It's the Friday before Christmas weekend. Stop pretending you're trying to get any work done today. Your boss is either off on vacation already or has her feet up on the desk, waiting for the appropriate hour to sneak off for a "late lunch" and never come back. To help you in your final hours of pre-holiday work, I compiled a list of some addictive online games, easy to play but hard to master. Have hours of fun. Go on, you deserve it.
Line Rider - You know it, you love it. This is the new version, just released.
Winterbells - Jump a bunny from bell to bell.
Finger Frenzy - How fast can you type the alphabet? (My high is 8.54 seconds. (Slow typer.))
Sober Santa - Steer drunk Santa away from the rails.
Falling sand game - Part game, part physics experiment.
...and many more.
