Manhattan is being turned into a giant playground this weekend for hopscotch, cell phone spying and cat-and-mouse games, as part of the annual Come Out And Play Festival.

The Times Square Alliance organized various games held throughout the city and set up a giant white igloo in the middle of Times Square, seen above, so participants can have a place to cool off.

This year's three-day festival features at least 35 games.

"We're playing 'Kiki's Intergalactic Party' or something like that," said participant Lisa Zwick. "We're supposed to go around find clues. One of them was face paint. We're still supposed to find a costume. Basically a bunch of clues will let us into a party at the end."

The games take place from Friday to Sunday, from 4 p.m. until 1 a.m.

Similar festivals have been held in other cities around the world, including Amsterdam and Honolulu.
