An artificial survival Game for a mass of competing species is introduced and investigated numerically. It is assumed that (1) each species consists of hunting predators. (2) All the species have their own nests to live. (3) They feed on common preys which are distributed in a one dimensional cellular region. (4) Each species randomly attacks a certain number of cells to feed on preys. The evolutional rule of this randomly connected predator-prey network is given in a highly simplified manner as a set of difference equations. An optimizing rule which facilitates the efficiency of the whole system is also included. In spite of its simplicity, this Game is found to exhibit complex behavior, i.e., its long-term behavior is chaotic, or self-organizing, or critical, depending on parameters involved.
