An open frame in bowling occurs when a player does not knock down all 10 pins in a frame and fails to score a spare or a strike. This means that the player leaves at least one pin standing after both rolls of the frame. In an open frame, the player earns the number of pins knocked down, but no bonus points are added. An open frame results in fewer points, making it harder to achieve a high score compared to frames with strikes or spares.
