About Sixty-40
A game about the one thing every investor has too much of: hindsight. Here is how it works.
The rules
You start with $10,000 and ten slots of $1,000. The wheel lands on a year between 1990 and 2020 and an asset class — US stocks, world stocks, commodities, crypto, real estate, country indexes, bonds and cash, collectibles, or pure hype. You get five positions to choose from at the price they traded for then, and ten seconds to decide. Hesitate and that slot stays in cash. After ten picks we simulate everything to today and show you one number: what your $10,000 became, and whether it beat the S&P 500 over the same years.
Daily and free play
The Daily gives everyone in the world the same ten spins and the same options, once a day. Share the emoji row, not the answers: 🟩 beat the index, 🟨 gained but trailed it, 🟥 lost money, 💀 went to zero, ⬜ too slow. Free play spins a fresh wheel every time and remembers what you have already seen so you keep meeting new positions. A duel link replays your exact spins for a friend.
Scoring and titles
Your result is ranked against thousands of simulated ways the same game could have gone. That gives you a percentile and a title, from Rekt through Bag holder, Index hugger, Trader, Sharp and Hedge fund to Oracle (top 1%).
The data
The catalogue has 258 positions, including companies, coins and funds that no longer exist — because a game about hindsight without Enron, Lehman, Terra Luna and Pan Am would be cheating. Prices are approximate start-of-year values, adjusted for splits and excluding dividends, drawn from public sources. Collectibles, houses and commodities use widely reported reference prices. Treat every number as illustrative; if you want precision, use a broker's data, not a game. Nothing here is advice.
Who makes it
Sixty-40 is made by a very small team in the Netherlands and paid for by advertising, so it stays free and needs no account.
