The crypto-casino world runs on jargon, and operators count on you not knowing it. These are the terms that actually decide whether you keep your money — short, plain definitions, each linking to the deeper forensic write-up where one exists.

Core terms

Provably fair
A cryptographic system that lets you verify a bet wasn't rigged after the fact, using server and client seeds. Deep dive: provably fair explained. Verify a real bet yourself with our Provably Fair Verifier.
Wagering requirement
How many times you must bet a bonus (and sometimes the deposit) before you can withdraw. "200% bonus, 35x wagering" can mean churning tens of thousands to keep a small win. Detail: wagering requirements explained.
Max cashout cap
A ceiling on how much you can withdraw from bonus winnings, regardless of how much you actually won. The quietest way a generous-looking bonus voids a big win — every offer's cap is surfaced by the Bonus Decoder.
Reserve-the-right clause
A line in the Terms letting an operator demand identity documents at any time, even on a "no-KYC" site. It's the difference between our "No KYC" and "No KYC detected" labels — see KYC Classification.
KYC trigger
The specific event — a large withdrawal, a flagged pattern, a payment method — that fires an identity check on a Soft-KYC site. What sets it off: KYC triggers.
RTP (Return to Player)
The long-run percentage of wagers a game pays back. 96% RTP means a 4% house edge over time — a statistical average, not a promise for your session.
Rakeback
A percentage of the house edge returned to you as you play — one of the few genuinely player-friendly mechanics. How it works: rakeback explained.
Withdrawal trap
When an operator markets anonymity or speed, then blocks a real cash-out with a sudden KYC demand or invented review. A Burn Pile offence — see Red Flags & Delisting.
Holding Tank
WagerX's watch-list for operators showing warning signs but not yet disqualified. What it means: Holding Tank explained.
Curaçao license
The most common crypto-casino license — low barrier, light oversight. Better than nothing, far from a guarantee. Context: licensing explained.
VPN policy
Whether an operator allows VPN access and how it treats geo-restriction. Hidden VPN bans are a common excuse to void winnings — detail: VPN casino policy.
No-KYC casino
An operator that lets you play and withdraw without identity verification. We reserve the unqualified "No KYC" label for sites verified end-to-end: No-KYC casinos.
