Questions
Why is the Prisma Case payout below 100%?
The case and key cost $3.68, 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 58% — 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 Prisma Case that is 37 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 27 openings the chance to pull ★ Talon Knife | Doppler is 0.1%, the chance to double the budget is 4.3%. Both numbers are honest, and both are small.
