Happy Wheels is one of the most popular bad physics games out there. Bloody, gory, and stupidly fun to play at school or office,
Bloons Tower Defense 5 is hands down the best tower defense game on the web. Great upgrades and a number of challenging maps. Amazing free tower defense game,
Run 3 unblocked comes the best iteration of the 'Run' series. A great twist on the endless runner genre in general. A fun game for wasting time.
Run 2 game not as good as the third, but still a lot of fun. Good controls and very smooth. One of the most fun runners out there.
Age of War 2 game is the sequel to a browser classic. A lot of fun, even if it isn't quite as ground-breaking these days.
1 on 1 Soccer, Certainly soccer, in some form. Not the best soccer game out there by a long shot.
4 x 4 Soccer, Yes, another soccer game. Not bad for a browser game, though.
4th and Goal 2016, A rare flash version of American football. It isn't Madden, but it doesn't try to be. Good game overall.
Ace Gangster, Top-down crime game that's a bit like the original GTA series. Good graphics, but controls aren't great.
Basketball Legends, Fun basketball action. Good for a few games, at the very least. Won't hold your attention forever.
Big Heads Football, Another one of the lovely Big Heads game. The soccer skin doesn't make it any less silly.
BMX Master, Solid bike game. Controls take a minute to get used to, but it's still a lot of fun.
Bubble Shooter, The name pretty much sums it up. Decent time waster with a lot of potential.
Cookie Clicker, Not the first idle game, but perhaps the most popular. Funny, even if it barely qualifies as a game.
Dad n Me Who doesn't like beating up poorly rendered children? An absolute classic.
Dragon Ball Z, Unsurprisingly not a real licensed product. Good enough for what it is, though. One of the best free ways to play DBZ.
Feed Us 4, Make your fish bigger by eating tourists and all peoples you find, Feed your fish, Eat as much as it possible
Football Legend 2016, One of the better soccer games out there. Fun for fans of the sport, if no one else.
G Switch 3, Basically Gravity Guy with a different skin. It's a fun game, but not original. Good controls and great backgrounds, though.
Learn to Fly, Absolutely classic upgrade game. One of the best flight games available.
Mike Shadow, Unreasonably dumb 'fighting' game. One of the best games you'll ever play.
Plazma Burst 2, Fine game, if limited. Looks better than you would imagine.
Super Mario Flash 2, Mario, but in Flash form. Not as fun as the real thing, but awfully close. The closest you'll get to Nintendo in a browser.
Superfighters, Straightforward combat game. Nothing special, but not too bad.
Territory War 2, Good Worms throwback. A fun way to pass time, especially as you get better at the game.
Urban Basketball, Good basketball title. Tries something new, at the very least.
Whack Your Boss, Weirdly violent, but good stress relief. Won't win any awards, but it's fun nonetheless.
Zombie Baseball 2, Use your baseball skills to save the town from zombies. Just as silly as it sounds.
Zombie Demolisher 3, Basically Angry Birds with zombies. A few neat mechanics, though.
Zombocalypse 2, Fight off the hordes with a number of weapons. Remember when Zombie games were still cool?
