A Cephoid is an algebraic ("Minkowski") sum of finitely many prisms in ℝn. A cephoidal game is an NTU game the feasible sets of which are cephoids. We provide a version of the Shapley NTU value for such games based on the bargaining solution of Maschler–Perles. The value is characterized by a suitable set of axioms
