Scoring Play Combinatorial Games Under Different Operators
  Scoring play games were first studied by Fraser Stewart for his PhD thesis. He showed that under the disjunctive sum, scoring play games are partially ordered, but do not have the same "nice" structure of normal play games. In this paper I will be considering scoring play games under three different operators given by John Conway and William Stromquist and David Ullman, namely the conjunctive sum, selective sum and sequential join.
