Bowman 2

I thought that I would bring to your attention the best shooting game out there (that you can play for free online without having to wait for any significant amount of time): Bowman 2, at http://www.addictinggames.com . The game is incredibly simple: shoot an arrow through the head of your opponent, or just hit him enough times with arrows to various parts of the body, and you win!

All you need to do in the game is choose whether you want to play against a computer player, a human buddy, just practice with targets, or hunt birds. Playing against a computer player can be pretty rewarding, and there's no chance of him cheating. When you're playing with a friend, on the other hand, you might want to cover his or her eyes so that he or she cannot see the trajectory of your shot, which would allow him to almost automatically win the game.

Practicing is pretty boring and useless...but Bird Hunting is fun! There's no score or time limit: just point at the myriad of birds flying through the sky and fire away! This is something I find particularly fun to do when I'm bored out of my mind, as it requires little to no effort at all.
