There are a few ways to bet the Facebook Messenger basketball game, but the most common is to use the app’s built-in betting feature. To start betting, open Facebook Messenger and type in “bet on basketball” into the chat box. From there, you can choose between three different games: the regular season game, a playoff game, or a championship game. The regular season game is the most popular option because it’s always available and there are usually several games available at once. The playoff game is also popular because it offers a chance to win money if you win all of your matches. The championship game is only available if there is a winner and it’s usually more expensive to bet on this game than any of the other options.
