Sports betting (also called sport booking) is legal in many U.S. states, including Nevada. This new status as legal for betting on sports is good news for fans of the sport. While has blocked the majority of betting on sports in online and in person, Nevada has recently passed legislation that allows operators of sports books to offer online wagering. The process for booking sports bets was once a lengthy one that involved physically traveling to a book operator for sports. Now, with the help of sports betting apps users can place bets on the go and make payments and bets while on the move. These apps function as digital clearinghouses for payouts and bet calls.
