If there is a red box it means that it is “circled” and the amount you can bet is reduced. A line can be circled when factors besides the game play are considered e.g., injuries or weather conditions The outcome of the game could affect. Circled lines can’t be added to a parlay,as many bookmakers don’t have enough information on the game and can’t accurately balance the action as it comes in. For most sportsbook businesses their model involves trades to balance and protect the bottom line. For many sportsbooks it is important to have their lines un-circled. The red box is usually removed just prior to the start of the game.
