i dont like the post number# one, for one thing its too boring. I like the random one, its definately fair, if done correctly.puzzles arent good, because some people just dont like, or suck at puzzles. now, what i was thinking is that we could find an online blackjack game, we could all play it online multiplayer and have a tournament, the reason for blackjack is that its more like a lucky type game instead of skill, plus its easy to learn, or we could do the one about the one where you pick a game, and we could see who scores highest.
either way really, as long as its fair, and everyone can do it, it should be fine.
