How to play

Each real second is one month. Your salary arrives every month, and inflation slowly eats cash that is not invested.
Invest your cash in a fund so it earns a monthly return. Better funds unlock as you grow, from savings accounts to rental property.
Turn on Auto for a fund and every paycheck goes straight into it. You can also ask for raises and hire advisors to boost returns.
Reach $1,000,000 in net worth to win. Your best time is the fewest months, so lower is better.

Do not leave cash idle. Even the plain savings account beats inflation, and it compounds.
Unlock the next fund when you can afford it. A slightly higher rate matters more and more as your balance grows.
Raises pay back quickly in the early game, while advisors matter more once you hold a lot.
Use the 5x and 20x speed buttons once your plan is running and you are only waiting.

Is this real financial advice?: No. It is a simplified game that shows how compounding works, with made-up rates, and it is not advice for real money.
Does the game keep running when I close it?: No. It saves where you are, but time only passes while the page is open.
Is my best time saved?: Yes, in this browser. The fastest win, in months, is kept.
