Crypto Casino Glossary
In-depth guide for crypto casino players.
Speaking the language of crypto casinos in one sitting
Crypto casinos blend the vocabulary of online gambling with the vocabulary of cryptocurrency, and the combination produces an acronym storm that can be impenetrable for new players. RTP, GGR, NGR, WR, KYC, AML, RG, ADR, EGM, CGA, LOK, MGA, MiCA, FATF, FIFO, LIFO, BTC, ETH, USDT, USDC, TRC-20, ERC-20, BEP-20, SOL, TON, XMR — and that is before getting to the operator-specific terms. This glossary covers the vocabulary you will see across casino terms of service, bonus contracts, regulator filings, affiliate marketing copy and player community chat. Each entry is written to stand alone so the page can be searched by Ctrl-F or used as a reference rather than read linearly. The terms have been gathered from the actual language used at Stake, BC.Game, Roobet, Cloudbet, Shuffle, Mega Dice, Duel and the major game studios as of May 2026.
What this glossary covers
Two and a half decades of online gambling, fifteen years of cryptocurrency, and the regulatory waves of 2024-2026 have produced a language that crosses several professional disciplines. This glossary covers ten domains: payments and crypto, game mechanics, bonus terminology, regulatory and licensing, KYC and AML, responsible gambling, operator product features, technical fairness, esports and sportsbook adjacent vocabulary, and dispute resolution. Around 90 definitions in total. The most-used twenty are repeated near the top for skim-readability.
How to use the glossary
Each entry is one or two sentences plus a typical context. Cross-references between entries link related concepts. Where a term has multiple meanings the glossary disambiguates by domain.

Common mistakes and red flags
- Confusing GGR with NGR. GGR is wagers minus winnings; NGR subtracts bonus costs, tax and chargebacks. Affiliate RevShare contracts almost always pay against NGR, not GGR.
- Equating Anjouan with Curaçao. Both are offshore but Curaçao under the LOK reform has materially stronger compliance and consumer-protection requirements.
- Treating rakeback as cashback. Rakeback returns a share of total wagers; cashback returns a share of net losses. Rakeback is consistently better value for active players.
- Forgetting that RTP is long-run. A 99% RTP game still has variance. RTP describes average over millions of spins, not the expected result of your session.
- Assuming PWA equals app-store-app. A PWA is a browser-installed web app; an app-store app is a binary. Both behave like apps, but the trust and update paths differ.
FAQ
Why so many acronyms? The gambling industry and the crypto industry both run on jargon. Crypto casinos sit at the intersection. Casino, payments, regulation and crypto each contribute its own vocabulary.
How do I check a term I don't see here? The casino's help centre and terms of service typically define operator-specific terminology. Wikipedia and the Cambridge Online Dictionary cover generic gambling and crypto terms. Reddit r/cryptocurrency and r/onlinegambling for community-sourced explanations.
Are there standard definitions across operators? Generally yes for the technical terms (RTP, house edge, provably fair) and the regulatory terms (KYC, AML, GGR). Bonus terms vary substantially — WR base, max bet, eligible games change per operator.
What is the difference between casino jargon and crypto jargon? Casino jargon covers game mechanics, bonus structures, regulator filings, and operator product. Crypto jargon covers blockchain mechanics, wallets, tokens, networks. Crypto casinos blend both — a "no-KYC USDT-TRC20 provably fair Originals" sentence makes sense only if you know both vocabularies.
What is the most misunderstood term? Wagering Requirement — specifically the deposit-plus-bonus base versus bonus-only base distinction. The single largest source of player disputes at every operator.
