About
Gridworld is an artificial life and evolution simulator. It simulates a 2D, grid-based ecosystem where virtual creatures struggle to survive, adapt, and evolve through natural selection. Watch them learn to find food, avoid danger, and compete to survive. Let them thrive on their own, or step in with world editing tools and scenarios to shape their fate.
Creatures appear as colored tiles with tiny subcells that represent neurons. You can see them move around, eating food to stay alive and eventually reproduce if they are successful enough. Each has a body and a neural network brain encoded in DNA.
Input neurons sense the environment.
Signals pass through the neural network.
Output neurons trigger behaviors such as moving, rotating, reproducing, eating, or attacking.
You begin with a world full of food and randomly generated creatures. Most cannot feed or reproduce, and their genes die with them.
Eventually, one random DNA combination succeeds, resulting in a creature that can eat and reproduce. It multiplies rapidly, sparking a population explosion and the start of evolution.
Don’t have the patience to wait?
No problem, several scenarios with simple premade creatures are available.
These let evolution start immediately so you can focus on watching adaptation and natural selection unfold rather than waiting for the first self-replicating creature to appear.
When creatures reproduce, DNA may mutate.
Some mutations are beneficial, improving survival.
Others are harmful or neutral.
Successful mutations spread, unsuccessful ones die out.
This ongoing cycle of mutation and selection drives adaptation.
Because creatures live fast, you can observe evolution over hours or days, instead of thousands of years.
Evolution happens automatically, you don’t need to guide it.
Start a simulation, let it run, and check back later to see what has emerged.
Want more control?
Use the world editor to create new challenges.
Adjust simulation settings to change environmental conditions.
Intervene during simulations to see how populations react and force them to overcome new challenges.
Over time, many natural phenomena can emerge:
Development of food-finding skills
Emergence of danger-avoidance behaviors
Predatory ambush tactics
Coevolutionary arms races
Temporary multicellular clusters, where creatures combine into larger forms to hunt prey
Population booms and busts
Predator–prey population splits
Speciation, as populations split into distinct species adapted to different niches
Viruses and parasites replicating by exploiting other creatures
Viral outbreaks that can wipe out large parts of the population
Every simulation is unique.
Start your own world, watch evolution unfold, and discover what forms of life will emerge in Gridworld.

One of THE evolutional simulators! This simulation consists of cell sized creatures in a gird, so it is focused on behavioral and "stat" evolution throu a system of neurons (ie. eating neuron, moving neuron, neuron neuron [for more thinking]). Its a bit hard to understand what each neuron does, I personaly have not found documentation for this, but it is mostly intutitive. You can get a lot of fun behaviours and you can really tweak the simulation to great detail. I find the gravity setting to be fun to turn on sometimes, to see all the carcases fall down :3. I hope to see a multicelular species evolve sometime, Hopefully I will be able to see one this patch. I recommend to anyone who likes evolution, ants and little creatures. And unlike Bibites or some other sims this simulation can run more creatures at the same time, thanks to its more primitive physics system (or maybe there is some other reason) so even a potato can probably get some fun creatures out of this. Recommend with a full hearth! [>]w[<]
Pixel grafik yaşam simülasyonu biraz karmaşık bir yapısı var herkese de hitap edecek bir oyun değil çok arada kaldım ama olumsuz vereceğim
É tipo um World Box de baixa renda. Você não tem muita interação com o jogo, ele praticamente faz tudo sozinho, você assiste o desenvolvimento do "planeta" e das espécies (todas de forma pixelada). Você pode alimentar, mover ou matar alguma espécie/unidade em prol de algum tipo de experimento. Existem alguns estágios do mundo que em você pode escolher ou pular para acelerar o processo de desenvolvimento. O jogo em si não há muito o que fazer, apenas assistir as coisas se desenvolvendo por horas. Eu diria que é relaxante, mas nada de extraordinário.
Gridworld, developed and published by DopplerFrog, is a distinctive simulation game that explores the mechanics of artificial life and evolution within a 2D, grid-based environment. The game immerses players in a digital ecosystem where virtual creatures struggle to survive, adapt, and evolve over time. Released in late 2015, Gridworld has earned a reputation for its innovative approach to simulating life, combining simple mechanics with emergent complexity to create a sandbox that both entertains and educates about the principles of natural selection. At the core of Gridworld is its simulation of autonomous creatures, each represented by colored tiles composed of subcells that function as neurons. These neural networks dictate the behavior of each creature, processing environmental inputs and triggering actions such as movement, rotation, eating, attacking, and reproducing. This system allows for the emergence of complex, often unpredictable behaviors from relatively simple rules, giving players the chance to observe evolutionary processes unfold in real time. As creatures interact with one another and the environment, traits that enhance survival are naturally selected, creating a dynamic and constantly evolving ecosystem. The game’s progression is driven entirely by these emergent behaviors. The initial population consists of randomly generated creatures, many of which are ill-equipped to survive. Over time, through mutation and selection, some creatures develop effective strategies for feeding and reproducing, which leads to population growth and the evolution of increasingly sophisticated behaviors. This slow but rewarding process gives players a sense of witnessing life adapt and thrive, emphasizing the intricacies of survival and evolution without requiring direct intervention. Gridworld also includes a variety of tools and customization options that enhance its replayability. Players can adjust simulation parameters, alter environmental conditions, or introduce obstacles to observe how creatures adapt. A level editor allows for the creation of custom worlds and experiments, giving players full control over the ecosystem they wish to study. These features encourage experimentation and creative problem-solving, as each simulation can produce dramatically different outcomes depending on the setup. The visual design of Gridworld is minimalist, favoring function over form to focus attention on creature behavior and ecosystem dynamics. The pixel art style is simple but effective, making it easy to track the actions of individual creatures within the crowded grid. The user interface is intuitive, offering quick access to simulation controls, creature statistics, and environmental settings, allowing players to engage deeply with the mechanics without unnecessary distractions. In conclusion, Gridworld is an engaging and intellectually stimulating simulation that combines the appeal of sandbox gameplay with the educational value of observing evolution in action. Its emergent mechanics, customizable environments, and minimalist design make it a compelling platform for exploring artificial life and natural selection. Whether approached as a scientific curiosity, a creative sandbox, or a relaxing simulation, Gridworld provides a rich and rewarding experience that showcases the fascinating complexity that can arise from simple rules. Rating: 8/10
My worlds are gridding
Si
If you are at all into life simulators, this is an exceptional addition to that genre. The creature design is a little complicated at first but once you understand it it produces some fantastic results and can create some wonderfully interesting evolutionary paths. The terrain system likewise is light-weight but detailed enough for any experiment you wish to run. You can set different ground types to grow different combinations of food, whether they cause damage, whether they hinder movement, whether you can move across it with land or aquatic movement (or even different ranges of each if you wanted to create a swampy area or something of that nature). While it is not something that can be played like a typical game, keeping a notebook nearby and recording a journal of your world and creatures can really satisfy that "Darwin on the Beagle" feeling that I'm always looking for.
Kind of like an aquarium, funny lil fellas.
Grow parasites from thin air. 10/10
It's an interesting game, well it's not a game. It's an "evolution simulator". Where you get to watch pixels evolve into smarter pixels until you get a thriving pixel ecosystem. 7/10
