Gold Digger is a game about reading markets — so its price is set bythe market. It floats, it's public, and you can check every number yourself. That's the whole point.

Lifetime — the Vault Pass
$16.50

= yesterday's VIX close (16.50, as of the last market close). The market's fear gauge. Volatility, priced in.

CBOE Volatility Index (VIX) ↗VIX daily close — St. Louis Fed (FRED) ↗
Annual
$5.79/yr

= the price of a Big Mac in the US. The most famous index in economics. The experts charge $50,000.

How it's calculated

  • • Lifetime reads the VIX's most recent daily close from CBOE's public data and charges exactly that (floored at $9 so it's never silly). When markets panic, the Pass costs a little more. Poetic.
  • • Annual tracks The Economist's Big Mac Index for the US (currently $5.79), refreshed as they publish.
  • • Checkout is Gumroad pay-what-you-want with the live figure as the suggested price — so the number you see here is the number you pay.

Free forever: both game modes and the ranked leaderboard. The Pass unlocks depth — calibration-by-regime, the full library, and Gwen's Dossier.

The price floats with the market. Honest, and slightly unhinged — like the game.
