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.

Игра Жизнь, но с другими правилами, по залипать, но не более
I didn't play this game enough to truly grasp it, but releasing a major update on a quality, niche 10yo game deserves a thumbs up
Best showcase for the limitations of Java I have ever seen. 10/10
This is the most complete evolution simulator that I have seen so far. It can simulate single and multicellular life, has systems for both asexual and sexual reproduction, allows you to tweak just about everything, and even lets you export raw data to text files so you can make graphs and better analyze their behavior. The most off-putting thing to me about this game was the harsh colors that come with the default style. But I found that you can customize just about every single color in the game, so I made an aesthetically pleasing island map to evolve my creatures on. If you're interested in evolutionary biology as well, pick up this game. There's so much to play around with and experiment with. I have a lot of ideas for future simulations I want to run.
Gridworld. this was the first evolution simulator i ever stumbeled across. cost $2.95 AUD. i was so impressed i started buying aritifical evolution games on steam and looking at online evolution simulators. after playing good evolution simulation games like the bibites and shallow visual focoused games like the sapling and ecosystem i have collated an opinon on this game. of the evolution simulators avalible, I belive this the best of the best. depth of evolution is deep. learn from nothing: a grid is not the dragonborn, it appears usless and dies because it didnt know how to move or eat. eventually one spawns that randomly has what it takes to survive and reproduce. from there ACTUAL behavour emerges. visually, the grid lifeforms are represented beautifly with a pixel pattern dictated by its parts and makes them easy to track, follow and actually understand what you are seeing. no late game frame drop. when the population inittaly explodes, it can drop to a slow point but this is very temporary as the population stabelises itself. the only thing i want that this game dose not have is cloud saves. otherwise this is best artifical creature evolution simulator avalible to date. proud to own this one!
great game love it im the guy who likes these ive collected litterally all evo games i can find since there arent many this one is amazing it has that flare and although i litterally have zero idea whats going on im slowly learning i just had my first succsesful species i call them beavers since they look like them also because they work together like beathers making chains but im pretty sure the food shortage and overpopulation caused most to die in quick sucsecion but thats the beauty of it letting them learn oh and finnally can someone tell me what membranes are also a quick idea it runs smoothly but autosaves take a bit
Incredible evolution simulation that's loaded with unlimited possibilities. Unfortunately, it's written in Java and badly optimized so exploring even basic possibilities will take hours or days, when a well-written simulation in a lower-level language would take seconds, so a thumbs down for Java.
The best evolution sim I've found, especially if you like some more advanced tinkering.
still the best life sim ever
A simple little thing, well worth the low price. Kind of like Species (Artificial Life Real Evolution), if you've seen that before, except it's more lightweight so it doesn't burn your computer in the background, and the lifeforms that you start with on the default setting aren't even guaranteed to be able to eat or procreate. I set up a fairly lethal environment with continually spawning random life, and it took over ten hours before one evolved that could sustainably thrive. I got home to find one of the quadrants almost devoid of plants, totally colonised by a species that doesn't even avoid the lava and is too stupid to turn around when they hit the wall. They spend their entire life moving in a single direction, but they're prolific and energy efficient enough that they birth their offspring at a 90 degree angle, so that the species can continue in a direction away from the obstacles in front of them. They're oblivious, but they're opportunistic scavengers, eating any detritus they come across (even each other, if they sweep along an obstacle where the others are stuck). And they just evolved like this. It's beautiful. EDIT: Only a few hours have passed. A subspecies has emerged that is capable of [i]surpassing[/i] a one-tile-thick lava wall, spread into the adjacent quadrant, so it's now a ring species separated by one that is swift enough to vault the lava barrier. Incredible.
