Roblox game ideas: thirty concepts, and how to turn one into a game

Tycoon and simulator

Loops that climb, with a twist.

• A bakery tycoon where every oven bought wakes up a pickier customer.
• A space-station tycoon where oxygen is the currency and every brick burns some.
• An island tycoon that sinks into the sea if you stop building.
• A cloud-collecting simulator where your bag grows heavier than you.
• A gardener simulator where plants grow while you are offline, but so do the weeds.
• An archaeologist simulator where each zone dug reveals the next zone's map.

Obby and parkour

Courses that change the rules of jumping.

• An obby where each checkpoint takes an ability away: jumping, then running, then sight.
• A city parkour where rooftops collapse behind the first player through.
• A two-player obby where one sees the platforms and the other sees the traps.
• A tower where each floor is drawn by the player who finished it first.
• A reversed obby: you start at the top and gravity flips at every stage.

Horror and survival

A readable threat, a simple rule, a reason to shiver.

• An abandoned hospital where the creature only moves when nobody is looking.
• A survival game on a ship that sinks one deck every five minutes.
• A house where the rooms swap places every time a door closes.
• A forest survival where the campfire is the only safe spot, and wood the only fuel.
• A round where the monster is a player who does not yet know their role.
• An eight-player bunker where light costs shared electricity.

Roleplay and social

Places to live in, roles to take.

• A mountain village where the weather changes which jobs are available.
• A school where students vote every day on the next lesson.
• A café where recipes are invented by customers and kept by the server.
• A ten-storey building where each flat has an owner and a rule.
• A fishing harbour where the price of fish depends on what others caught.
• A hotel that players run in turns, review by review.

Competitive and rounds

Rules that fit in one sentence and three-minute rounds.

• A 1v1 arena where the map loses a tile at every elimination.
• A murder mystery where the killer returns as a ghost that possesses props.
• A hide-and-seek where hiders become furniture, but only one piece can move.
• A forty-player elimination show where each minigame's loser picks the next one.
• A race of cars in spare parts, assembled during the countdown.
• A capture-the-flag where the flag is a volunteer player.
• A pumpkin battle where every missed throw becomes an obstacle.

From sentence to brief

An idea becomes a game when it answers four questions, in this order: what is the loop (what the player does every thirty seconds), which systems run it, how you progress from one session to the next, and what sells. That is exactly the form Builblox reads best. Take the sinking-ship idea:

Build a survival game on a sinking ocean liner.

Core loop: 2 to 10 players grab supplies and tools from the lower decks before the water reaches them, and climb back up to build a raft on the top deck.

Systems:
- A 5-deck liner; the water rises one deck every 5 minutes, and a flooded deck becomes unreachable
- Crates to open containing planks, ropes, food and fuel cans, carried one item at a time
- A workbench on the top deck: 8 planks and 4 ropes make a raft for 2 players, fuel cans make it faster
- An oxygen bar underwater, and a hunger bar that drains food
- Rats that steal food left on the floor
- When the last deck floods, players on a raft win, the others are swept away

Progression: rescues and items recovered saved with DataStore, a leaderboard of best rescuers.

Monetisation: gamepass for a vest that doubles oxygen, developer product for a starter crate.

Checking that an idea has an audience

Before building, look at what works right now: TrackBlox tracks Roblox games, their players and their rises all day, so you can compare your idea with what the platform actually plays. The Pro plan adds "Game Ideas" and "Analysis", which score an idea before you build it. And when you hesitate between two ideas, build the smaller one: it will be playable today, and its players will tell you what comes next.
