Absolutely, and live betting is becoming increasingly popular. Live betting is a great way to get involved in a game where you didn't have a strong lean before it began. If you are watching a basketball game and one team starts shooting exceptionally well, the in-game total will inflate and there may be an opportunity to play the under with the hope that the hot shooting won't last all game. If you are watching a baseball game and the starting pitcher continues to get out of jams even though he's getting hit, that might be an opportunity to take a look at betting the over with the hope that those hits will eventually turn into runs.
