Cardhalla

[1] Near the end of the convention attendees are invited to throw coins at the city to destroy it.

On Saturday night at 10:30, all are invited to help destroy the city that takes the four days of the convention to build.

The winning entrant decided to invite everyone back to throw coins at the city.

A couple of people began to build little towers out of cards while waiting for one of their friends to finish a game.

As that Friday night progressed more and more was added on including bridges and tall towers.

The name stuck and the next year, 2000, Cardhalla became an official event of Gen Con, and was designated space within the tournament hall.

In 2006 the first offshoot of this event was seen at Phoenix ConGames where 30,000 cards were used to build, donate, and destroy.
