The game "Life" is defined in a strict sense and three candidates for three-dimensional versions are presented. One of these versions can be structured to contain an infinite number of parallel two-dimensional universes, each of which allows for the evolution of Conway life objects. Various oscillators are described, and a few interesting collisions between translating oscillators ("gliders") and other objects are mentioned.
