Explore a serene artificial-life playground where you cultivate tiny Neeblies and design their habitats. With every click, watch these digital creatures evolve in parallel worlds, all while deciding the fate of their families and traits.

About this game

The Neeblarium is a calm, living simulation about cultivating tiny digital creatures called Neeblies and deciding what’s worth preserving. You don’t control Neeblies directly. You shape conditions, observe what emerges, and intervene only when it matters.

Over time, families form. Lineages diverge. Rare traits appear. Some discoveries are fleeting. Others are worth saving.

Use your Lab to capture traits you’ve discovered and reintroduce them as new founders. Run multiple biomes as experiments, each telling its own quiet evolutionary story.

The world keeps moving whether you act or not.

An artificial life sim about attention, care, and making something last.

Your role in The Neeblarium:

  • Establish conditions for life within a running ecosystem

  • Introduce eggs and observe Neeblies grow, adapt, and reproduce on their own

  • Watch families form and lineages diverge across generations

  • Notice mutations, rare traits, and subtle behavioral differences as they emerge naturally

  • Use a Lab to preserve discovered traits and reintroduce them as new founders

  • Run multiple biomes in parallel, each evolving independently over time

  • Decide when to intervene, curate, or simply let things run

Your choices shape long-term outcomes, but the system never demands constant micromanagement.

You can be hands-on, or almost completely hands-off.

The simulation doesn’t demand constant input — but it does reward attention.

    v0.8.0.1790: Your first bloom, sooner!

    Your first bloom, sooner Keepers, a small update with a big change to your first half hour. Some of you told us the early game felt like a long wait, and that the Lab seemed out of reach when every Neeblie was Common. You were right on both counts, and we found why: a mating cooldown meant for after a birth was also being applied to Neeblies who had never bred at all. No matter how ready a young pair looked, nothing could happen for roughly twenty minutes. That is fixed. What's changed Founders' Bloom. The first eggs from your Foundational Strain now grow up quickly and pair off within a few minutes of hatching, so your colony's first live birth is something you'll see, not something you'll wait for. The Lab opens with new life. The Lab now unlocks the moment your colony has its first live birth. You no longer need an Uncommon to get inside. Genome Capture comes next. Discover an Uncommon rarity and the Lab's Genome Capture unlocks, letting you preserve thriving Neeblies as blueprints and encode them into new eggs. A little guidance along the way. Hover the locked Lab tool to see how close your first pair is to blooming. If you've already been running a habitat and had a live birth before this update, the Lab will be waiting for you when you load in. A small invitation Start a fresh bed, place a couple of Foundational eggs, and stay a while. Watch them grow. The first new life in a colony is one of the quiet moments this game is built around, and it should never be the reason someone walks away. Thank you for your patience and your honesty. Keep telling us where the waiting feels long.

    Update 0.8.0! A More Living World

    The Neeblarium Major Update is here Keepers, this is a big one. I’ve spent the last several months touching a lot of the game: Neeblie behavior, toys, research, early-game pacing, the Lab Bot, save/profile handling, UI scaling, and a pile of smaller fixes that should make the habitat feel smoother and more alive. What changedNeeblies are more playful, curious, and believable around toys.Toys have better discovery, dragging, tidying, carrying, and save/load behavior. Research and unlocks should feel more earned, especially around enrichment, superfoods, and the Lab Bot. The Lab Bot has new upgrade paths like Genetic Flagging and Discovery Assist.Early guidance is calmer and better paced, with fewer popup piles.Births, blooms, discoveries, and colony moments are easier to notice.Saves, lineage data, bed removal, threaded simulation, and profile handling have all been hardened.UI scaling, start screen layout, icons, and fresh profile tools got a cleanup pass. A quick note before you jump in Because this update touches so much old colony/profile/save logic, there are probably bugs. Some existing profiles may behave strangely too. If something feels off, starting with a fresh profile may be the cleanest path. That said, I’m really excited about this update. The Neeblarium is getting closer to the game I want it to be: strange, cozy, a little surprising, and full of tiny stories happening when you’re not looking. Please send feedback, bug reports, weird moments, confusing moments, and anything that feels good or bad. Every bit of it helps make the game better. Thanks for taking care of these odd little lives.

    New build! 04.20

    It's been a while, but excited to share a new build. The Neeblarium feels a little more alive. Neeblies now have more small moments, sounds, memories, growth beats, and colony milestones to notice as you care for them. Toys got a big comfort pass: they can be placed, picked up, returned to the tray, saved properly, and even tidied back home by helpful adult Neeblies when they wander too far. The inspection lens has been polished into a clearer, cozier study tool, with better placement over your Neeblie and a more natural feel. This update also adds gentler onboarding hints, improved language support, cleaner options, safer saves, better backup recovery, and a handful of UI comfort fixes for readability and accessibility.

    Under the Surface

    It’s been a little quiet on the surface, so I wanted to share what’s been taking shape behind the glass.At a high level, I’ve been reworking one of the most fundamental parts of the simulation:Neeblies are becoming more self-directed.Less “follow a script.” More “decide, learn, adapt.” This is groundwork, not a playable update yet.You won’t see these changes in your current build—but they’re what the next major updates are being built on.🌿 A Shift in How Neeblies ThinkUntil now, Neeblies mostly responded to the world in fairly predictable ways. What’s changing is where decisions come from.Going forward:Each Neeblie decides when something is worth thinking aboutNeeds aren’t simple on/off states, but competing pressuresPast experiences matterPersonal tendencies matterThe world presents situations. Neeblies decide how (or if) to respond.This opens the door to behavior that feels observed, not authored.🧠 What This Makes PossibleThis foundation allows Neeblies to:React differently to the same situationLearn from outcomes over timeDevelop preferences instead of fixed routinesPass useful behaviors to offspringForm local patterns that persist across generationsYou won’t see explicit rules like:“Go eat now.” “Return home.”Instead, behavior emerges from:“Something feels off → I remember what worked → I try.”That’s where the magic starts to happen.🔧 What’s Actively Being BuiltThere are two threads of work moving together:1. The Long-Term ModelThis defines what “fully alive” Neeblies should look like:Motivation driven by layered pressuresShort-term awareness, long-term memoryLearning through success and failureYoung Neeblies imitating successful adultsA small set of simple actions combining into complex behaviorThis work sets the destination, even if not everything arrives at once.2. The Practical FoundationThis is the version that notice­ably changes the game:Neeblies choose when to evaluate their situationPerception, memory, learning, and imitation are now distinct systemsThe...

Your saves are safer, progression reads more clearly, and the world behaves more predictably as it grows.As always, feedback from keepers continues to shape where things go next.
