The Game Of Life Online

The Game of Life is not your typical computer game. It is a cellular automaton, and was invented by Cambridge mathematician John Conway.

This game became widely known when it was mentioned in an article published by Scientific American in 1970. It consists of a collection of cells which, based on a few mathematical rules, can live, die or multiply. Depending on the initial conditions, the cells form various patterns throughout the course of the game.

The Game of Life features a new, unique and much-anticipated multiplayer mode. Online matchmaking lets you play in a whole new way online. Hyper Life is an online Kids game, it's playable on all smartphones or tablets, such as iPhone, iPad, Samsung and other Apple and android system. Hyper-Life is an interesting arcade game. You will run on the live track from a baby. Every level will ask you some important questions. Chapter 1: The Game Most people consider life a battle, but it is not a battle, it is a game. It is a game, however, which cannot be played successfully without the knowledge of spiritual law, and the Old and the New Testaments give the rules of the game with wonderful clearness. Jesus Christ taught that it was a great game of Giving and Receiving. This is an implementation of Conway's Game of Life or more precisely, the super-fast Hashlife algorithm, written in JavaScript using the canvas -tag. It can simulate the largest known patterns, including the Tetris Processor (0.1MB, 29201m cells), Caterpillar (2.5MB, 11m cells), Gemini (1.4MB, 846k cells), Turing Machine (0.1MB, 252k cells).

Rules

For a space that is populated:

Each cell with one or no neighbors dies, as if by solitude.

Each cell with four or more neighbors dies, as if by overpopulation.

Each cell with two or three neighbors survives.

For a space that is empty or unpopulated

Each cell with three neighbors becomes populated.

The Controls

Choose a pattern from the lexicon or make one yourself by clicking on the cells. The 'Start' button advances the game by several generations (each new generation corresponding to one iteration of the rules).

More information

In the first video, from Stephen Hawkings’ documentary The Meaning of Life, the rules are explained, in the second, John Conway himself talks about the Game of Life.

The Guardian published a nice article about John Conway.

The game of life is the best-known two-dimensional cellular automaton, invented by John H. Conway and popularized in Martin Gardner's Scientific American column starting in October 1970. The game of life was originally played (i.e., successive generations were produced) by hand with counters, but implementation on a computer greatly increased the ease of exploring patterns.

The life cellular automaton is run by placing a number of filled cells on a two-dimensional grid. Each generation then switches cells on or off depending on the state of the cells that surround it. The rules are defined as follows. All eight of the cells surrounding the current one are checked to see if they are on or not. Any cells that are on are counted, and this count is then used to determine what will happen to the current cell.

1. Death: if the count is less than 2 or greater than 3, the current cell is switched off.

2. Survival: if (a) the count is exactly 2, or (b) the count is exactly 3 and the current cell is on, the current cell is left unchanged.

3. Birth: if the current cell is off and the count is exactly 3, the current cell is switched on.

The game of life is a totalistic cellular automaton, and can be implemented as follows using the built-in command CellularAutomaton, where the initial conditions are specified as a binary matrix and the results for generations through are returned. (Here, corresponds to the initial pattern.)

Weisstein gives an extensive alphabetical tabulation of life forms and terms.

A pattern which does not change from one generation to the next is known as a still life, and is said to have period 1. Several still lifes are illustrated above. The numbers of still lives of cells for , 2, 3, ... are 0, 0, 0, 2, 1, 5, 4, 9, 10, 25, 46, 121, 240, 619, 1353, ... (OEIS A019473).

Patterns that cycle through a set of configurations are called oscillators.

Conway originally believed that no pattern could produce an infinite number of cells, and offered a $50 prize to anyone who could find a counterexample before the end of 1970 (Gardner 1983, p. 216). Many counterexamples were subsequently found, including guns and puffer trains (illustrated above).

A life pattern which has no father pattern is known as a Garden of Eden (for obvious biblical reasons). The first such pattern was not found until 1971, and at least three are now known. It is not, however, known if a pattern exists which has a father pattern, but no grandfather pattern (Gardner 1983, p. 249).

Amazingly, life is a universal cellular automaton, in the sense that it is effectively capable of emulating any cellular automaton, Turing machine, or any other system that can be translated into a system known to be universal. The outlines of a proof for life's universality were given by Berlekamp et al. (1982) and independently by Gosper (Gardner 1983, pp. 250-253). Around 2000, a Turing machine that can be extended to a universal Turing machine was explicitly implemented in life by P. Rendell (Rendell, Adamatzky 2001). While Rendell's machine can be made into a 'true' universal computer simply by making his tape infinite, he neither noted this fact nor provided an actual construction of a universal Turing machine. Subsequently, on November 11, 2002, P. Chapman constructed a life pattern based on D. Hickerson's 'sliding block memory' approach that implements the actions of a universalregister machine. Unlike the finite tape of Rendell's Turing machine, the values in the registers of Chapman's machine are unbounded, making it a true model of universal computation in the game of life. Chapman's construction uses live cells in an area of , and can calculate approximately 20 generations per second on a 400 MHz computer.

More amazingly still, as shown by Wolfram (2002), even one-dimensional cellular automata(in particular, rule 110), can be universal.

Two-dimensional cellular automaton games similar to life but with different rules have been constructed and given the names HexLife and HighLife. HashLife is a life algorithm that achieves remarkable speed by storing subpatterns in a hash table and using them to skip forward, sometimes thousands of generations at a time.
