You can play Pro Billiards alone on a stopwatch or with other people on the same device in order to experience a contemporary take on the classic game of pool. This game gives you the opportunity to play two different variations of 8-ball pool, which is widely considered to be one of the most popular pool games in the world. The game is played according to the same rules as the modern version of 8-ball billiards. Keep a close eye on the angle of your shots, and only let go of the ball when you feel the force of the shot is just right. The cue balls should be used to pocket all of the balls. Remember to put the final eight balls in the pocket.
