Question 1

How are drop chances on Gamma calculated?

Accepted Answer

Each item is assigned a contiguous ticket range inside the 100,000-bucket spin space. The percentage shown on screen is that range divided by 100,000, rounded for display. The widths sum to exactly 100,000, so the on-screen odds always sum to 100%. There are no hidden "near miss" mechanics, no per-account adjustment, and no dynamic re-weighting between spins — the same configuration applies to every player and every opening.

Question 2

How does a single spin actually work?

Accepted Answer

When you press Open, the server draws one integer ticket from a uniform 0–99,999 range using HMAC-SHA256 over the active server seed, your client seed, and the spin nonce. The case configuration tells the server which item that ticket belongs to. A second HMAC draw resolves the wear variant inside that item's sub-ranges. The animation is purely cosmetic — by the time the reel starts moving, the result is already determined and committed.

Question 3

Can I verify a Gamma opening myself?

Accepted Answer

Yes. After opening, note the spin nonce shown in your case history. Rotate your seeds in Settings to reveal the server seed for that spin, then open the Cases verifier on the Provably Fair page and supply the server seed, your client seed at the time, the nonce, and the case ID. The verifier replays the ticket draw against the published item ranges; the resulting item and wear must match what you saw on screen.

Question 4

How are wear variants resolved?

Accepted Answer

Each item that ships with multiple wears (Factory New, Minimal Wear, Field-Tested, Well-Worn, Battle-Scarred) has its own sub-distribution — also published in the case configuration. Once the spin lands on an item, a second uniform draw selects a wear bucket using the same HMAC-based RNG and the same seeds. That is why two players opening the same item from the same case can still receive different wears, and why the verifier always asks for both the item ticket and the wear ticket.

Question 5

What does the price next to the case represent?

Accepted Answer

It is the cost in coins to open the case once. That cost funds the prize pool and represents the expected value of the drop table within the published house edge. Items pulled from the case are credited to your inventory at their listed sell-back value; depending on the spin you can come out well above or well below the case price. Across many openings, results converge toward the published expected value.

Question 6

Are there limits on how many times I can open the same case?

Accepted Answer

There is no hard cap on paid openings — you can open the same case as long as your balance covers the cost. Free or promotional versions of a case may carry per-day or per-promo limits to keep the bonus economy fair; those limits are shown on the open button and inside the offer. Personal play limits set in Settings (deposit, wager, or session limits) will further restrict how much you can spend in a window.

Question 7

Why did I get a low-tier item even though the rare items have a real percentage?

Accepted Answer

Because rare items are, by definition, rare. Even a 1% drop means roughly one in a hundred openings on average, and the actual gap between hits can be far longer or far shorter — that is what randomness looks like in small samples. The percentages are honest and verifiable; what they do not promise is when the rare item will land. Use the verifier to confirm any individual opening was generated correctly.

Question 8

Can I use this case in a Case Battle?

Accepted Answer

If the case is eligible for battles it will appear in the Case Battle case picker. Inside a battle every seat opens the same case sequence at the same time using a shared server seed and per-seat entropy (your player ID), so opponents cannot collude on outcomes. The fairness verifier supports both modes — you can verify a solo spin and a battle spin with the same tool.

Question 9

What happens to items I open from this case?

Accepted Answer

They go straight to your inventory at their listed value. From there you can keep them, sell them back to the platform to credit your balance instantly, or use them as entry stakes in features that accept items. Withdrawal-style options, where available in your region, are explained inside the inventory and cashier; always read the active terms before initiating one.

Question 10

How do I know the drop table has not changed since I last opened?

Accepted Answer

Case configurations are versioned. The drop table you see when you open the case is the one the server uses for that spin, and the verifier accepts the case ID and version that were active at spin time. If a case is updated, older spins remain verifiable against the configuration that was live when they were opened, so you can audit history even after a refresh of the lineup.
