A variant of the object redistribution game Bulgarian Solitaire may be defined using rules for pile reduction which vary among piles of different sizes, but remain consistent for piles of a particular size throughout a single game. Such a variant may produce behavior that deviates significantly from that established for the original version. Bounds on maximum cycle length found in such variants are provided, as are conditions associated with cycles of positions which are “isolated,” in the sense that no position outside the cycle leads to any position within it.
