Make the decision before the famous name is revealed
Blindfolio turns investing into a short historical test: allocate capital, read the clues, live through drawdowns, and only later learn whether you bought a future legend or walked into a trap.
It tests how you think
Because the names are hidden, you cannot lean on fame. Diversification, position size, macro news and risk control matter more than brand recognition.
Fast, but still historical
One round compresses years of decisions into minutes while keeping the real order of market events and the S&P 500 comparison.
Built to replay
Random starts and temporary codenames make each round feel fresh, even though the data comes from real markets.
