Idle Capitalist Loop
Welcome - press Play to load Idle Capitalist Loop. Empire saves stay under ftol:idlecapitalistloop:storage.
The loop is simple to start and deep to optimize: click a business row to buy units, tap to collect when its cycle bar fills, then hire a manager so that row runs itself. Milestone bonuses land at 25, 50, 100, 200, 300 and 400 units owned, rewarding steady reinvestment.
Key features
- Three planets to expand into - Earth businesses from a lemonade stand up to oil companies, then the Moon and Mars.
- A buy-quantity control and per-row progress bars, with managers that auto-collect a business once hired.
- Two upgrade tracks - cash upgrades multiply a business, while angel upgrades are bought with angels.
- Angel-investor prestige resets progress for angels that boost all profits, 2% per angel before upgrade bonuses.
- Offline earnings accrue while you are away, up to 12 hours at 25% efficiency when you return.
- Click or tap to play; on desktop, Space pauses, keys 1/2/3 switch Earth/Moon/Mars, and b/u/a switch the upgrade tabs.
When to use it
Reach for it as a background idle game: buy a few businesses, hire managers to run them, then close the tab and let offline earnings build up to twelve hours before your next visit.
Saves and privacy
Your empire autosaves every 10 seconds to ftol:idlecapitalistloop:storage in your browser, so progress survives a refresh. Wipe the save any time through the in-game confirm or the Settings panel. After the one-time download when you press Play, the game fetches no CDN scripts, fonts, or analytics.

Idle Capitalist Loop is adapted from the open-source Cursor Arcade capitalist module by flancast90 (MIT); this build stubs the VS Code APIs it originally used and ships its LICENSE and CREDITS. It is a fan-made idle game, not the commercial AdVenture Capitalist title or its branding.
