I haven’t posted any games in awhile, but this should make up for it.  Ludobox has over 2,000 games, so there’s no doubt you’ll find a way to waste your time.  The puzzles section is probably the best place to start, since you might as well use your brain a bit.  The game I was up until 2AM the other night playing was Governor of Poker, which confirmed that I shouldn’t be opening an online gambling account any time soon.
