Official betting is the act of placing a wager on a game or event with a licensed bookmaker. It is considered to be the most reliable form of sports betting and offers bettors greater peace of mind and security. However, it is important to note that there are some restrictions placed on what can be wagered. These restrictions are designed to protect the integrity of the games and the reputation of sportsbooks.

The official rules of baseball prohibit any player, umpire, club or league employee or agent from accepting a bribe to fix a match. The rules also state that anyone who violates the code is permanently banned from professional baseball. This is in reference to a 1919 betting scandal between the Chicago White Sox and Cincinnati Reds, in which professional gambler Joseph Sullivan paid eight members of the team (Oscar Felsch, Arnold Gandil, Shoeless Joe Jackson, Fred McMullin, George Weaver, Charles Risberg, and Claude Williams) around $10,000 each to throw the series.

Nevada remains a popular option for sports betting, with in-person wagering available at Caesars properties throughout the state and a handful of retail locations offering online and mobile wagering. New Hampshire was another early adopter, with a limited number of online and mobile sportsbooks going live on March 10, 2023. DraftKings and FanDuel were approved for temporary untethered Category 3 sports wagering operator licenses, while WynnBet, BetMGM, and Caesars also hold tethered sportsbook licenses in the state.
