Examples includes cracking the bowling lane by throwing the ball too high, destroying equipment in the stadium with your javelin spear or disturbing the bird sitting on the top bar of the football goal.
Get some rest
After playing for a longer while an icon appears on the screen suggesting you take a break from playing to prevent strains or injuries.
