| Abstract: | This paper introduces the conceptof \pi-balanced multi-choice NTU games and proves that any \pi-balanced multi-choice NTU game hasa non-empty core. The definitions of non-leveled multi-choice NTU games and reduced games are introduced and theconcepts of consistency and converse consistency are also given. An axiomatization for the core ofnon-leveled multi-choice NTU games is provided by using individual rationality, one-person rationality,consistency and converse consistency. |

| Keywords: | multi-choice NTU games cores \pi-balancedness consistency |
