Is this legal advice?

No. OASIS and LUGAS notes describe how GGL brands work in our reviews. Your situation still depends on residence, a live ban entry and the operator. The German OASIS guide is longer; it is not an invitation to evade a ban.

Where do I compare casinos after I know the terms?

Best-casinos and the Germany list. Payment hubs (bank transfer, not Interac from DE) sit next to KYC when money moves.

Glossary

Casino glossary

Plain-language notes on wagering, RTP, KYC, OASIS and LUGAS.

Last checked 27 Aug 2026Affiliate disclosure18+ / play responsibly

This glossary is for people comparing casinos on Rehanak, not a law textbook. Five terms show up in almost every review: wagering, RTP, KYC, OASIS and LUGAS. The first three apply everywhere we list a brand. The last two are Germany-specific and are why a Curaçao lobby in German is not the same product as a GGL whitelist casino.

Each card below is a one- or two-sentence definition plus a link to the full note. Use the full pages when you need examples (40x on €100, 96% RTP vs a session, OASIS vs an offshore skip). Internal links go to bonus tools, Germany lists and the OASIS guide — not to a second copy of the same paragraph.

Next: casino comparison, KYC, LUGAS, bank transfer.

How to use this glossary

Start with the group that matches the page you came from: bonus math, slot info screens, cashier delays, or German regulation.
Open the term page for the worked example. Then jump to the related tool (bonus calculator, Germany list, OASIS guide) instead of rereading marketing copy.
Figures on casino reviews are snapshots. If the cashier and this glossary disagree, the cashier and T&Cs win.

Bonuses and playthrough

How welcome offers actually cost you once the multiple, game weighting and max bet sit next to the headline.

Wagering

A 40x bonus on €100 means €4,000 of bets before cashout, subject to game weighting and max-bet rules.

Open term

Game math

Long-run return is a studio figure, not a session promise. Volatility and GGL stake caps sit beside it.

RTP

A 96% RTP slot is built to return about €96 per €100 staked over a huge number of rounds. Short sessions can be far above or below that.

Open term

Identity and payouts

Advertised “instant” cashouts start after documents clear. Closed brands are why we keep a closed list.

KYC

Expect ID, proof of address and payment-method ownership. First cashouts are often slower than advertised “instant” times until KYC clears.

Open term

Germany: OASIS and LUGAS

Self-exclusion and the shared monthly deposit cap on GGL brands. Offshore German copy is not a whitelist.

OASIS

If you are in OASIS, legal German online casinos must refuse you. Offshore sites that skip OASIS are not a safe workaround.

Open term

LUGAS

On GGL brands, deposits across providers share a monthly ceiling. Raising it is a formal process, not a cashier toggle.

Frequently asked questions

These five decide whether an offer is usable (wagering), whether a RTP figure means anything in a session (it does not), whether a payout clock has started (KYC), and whether a German-language site is actually legal play (OASIS/LUGAS). We add terms when they show up in reviews, not to pad the hub.
