If you don't have a dreidel, you can usually find them in a grocery store (in the Hanukkah section which will be quite small). Safeway and Mollie Stone's carry them. Many synagogue/temple gift shops will carry them and many are open on Sunday mornings during the next few weeks. If that fails, ask a Jewish friend where to find one. Likely that person will be happy to share one of their child's dozen dreidels from home.
Here's how to play dreidel:
-Each player starts out with an equal number of tokens (pennies, M&Ms, chocolate gold coins, etc.)
-Everyone antes up one token into the center.
(the photo on the left has a purple shin and a red hay. The photo on the right has a green gimmel and a blue nun).
-One person spins the dreidel. Depending on where it lands, the spinner will:
- nun - do nothing
- hay - take half the pot
- shin - put one in
- gimmel - take the pot
Everyone antes in again after a gimmel. Play until you're bankrupt (I've been playing a bit too much Monopoly lately), or until you're bored.
Here's a good explanation of the origin of the game.
