All ages can enjoy these games, with something for everyone. The easy levels on some of the activities are simple enough for younger players, but truly torturous on the higher levels. Crosswords and Puzzles , by eGames , is simple in design, but offers lots of standard puzzle fare like word searches, jigsaw puzzles, scrabble, word scrambles and more, which are challenging and fun to play. Another example of eGames puzzles is their Galaxy of Games , which offers 23 card and board games, all for a low price. There are literally 100's of puzzle downloads available, but for brevity's sake, I am only listing some of what's out there currently.
Many sites offer puzzle fun for adults and children, and several update weekly.
Houghton Mifflin's Education place offers a new Brain Teaser each Wednesday, for 3 different grade levels. BrainBashers updates each Sunday, and is a great place for kids to exercise those brains. Definitely for older kids. Great site for the whole family. An excellent site for kids.
