins over time. This page is about how the rooms work, not about how to beat them; no one can reliably tell you that.
Placing a bet at the counter
Walk to the counter with cash (most books also take casino chips or a players-card account; credit cards are generally not accepted) and tell the teller the rotation number, the bet type and the amount: "Number 305, the under, for $20." The teller confirms the odds and prints a ticket. Keep it — it is a bearer instrument, and a lost ticket is a lost bet. Winning tickets are cashed at the counter, at any book in the same company, or by mail within a stated period. Most books have kiosks that do the same job without the queue, and the casino's app lets you bet from anywhere in the state once you have registered at the counter with ID.
The minimum bet is typically $5–$10 at the counter and lower on the app. Tellers are used to first-timers; if you are unsure, say so and they will walk you through it. On a busy Saturday in football season the queue can be 20 minutes, so bet before the game, not at kickoff.
The rooms worth visiting
- Circa Sports (Circa, downtown) — the largest sportsbook in the world, three levels facing a 78-million-pixel screen, with stadium seating and a bar on every floor. Worth a visit even if you never bet. Also the book behind Stadium Swim, where the pool deck faces the same games.
- Westgate SuperBook (Westgate, off-Strip near the convention centre) — the historic giant, with a 220-foot video wall, huge seating and the widest range of futures and props.
- Caesars Palace — the classic Strip room, recently rebuilt, central and comfortable.
- Bellagio and Aria — smaller, more upscale MGM rooms with reserved seating.
- The Cosmopolitan — a compact, lively book with a good bar attached.
- Red Rock and Green Valley Ranch — the locals' books in the suburbs, with big screens and cheaper drinks.

Big events: Super Bowl, March Madness, fight weekends
On the biggest sports weekends the sportsbook becomes a ticketed event. For the Super Bowl, the NCAA tournament's opening weekend and major fights, the large books sell reserved seats or packages — a seat, a screen, food and drink credit — with prices as of 2026 from roughly $100 to over $1,000 depending on the room and the event; they sell out weeks ahead. The casinos also run viewing parties in ballrooms and theatres. Without a reservation, expect the free seating to be full by early morning and the room at capacity. Hotel rates across the city rise sharply on these weekends too; see best time to visit and our events hub.
Regular-season weekends are the opposite: free seats are usually available, the atmosphere is good and the drink service is generous. A Sunday in football season at any large book is one of the best free things to do in the city.
Etiquette and drink service
- Seats are for bettors in the reserved sections. In the free sections, staff may ask for a ticket on busy days; a small bet secures your place.
- Drink tickets: most books give free-drink vouchers with bets over a threshold (often $10–$25 per drink ticket, varying by book). Otherwise there is a bar. Tip cocktail servers a dollar or two a drink.
- Tip the teller a few dollars on a good win; it is customary, not required.
- Do not stand in front of seated people during a game, and keep the noise proportionate — cheering is fine, abuse is not.
- Photography of the board and the room is usually fine; filming other patrons is not.
- Smoking is allowed in most casino sportsbooks, which can be a shock; some newer rooms are non-smoking.
Apps, ID and the practicalities
Every major operator has an app — Caesars, BetMGM, Circa Sports, STN Sports (Station Casinos), the SuperBook app — and each requires one-time in-person registration at one of its books with government ID and, for most, a Social Security number for tax reporting, which makes some apps impractical for international visitors. Once registered, the app works anywhere in Nevada and nowhere else; it geolocates and stops working the moment you leave the state. Winnings above certain thresholds are reported for tax; the teller will explain when it applies.
If you would rather not bet at all, nothing on this page requires it. The rooms are open to anyone 21 and over, and the best of them are worth 20 minutes of anyone's time. For the wider casino floor, see our casino basics guide; for the bar side of a game day, bars and lounges.
