Players throw 5 dice and make 2 pairs with the results, leaving 1 die as a reject. The 2 pair sums are marked on a score sheet and the reject noted in a separate column (players will end up with 3 'reject' numbers). This continues with players trying to get multiples of their existing pair combinations. They only begin to score when a combination has been thrown 5 times. Play continues until one of the reject numbers has been used 8 times. That player is then out. When all players are out scores are totaled.Einstein is a later version of Choice.Online Play http://saftsack.fs.uni-bayreuth.de/~carador/choice/play.html (Java) - BoardGameGeek
