Cell Lab: Evolution Sandbox Description: WARNING: Cell Lab is a very challenging game that requires lots of thinking and experimenting. Reading the instructions will be necessary. If you enjoy difficult simulation puzzles then this is for you.

Cell Lab simulates few-celled organisms. It contains 45 challenges where the player is presented with an environment and has to design an organism that will survive in it. Solving challenges unlocks additional genes that can give cells new properties.

The encoding of the cells behaviour has been made as intuitive as possible without losing generality but it nevertheless takes a bit of effort to understand. Going through the provided tutorials carefully is recommended.

Cell Lab also contains an experimental mode where the user can set the parameters of the environment and put designed organisms in it to see how they multiply (or die). It is also possible to seed this environment with random genomes and once a viable genome has been seeded one can see how it slowly evolves through tiny mutations to an organism well adapted to the environment it is in.

It is then possible to change the environment to see how they re-adapt, fast forward the simulation, and finally to save and share it.

This simulation is not biologically realistic, all cells in Cell Lab only has one function, to swim, to eat, to collect sunlight, to float, etc . This is not how cells work in nature where one cell can do many things at once. This accuracy has been traded off to be able to make an interesting game. The cells have also been made to multiply very fast, this also for the enjoyment of the user.

What is realistic is the evolution taking place in this game. How species adapt to their environment and compete with each other to sometimes attain an equilibrium and sometimes extinction.
