Roblox simulator economy

Choose the economy's numbers with a pacing table before writing gameplay code, then implement them so the server owns every amount. Code targets Luau on Roblox's rolling platform APIs; the bundled scripts are pure Luau and were run with Lune 0.11.0, outside Studio.

When to use

• Picking or reviewing baseCost, costGrowth, rebirth requirement and multiplier, or offline cap and efficiency values for a simulator, tycoon, clicker, or idle game.
• Writing upgrade, buy-max, currency, rebirth, or offline-earnings code in Luau.
• Displaying large numbers, or values above about 1e15 that lose precision.
• Adding eggs, crates, or spins bought with Robux, or with currency that can be bought with Robux.

When not to use: DataStore reads, writes, session locking and retries → roblox-datastores. Remote protocol design and rate limiting in depth → roblox-networking. Shop and HUD layout → roblox-ui + game-ui-ux. A wave-defense economy → tower-defense. Engine-neutral save format questions → save-systems.
