Linguistics Challenge Puzzles! (Difficulty ranging from green circles to double black diamonds...Friday fun for all!) [more inside]
Bored on your summer vacation? Well, the US government has lots of fun stuff for kids to do on line. Learn fascinating facts about cows (and agricultural marketing!) from the Department of Agriculture. Take a ride to Money Central Station with the Bureau of Engraving and Printing. If you live in a federally-funded housing project, HUD wants you to learn more about being a good citizen. Want something more action-packed? Help FBI Special Agent Bobby Bureau go undercover, or become one of America's Crypto-Kids at the NSA. Play thrilling puzzle games or visit the world's most secret museum at the CIA. Play more games or become a Disaster Action Kid at FEMA! And no list of government kids' pages would be complete without revisiting the children's art contest from the ATF, which I've linked to before...
What do you get when you mix a fiendishly difficult and addictive puzzle game with the feel of a hack & slash RPG set in a cartoonish, slightly tongue-in-cheek fantasy world? That would be Deadly Rooms of Death (DROD for short). The game is freakin' huge, with 25 levels filled with unique rooms, and it also happens to be free.
Go problems database with a slick web interface. Go is one of the most rewarding games I've ever played. You can play games at ItsYourTurn.com, who also have a nice rule summary.
