DESCRIPTION:We consider nonlocal 2-player games which are "uni
 que"\, in the sense that each player has a unique 
 winning answer determined by a referee's question 
 pair and the other player's answer. We show that s
 uch a game has a perfect vect-strategy (or quantum
  strategy) if and only if it has a perfect determi
 nistic strategy\, estimate some game values using 
 C*-algebras and discuss games based on groups\, wh
 ich generalise the XOR games. This is joint work w
 ith Vern Paulsen.
