How to Make a Roblox Pet Simulator Game with AI
Hatch, collect, trade, chase the one-in-a-million.
Pet games are simulators with a collection layer bolted on, and that layer is what makes them enormous. The hatch animation is the product — a two-second wind-up with a rarity reveal at the end is a slot machine that children will pull for hours, and getting its pacing right matters more than anything else in the build.
The other half is trading. A pet economy where players can swap turns your game into a social space with its own market, and it's the reason the biggest pet games retain for years. Ask for it explicitly, along with the safeguards that stop it being abused.
Earn currency, spend it on eggs, hatch pets of escalating rarity, use them to earn faster.
If you can say your loop in one line, you've already written most of your prompt — this is the single most important sentence you'll give the maker.
What the AI has to build for a pet game
These are the systems this genre lives on. Naming them in your prompt is what turns a flat first build into one you can actually play.
Egg and hatch system
Weighted rarity tables with an animated reveal. The animation is the dopamine, not the pet.
Pet inventory and equipping
A collection UI, equip limits, and stacking multipliers from equipped pets.
Rarity tiers
Common through secret, with odds displayed. Visible odds build trust and drive chasing.
Trading
Player-to-player swaps with a confirmation window on both sides to prevent scams.
Index / collection book
A checklist of every pet. Completionists are this genre's most valuable players.
Three prompts, three very different games
Same genre, increasing detail. The difference between the first and the third is the difference between a baseplate and something you'd publish.
A pet simulator with eggs
A pet game where you hatch eggs, collect rarities and trade with other players
A pet simulator where coins are earned by breaking objects, spent on eggs in themed zones. Six rarity tiers from common to secret with displayed odds and a hatch animation that builds tension before the reveal. Equipped pets stack coin multipliers, capped at four. A collection index tracking every pet, and a trade window with two-sided confirmation. New egg added on a weekly rotation.

An instant hatch
The wind-up is the whole experience. An egg that opens immediately removes the reason to open another.
Hidden odds
Displayed rarity percentages make chasing feel fair. Concealing them reads as a scam to this audience.
Trading without confirmation
One-sided trades create scammers, scammers create refund requests and a reputation problem.
Getting players into a pet game
Pet games are driven by hatch-luck content — creators opening hundreds of eggs for a secret pet. Weekly egg rotations give creators a reason to return to your game.
Publishing is the halfway point — Roblox's discovery algorithm surfaces games that already have engagement, which is hard to break into from zero. Browse pet creators on the marketplace or read the full pet marketing guide for what works in this genre specifically.
Making a Roblox pet game with AI
Can AI really make a Roblox pet game?
It can build a working first version — egg and hatch system, pet inventory and equipping, rarity tiers and a playable map — from a written description. What it won't do is decide what makes your pet game worth playing. Expect a strong starting point you keep shaping rather than a finished game.
What is the core loop of a Roblox pet game?
Earn currency, spend it on eggs, hatch pets of escalating rarity, use them to earn faster.
What should I include in the prompt?
Name the loop, say how progress works and mention the social hook. For this genre that means being specific about egg and hatch system and pet inventory and equipping. Compare the three example prompts on this page — the longest one produces a dramatically better first build than the short one.
How do I get players once the game is published?
Pet games are driven by hatch-luck content — creators opening hundreds of eggs for a secret pet. Weekly egg rotations give creators a reason to return to your game.
