Life game


Introduction

Here is a lattice similar to a chess-board. The lattice compromises of cells in which there are some creatures living (but only ONE creature can inhabit ONE cell.) A cell which is inhabited by a creature is "on" (colored blue) and an empty cell with no creature is "off" (colored yellow).


Rules

Each cell is surrounded by eight neighboring cells. The creatures increase or decrease in the next step according to the following rules:
  • If a cell is "on"
    When two or three of the neighboring cells are "on" , the cell remains "on". In other cases the cell becomes "off".
  • If a cell is "off"
    When three of the neighboring cells are "on" , the cell also becomes "on". In other cases the cell remains "off".
