How to Make a Roblox Simulator Game with AI
Numbers that go up, pets that hatch, rebirths that reset the curve.
Simulators are the most forgiving genre to build and the least forgiving to balance. The structure is simple — click or collect, sell, upgrade, repeat — which is exactly why an AI can scaffold a working one quickly. What separates the ones with 40 concurrent players from the ones with 40,000 is entirely in the numbers: how fast the first upgrade arrives, how long the third zone takes, whether a rebirth feels like a reward or a punishment.
That makes simulators an ideal first project. You get something playable almost immediately, and then the interesting work is tuning, which you can do by prompting rather than rewriting systems. Describe the pacing you want — "the first upgrade should be affordable within 30 seconds, the second within three minutes" — and iterate from there.
Collect a resource, spend it on something that collects faster, rebirth when the curve flattens.
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 simulator 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.
Currency and collection
A resource that accrues while the player is active, with a per-second rate that upgrades multiply.
Upgrade tree
Tiered purchases that raise the collection rate, each priced so the next one is always visible but not yet affordable.
Rebirth / prestige
A reset that trades current progress for a permanent multiplier. Without it, players hit a ceiling and leave.
Data store persistence
Progress has to survive a rejoin. Nothing kills a simulator faster than losing an hour of grinding.
Pet or companion system
Optional but near-universal — hatching gives players a reason to spend and a reason to come back tomorrow.
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 simulator where you mine ore and upgrade your pickaxe
A mining simulator with five zones, each gated behind a pickaxe tier, plus pets that boost mining speed
A mining simulator where you dig for ore, sell it at a surface shop, and buy pickaxe tiers that unlock five progressively harder zones. Pets hatch from eggs bought with ore and give stacking speed multipliers. Rebirth at 1M ore for a permanent 2x, and keep a rebirth leaderboard in the lobby.
Try this promptWhat kills most Roblox simulator games
The first upgrade is too far away
If a new player can't afford anything in the first minute, they leave. Front-load the curve hard — the first three upgrades should feel almost free.
No reason to return tomorrow
Daily rewards, timed eggs or rotating zones are what turn a one-session game into a habit. Build the return hook in from the start.
Rebirth that feels like a loss
If prestige resets everything and gives back too little, players won't do it twice. The first rebirth should visibly accelerate the next run.
Getting players into a simulator game
Simulator audiences skew young and follow specific creators as walkthrough authorities. A code drop paired with a mid-tier simulator YouTuber typically spikes concurrents within hours.
Publishing is the halfway point — Roblox's discovery algorithm surfaces games that already have engagement, which is hard to break into from zero. Browse simulator creators on the marketplace or read the full simulator marketing guide for what works in this genre specifically.
Making a Roblox simulator game with AI
Can AI really make a Roblox simulator game?
It can build a working first version — currency and collection, upgrade tree, rebirth / prestige and a playable map — from a written description. What it won't do is decide what makes your simulator game worth playing. Expect a strong starting point you keep shaping rather than a finished game.
What is the core loop of a Roblox simulator game?
Collect a resource, spend it on something that collects faster, rebirth when the curve flattens.
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 currency and collection and upgrade tree. 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?
Simulator audiences skew young and follow specific creators as walkthrough authorities. A code drop paired with a mid-tier simulator YouTuber typically spikes concurrents within hours.
