## What is Evolution?

Use joints, bones and muscles to build creatures that are only limited by your imagination. Watch how the combination of neural networks and an evolutionary algorithm can enable your creatures to learn and improve at their given tasks all on their own.

The tasks include running, jumping, climbing and flying. Can you design the ultimate creature that is good at all of the tasks?

The latest update allows you to easily share your simulation saves and creature designs with your friends.

Note that this is more of a simulation than a game. There are no real objectives. But there is a lot to learn if you are interested in the basics of machine learning and neural networks. You can even look at the source code if you want.

There is also a Mac & PC version available for download and a browser version for you to try out on the main project website (keiwando.com/evolution).

### 5/5 — My slinky bounced out of the universe

*2026-04-13, version 4.0.5*

It was on jumping and at gen. 44 it bounced so high that I couldn’t even explain what just happened lol

### 4/5 — Amazing app, one small problem currently.

*2026-02-14*

If i could rate half stars, this would get a solid 4.5 stars.

This (game? simulator?) is great because you can make a critter and see it fail over and over, then learn how to do things. (P.S if your creature is shimmying on the ground instead of keeping it's feet below itself, select the joints you don't want touching the ground and give them a large negative point bonus!)

Now, for the problem I have currently: There's a 'tip' screen which keeps popping up saying "Add joints and connect them with bones." Because of this, even zooming in makes this pop up if a joint is not placed on the grid.

9.5/10

### 4/5 — Why can’t I delete the starting creatures?

*2025-12-31*

The whole games great except for one thing! Whenever I delete all the creatures you get when you first download the app (or the frogged symulation you also get), the next time I open the app, they just re-appear! I have no idea why this would happen other then it being intentional coded into the game! So please, just change this!

### 4/5 — This game is great and I have a suggestion.

*2025-11-21, version 4.0.5*

My suggestion for this game is adding a life simulation. Players could decide if their creature is predator or prey, and add them to some kind of terrain. Maybe you could also add water creatures as well.

### 5/5 — Carykh sim? (5 stars so you can see this)

*2025-09-26, version 4.0.4*

Isnt this just carykh’s sim but an unoffical mobile port

### 5/5 — Great App

*2025-08-30, version 4.0.3*

Awesome app. Love it

### 4/5 — Where are feathers

*2025-08-22, version 4.0.2*

One of the pictures shows a creature with feathers but in game I don’t see feathers

### 5/5 — ?

*2025-08-14*

It’s great but how do I access the wing items or feathers, did you remove them
?

**Developer response:** Select a bone with the “Select” tool and then you get the option to turn on wings for that bone.

### 3/5 — This game needs an obstacle creator or some kind of an obstacle mode

*2025-08-11, version 4.0*

This game is awesome, but I would love to create an obstacle course for my creation to go through. Or maybe just an obstacle mode

### 5/5 — Good

*2025-06-22, version 3.1.0*

I like evolution

## Version history (last 5 releases)

### 4.0.5 — 2025-10-06

This update addresses the recently discovered security vulnerability in the Unity game engine (CVE-2025-59489).

### 4.0.4 — 2025-09-06

- Stability Improvements

Changes in version 4.0:
- Save recordings of your favourite simulation results in the new gallery.
- Choose from a list of skins such as googly eyes, noses, hands, feet and more and attach them to your creature's bones for a more personalized look. Skins are purely cosmetic and do not affect the simulation.
- Tap a selection of body components with the move tool to show scale and rotation handles for precise adjustments. This is especially useful for fine-tuning the orientation and size of the new skins.
- Improved the performance of save file loading and saving and reduced the memory usage during the simulation.
- The camera now follows the creatures vertically as well, so your flying creatures won't fly out of view.
- Added a background grid to the simulation screen to help see the movement of flying creatures once the ground is no longer visible.
