To prevent scratching the cue ball in billiards, make sure to hit the cue ball cleanly and accurately with the cue stick. Avoid hitting the cue ball too hard or at an angle that could cause it to jump off the table or scratch. Practice your technique and aim to improve your control over the cue ball to minimize the risk of scratching.
