The birthday girl or gal might not technically be old enough to play the slots in Las Vegas, but that doesn't mean they can't play a few hands of cards at his or her sweet 16. The casino theme is a great option for the girl or gal that loves to play cards. After you've decorated the room and picked the perfect tableware and favors, you can enlist family members to play the dealer at a few different card games around the room. Guests can go around and play the games. Instead of using real money, simply give each guest an allotted amount of poker chips. Once they run out, they can earn more by doing favors for the birthday guy or gal or playing other games.
Since dice are such a big part of casinos, they make for an obvious tool in portraying your theme. Just for the night, make 16 the lucky number and play every game with 3 dice. Get a few Giant Dice and turn them so that they add up to sixteen and continue your decorating merriment all throughout the venue.
