EVOLVE YOUR OWN AI ROBOT! You are the (zoo)Keeper overseeing a population of evolving AI robots in a dynamic voxel landscape. These robotic animats walk, jump, eat, mate, fight, and adapt to their surroundings as they strive to survive and reproduce. In theory, the capacity for their intelligence is limitless, as their brains can evolve to any shape and complexity. Will you choose to passively observe their evolution, letting nature take its course? Or will you intervene, shaping their world and influencing their evolutionary path? Design your own animal robots, build custom terrains, manipulate the environment, interact with the animals, and watch as each generation learns, adapts, and competes in a simulated ecosystem that’s as unpredictable as nature itself. The fate of their evolution is in your hands. --------- Introducing a new god game and evolutionary simulation, where you evolve the brains of artificial animals to make them more intelligent, to better achieve survival and reproduction. The animals are real AI robots running directly on your computer. They are controlled by classic neural networks and other types of AI such as non-axiomatic reasoning system. They have a simple form of vision sense, touch sensation, and internal sensations, and they can move each individual body segment. They can eat, mate, and fight, all while learning and evolving in a sandbox voxel environment. Watch evolution passively, or enjoy various interactive features including: + Voxel World: place voxels and modify the environment with sand, stone, water, and more. + Impact Evolution using your Research Journal: modify mutation rates in your Research Journal -- higher rates means faster but more unstable evolution, lower rates means slower but more stable evolution. + Pick up animats: Pick up animats and move the animats around with left click. + Build your own Robot: Go to the Animat Creator from the main menu to create your own robot. You can save it and load it into a simulation to evolve its brain! ## Key features - Evolving AI robots - Dynamic voxel landscape - Robot design and creation - Environment manipulation - Interactive evolutionary control - Simulated ecosystem ## Frequently asked questions about ERAIASON ### What is ERAIASON? ERAIASON is a god game and evolutionary simulation where you oversee and influence the evolution of AI robots in a dynamic voxel landscape. You can design robots, build terrains, and observe their adaptation and survival. ### What are the core gameplay mechanics of ERAIASON? Players act as a zoo keeper, managing AI robots that walk, jump, eat, mate, and fight. You can passively observe their evolution or actively intervene by designing robots, building custom terrains, and manipulating the environment. ### Can I design my own robots in ERAIASON? Yes, ERAIASON features an Animat Creator where you can design your own robot. These custom robots can then be saved and loaded into a simulation to evolve their brains. ### How does ERAIASON handle evolution? The game simulates evolution through neural networks and other AI types. You can influence the evolutionary path by modifying mutation rates in your Research Journal, affecting the speed and stability of evolution. ### What platforms is ERAIASON available on? ERAIASON is supported on iPhone, iPad, and iPod devices, indicating it is a mobile application. ### What is the price of ERAIASON? ERAIASON is a paid application, with a listed price of $4.99. ### How often is ERAIASON updated? The latest version of ERAIASON is 1.0.31, and it was last updated on February 20, 2026, suggesting a relatively recent update cycle. ### Does ERAIASON have ads? No, ERAIASON does not contain advertisements, as indicated by the 'hasAds' flag being false. ## Version history (last 5 releases) ### v1.0.38 — 2026-08-10 + Add Guides on the main menu that explain the various simulation options and how they work (e.g., brain types, robot types, and environment types) + New simulation option: "Evolve activation functions", allowing evolution to change the activation functions of neurons + New neuroevolution option: "developmental encoding", an indirect encoding that creates neural networks using developmental instructions + Animats can now steal energy when they attack other animats + New neuroevolution option: "Dale NEAT", where neurons can be excitatory/inhibitory and network weights are all positive + New simulation option: "Morphic Fields", this is a population-wide evolutionary memory that is used to bias mutations + Robot performance optimizations, to make the game run faster/smoother (especially at higher simulation speed multipliers, and with larger robot populations) + Bug fixes ### v1.0.37 — 2026-07-22 Animats can now produce and hear vocalizations. They can control pitch and amplitude of the vocalization, and evolution changes fixed characteristics of the vocalization. ### v1.0.36 — 2026-07-18 + New Neuron Type Available: "Leaky integrate-and-fire neurons" are now an option for brain neurons, allowing a more realistic brain type + New CPG Type: "Gated motor gait prior" is now an option for central pattern generator (CPG), enabling strong global rhythmic movement + New Plant Type: Poison Plants are now in the simulation; when eaten they decrease the energy of animats + New Simulation Option: choose the number of food plants and poison plants in the simulation + New Simulation Option: choose between 2 neuroevolution methods, NEAT or Deep-HyperNEAT + Plants: Plants now reproduce and evolve + Evolution: MAP-Elites algorithm implemented to improve the speed and efficiency of evolutionary search + UI: Add a "save successful/failed" popup for feedback when saving robots and simulations + UI: New cleaner Research Journal UI + Localization: make more text translate when language changes (some text was previously English-only) + Optimization: Convert some of the Unity MonoBehaviour code to Entity Component System (ECS) for better performance ### v1.0.35 — 2026-06-12 + Fix crash when opening journal ### v1.0.34 — 2026-06-11 + New Feature: Plants now grow in the simulation, instead of food cubes + New Simulation Option: Evolve robot bodies + New Brain Type: Reservoir computing + New Rendering Option: Raymarched voxel world + Bug fixes ## Apps similar to ERAIASON | App | Rating | Price | Category | | --- | --- | --- | --- | | [Shrimp Game Classic](https://appshunter.io/ios/app/shrimp-game-classic/id6740584079) | 3.3 (3) | Free | Games | | [Wacky Genes](https://appshunter.io/ios/app/wacky-genes/id1641711708) | 3.9 (37) | Free | Games | | [Slime Evolution 2](https://appshunter.io/ios/app/slime-evolution-2/id6630381726) | 4.4 (14) | Free | Games | | [Whisker Grove](https://appshunter.io/ios/app/whisker-grove/id6476961480) | 3.9 (73) | Free | Games | | [Command of Europe](https://appshunter.io/ios/app/command-of-europe/id6760222986) | 4.5 (21) | Free | Games | | [Evolution - Learning Creatures](https://appshunter.io/ios/app/evolution-learning-creatures/id1227314223) | 4.4 (549) | $1.99 | Games | --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
