Microsoft has confirmed that the new massively multiplayer interactive game, 1 vs.100 will be available for free to all Gold members this Spring.

1 vs 100 Live is based upon the US TV game show and we'll be able to win real prizes based on skill and participation. Currently, it's due to be released in the US only, but if successful may be available in Europe at a later date.

The game's rules are identical to the game show's: A question is posed, and both the single contestant and members of the "mob" must guess at the answer. If the contestant gets the question wrong, the game is over and the prize money is split up amongst the mob. If the contestant gets the answer right, members of the mob who got the question wrong are eliminated, and the value of each question goes up for the solo player as the mob thins out. The contestant can opt to quit with their winnings at any time, or press their luck and continue on.

A release date has yet to be announced.
