"For those of you who have been held hostage in a shed for 18 years and were only recently freed, 1v100 is a gameshow that originated in the Netherlands and was hosted by Bob Sagat in the US. 1v100 pits the "one" against the "mob" in a series of trivia questions. The goal is for the "one" to outlast the "mob." If a member of the mob gets a question wrong, he or she is out. As more mob members fail out, the cumulative prize pool increases. At certain intervals the "one" can puss out and take accumulated prize dollars or continue to try to strike out the mob. If the mob wins, they split up the prize pool.
On Xbox Live, the game takes two forms. Most nights, it is simply a massive trivia game pitting people against each other in thirty minute sessions, with many nights themed. However, on Fridays and Saturdays, the game follows the gameshow format and features a live host, often with guests. The live game is, of course, what makes 1v100 incredibly entertaining and not just a silly group trivia exercise."
