About This Demo

Welcome to Reptilarium — your personal reptile sanctuary built from humid leaves, sun-warmed stones, and quiet glass walls. Discover, care for, and grow hundreds of unique reptile species across beautifully crafted terrariums.

Bring Your Reptiles to Your Desktop

With a single click, your reptiles leave the terrarium and roam freely across your real desktop — calm, transparent companions wandering over your windows while you work, study, or browse. They never get in the way: clicks pass right through them, and a tap of ESC sends them home. Your living collection, alive on your screen.

Collect Hundreds of Unique Reptile Species

Build the ultimate reptile library. Each species is assigned one of seven rarity tiers — from Common to Ancient. Unlock stunning visual variants: Normal, Painted, Golden, and Rainbow. Complete your collection and discover species you've never seen before, from tiny geckos to majestic chameleons.

Watch Eggs Hatch and Babies Grow

Witness the wonder of life as eggs crack open and tiny hatchlings emerge. Watch them grow into magnificent adults in real time. Release them for instant rewards, or keep them in your terrarium for steady passive income. Every decision shapes your strategy.

Earn While You're Away

Your terrarium keeps growing in the background while you work, study, or browse the web. The automatic feeding system keeps your reptiles happy and fed; when you return, gathered rewards are waiting. No pressure, no timers — just progress at your own pace.

Design Your Dream Terrariums

Choose from background themes, lighting, decorations, and day-night settings. Customize multiple terrariums exactly the way you want. Keep them lush and tropical, or stark and desert-bright — this is your sanctuary, your rules.

Compete on Global Leaderboards
