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.

4/10
I am 32 years old. My ex-wife and I have a daughter together, and we adopted our son together. Both are now 4 years old. When we were going through our separation, I felt lost and unhappy. I was self-destructive. One day, I was so angry with everything spiraling out of control that I punched a concrete wall in a moment of overwhelming emotion. This resulted in breaking my fifth metacarpal in my right hand—the hand I worked with, played games with, and used to carry my children to bed—the hand I desperately needed to ensure I could continue providing. Upon learning the severity of the self-inflicted damage, I became almost suicidal. Keep in mind that just a few months before this, I was the happiest man, with no history of depression or anxiety. I had never experienced anger outbursts, nor was I the type to break down and cry, but I was in a tough situation that truly prevented me from seeing the light on the other side. With nothing better to do, I looked for a game I could play WITH ONE HAND while recovering. Somehow, I stumbled upon this game and read some of the comments. I decided it was worth a try... I must admit I didn't beat the game, nor did I play as much as some of you. In fact, I may have played this game for only a day or two. That being said, after doing so, I had a new joy and hope for life. I managed to leave behind the pain and suffering that had been thrust upon me. I could experience the joy and happiness of other people. I relaxed for 5 ♥♥♥♥ minutes listening to this music, long enough to realize that I would be okay. After realizing this, I turned off the game and went back to work. My hand hurt a lot, but I was motivated. I stopped feeling so sorry for myself and became the father I needed to be at that moment, not the weak boy I was behaving like. Today, I am close friends with the mother of my children. We don't fight, argue, or say hurtful things to each other. We are parents and friends. Now I have 3 children. My third child is, wait, ALSO 4 YEARS OLD. The woman I am with was going through a very similar situation at the time of my separation, and we just unexpectedly stumbled into each other's lives. We have been dating for a year and are very happy together. Moral of the story: you never know what life has in store for you, and if I had given up when all odds were against me, I wouldn't be where I am today. This silly little game helped me realize that. Thank you.
