Popcap.com has a free online game of 8 Ball, which some might simply call pool. It’s a fairly easy to play, yet challenging game against the computer. You break, then start trying to clear the balls off the table against the computer, leaving the 8 ball for last. It shows you how hard you are hitting the ball (the scale at the bottom) and what angle you’re hitting the cue ball and whatever ball it is aimed at. Great for learning the angles. And if you notice at the bottom right, you can even program in some “English” to hit the cue ball off-center to help with tricky shots.
If you fail to hit one of your balls in, the computer gets a turn. The computer isn’t a great player, so if you aren’t either, this game will be fun. If you are a really good player, you may get bored fairly quickly. You learn the rules of the game, even regarding scratches. The computer keeps score, though ultimately it’s really down to you clearing the table of the stripes of solids before the computer does.
