The 1 vs 100 video game show on Xbox Live typically reserved for Gold members will be free for everyone on Xbox 360 live this weekend.
From today through Sunday, June 28, Silver Xbox Live members get access to the trivia game which pits Xbox members against one another in a game-show like setting.
The show, which hands out real prizes, gave away a car last weekend. I've played the beta once so far, and my whole family ending up pitching in to help with answers. It was a surprisingly fun family game.
