The 12Bet mobile app offers live betting functionality that lets users place wagers on ongoing matches in real time. As events unfold, the odds update continuously, and the app displays live scores alongside the bet slip. This feature covers football, cricket, basketball, ice hockey, tennis, volleyball, and many other sports. The cash-out feature is also available on live bets, allowing users to close a position before the final whistle if they wish to secure a return or limit a potential loss.

Casino and gaming options within the 12Bet app include a live dealer casino, slots from leading software providers, table games, and lottery products. The live casino section streams real dealers from professional studios, supporting games like roulette, baccarat, blackjack, and game shows. Slots are sourced from providers including Genesis, Cameplay, eBet, and others, ensuring a wide variety of titles and themes.

Push notifications keep users informed about upcoming events, promotional offers, and changes to their account. The notification system can be customised from within the app settings, allowing users to select which types of alerts they receive. The app also supports multiple languages, including English, Thai, Chinese, and Vietnamese, making it accessible across different regions in Asia and Europe.
