A blind investing game built from real market history
Blindfolio gives you a hidden 10, 15 or 20 year market period. Company names and the exact era stay hidden while you build a portfolio and try to beat the S&P 500.
Hidden names
Companies appear as temporary codenames during play, so famous brands do not answer the question for you.
Real sequence
Prices, macro conditions and era news follow historical order where possible, including crashes and recoveries.
Index comparison
The final screen compares your portfolio with the S&P 500 for the same hidden period.
How a round works
Choose a setup
Start a random round or choose a starting decade. You can play 10, 15 or 20 years.
Allocate capital
You receive starting cash and recurring income, then decide what to buy, sell or leave untouched.
React to history
New instruments, news, inflation, rates and personal events arrive as the months pass.
Reveal the era
At the end, the years and real company names are revealed, along with best and worst picks.
FAQ
Is Blindfolio a broker?
No. Blindfolio is an educational browser game and does not execute real trades.
Why are company names hidden?
Hidden names keep the decision focused on the facts in front of you, not on the famous outcome you may already know.
Does the game include failed companies?
Yes. Selected bankrupt and delisted companies are included so the game is not only about survivors.
