Simulators are some of the biggest games on Roblox. You click, you collect, you sell, you upgrade, and then you do it all again a little faster. It sounds simple, and that's the point. But a lot of simulators get played once and forgotten. The ones that last give players a reason to come back tomorrow.
This guide has 15 simulator ideas, then the five design tricks that keep players returning. Use them together and your simulator will feel a lot more polished than "click the button, number goes up."
The simulator loop in one sentence
Almost every simulator follows the same loop: do an action to gather something, sell it for coins, spend coins on upgrades that let you gather faster, and unlock a new area. The fun comes from what you gather, where you gather it, and how the upgrades change the way you play.
So when you plan a simulator, answer four questions first:
- What do players gather? (snow, fish, bugs, music notes)
- What tool do they use? (a shovel, a net, a vacuum, a magic wand)
- Where do they sell it? (a shop, a portal, a hungry monster)
- What's the first new area they unlock?
If you can answer all four, you have a simulator.
15 simulator ideas
- Snow Globe Simulator. Shovel snow inside a giant snow globe and sell snowballs. New zones are other snow globes on the same shelf.
- Underwater Fishing Simulator. Catch fish with better and better rods, then sell them at a coral market. Rare fish show up only at night. (Try this idea)
- Bug Collector Simulator. Catch bugs with a net in your backyard. Each bug can become a pet that helps you catch more.
- Volcano Mining Simulator. Mine glowing rocks on a volcano. The deeper zones are hotter, so you need heat-proof boots to enter.
- Bakery Simulator. Tap ovens to bake bread, sell it to NPCs, and unlock fancier recipes like rainbow cake.
- Cloud Kingdom Simulator. Collect fluffy clouds with a vacuum and sell them to make rain. New sky islands float higher and higher.
- Dinosaur Fossil Simulator. Dig up bones and rebuild dinosaur skeletons for a museum. A finished skeleton gives you a permanent bonus.
- Music Note Simulator. Bounce on drums and pianos to collect notes. Different instruments give different notes.
- Wizard Spell Simulator. Cast spells at magic crystals to gather mana. New spells make gathering faster and look cooler.
- Pizza Delivery Simulator. Deliver pizzas across town for tips. Upgrade from a skateboard to a jetpack.
- Toy Box Simulator. You're a tiny toy collecting buttons in a giant kid's bedroom. Each new zone is a different shelf or drawer.
- Moon Base Simulator. Collect moon dust with low gravity, so jumping is part of the gathering.
- Garden Simulator. Plant seeds, water them, and sell giant vegetables. Weather changes which plants grow fastest.
- Robot Builder Simulator. Gather scrap metal and build robot helpers that gather for you.
- Treasure Diver Simulator. Dive for sunken treasure. Better oxygen tanks let you go deeper.

Five tricks that bring players back
1. Rebirths
A rebirth lets players reset their coins and upgrades in exchange for a permanent boost, like 1.5x coins forever. It turns the end of your game into a new beginning. Players who were about to quit suddenly have a fresh goal. Show the next rebirth's reward on screen so players can see what they're working toward.
2. Pets that do something
Pets are huge in simulators because they're collectible and they help. A pet that follows you and adds +10% gathering is much more exciting than a pet that just sits there. Hatch pets from eggs bought with coins, and give each zone its own egg so exploring pays off. Keep the odds clear and kid-friendly, and let players earn every pet with in-game coins.
3. Zones with a gate
Each new zone should feel like a reward: new colors, new music, a new thing to gather. Put a gate in front of each zone that costs coins to open. When players see the next zone through the gate, they have a reason to keep playing.
4. Daily goals and gifts
Give players a small reward for logging in each day, and two or three daily quests like "collect 500 snow" or "hatch 3 eggs". Daily goals are the single easiest way to get players to return tomorrow. Make the rewards stack, so day 7 is bigger than day 1.
5. Things to show off
Leaderboards, rare pets, glowing tools, and titles like "Snow King" give players something to brag about. Put a leaderboard in the lobby so everyone sees the top players when they join.
Fair ways to monetize a simulator
Players are happy to support games that treat them fairly. Good simulator Game Passes include 2x Coins, Auto-Collect, Extra Pet Slots, and Faster Hatching. These save time but don't stop free players from having fun. Avoid paywalls that block the main game, and always make sure everything important can be earned by playing. If you're a kid, ask a parent before you set up anything that sells items.
How to build your first simulator
A starter simulator needs only three things: a leaderboard with two stats (what you gather and Coins), a Tool that adds to the first stat when you click, and a sell pad that turns it into Coins. Every simulator idea on this site has a Build it in Studio plan with those three scripts ready to copy, and the stat names match the idea (Fish for a fishing simulator, Ore for mining, and so on).
