ABSTRACT
Since we are still concerned with impartial games, in this chapter we shall call our players Arthur and Bertha rather than Left and Right Now there are many different ways in which Arthur and Bertha can show off by playing several games against each other simultaneously, so as to make a single com pound game. Throughout much of this book we have been concerned with the disjunctive compound, when the compound move is defined to be a move in just one of the component games. Tn this chapter, we shall add some other systems of rules, so as to make in all a round dozen of different ways of playing several games at once.
