Questions

Why is the Gamma Case payout below 100%?

The case and key cost $5.38, and almost everything that drops is a cheap skin: 79.92% for the lowest tier, 0.26% for a knife or gloves. Multiply the odds by market prices and you get 61% — that much of every 100 comes back on average.

Where do the prices come from?

The best market offers at the time of the calculation: Skinport, CSFloat, Market.CSGO, DMarket, Waxpeer and White.Market. That is what a drop actually sells for, not a display price.

What does “openings until zero” mean?

The way cases are really opened: sell the drop, open again while you can afford a case. For Gamma Case that is 23 openings on average — then the balance is below the opening price. Everyone gets there: a payout below 100% works like gravity.

What if I get lucky?

Over 18 openings the chance to pull ★ Karambit | Gamma Doppler is 0.1%, the chance to double the budget is 4.0%. Both numbers are honest, and both are small.
