Invest before the ending is obvious
Most market simulators give you the company name and the era right away. Blindfolio hides both, so each decision starts with the evidence on the screen: price, risk, valuation, news and your own discipline.
What you play
Each round covers 10, 15 or 20 years between 1962 and 2026. Time moves month by month: assets appear, news lands, prices move, and the era is named only after the result.
Why it feels different
The catalog includes famous winners, forgotten laggards, bonds, commodities, crypto, cash, and selected bankrupt or delisted companies. It is not a museum where only survivors remain.
The goal
Build a portfolio that beats the S&P 500 over the same hidden period. Sometimes that takes conviction, sometimes patience, and sometimes the honest answer is that the index did better.
