Bartok and Mao
As with other combination shedding and guessing games such as Mao, the rules can become quite complex. The similarity between Mao and Bartok is such that the two games are sometimes referred to by the other's name. The principal difference is that in Mao a substantial set of rules is maintained between games, whereas in Bartok this is only true of the minimal initial set of rules. Further, in those variants of Mao where rules are added between rounds, these rules are usually added silently and must be deduced by other players, whereas in Bartok the new rules are told to everyone. This allows the rules of Bartok to be substantially more technical than the rules of Mao, since the details of the rules can be discussed.
