It's really fun! It's mostly like regular hide-and-seek, but with some special rules. You go down to a crowded place - usually downtown, hence the name - and then you start a game of hide-and-seek. But since there are more places to hide, the game is harder, so there's extra incentive. If you find your partner within ten minutes, you get three wishes from them. Fifteen minutes and you get two. If it takes you longer than twenty minutes to find them, you get one wish. When you decide to stop playing, the one with the most wishes gathered up is King!
