DESCRIPTION:We consider nonlocal 2-player games which are "unique"\, in th
 e sense that each player has a unique winning answer determined by a refer
 ee's question pair and the other player's answer. We show that such a game
  has a perfect vect-strategy (or quantum strategy) if and only if it has a
  perfect deterministic strategy\, estimate some game values using C*-algeb
 ras and discuss games based on groups\, which generalise the XOR games. Th
 is is joint work with Vern Paulsen.
