The Games at Crypto Casinos: Three Families, and How Each Enters the Score

Three families, and where each sits on the scale

• Studio slots — Built by: Outside developers · Checked by: Studio-arranged testing and a published RTP · Points on the scale: None
• Live dealer tables — Built by: Studios that stream real tables · Checked by: Real cards and wheels in shot, plus studio procedures · Points on the scale: None
• In-house originals — Built by: The operator · Checked by: A provably fair check, if the operator offers one · Points on the scale: Criterion 6, 5 points, if the tool works

The first two rows are the same products at a crypto operator as at a Gambling Commission licensee, which is why they score nothing: a lobby cannot distinguish itself by carrying what every lobby carries. The third row is the family a crypto operator builds itself and the only one a player can check, which is why it has a criterion of its own and why the criterion is small.

Studio slots: the same game, a different frame

Slots are licensed in from developers who publish a return-to-player figure and arrange the testing. A familiar title at a crypto casino is usually the same game on the same studio servers with the same published return. The operator's control stops at the edges of the game: it picks the titles in the lobby, chooses a return setting when a studio supplies more than one, and decides how much each title contributes to bonus wagering.

Tap the "i" icon and the panel lists the return figure for the active setting, volatility if stated, the top win and the bet range. Check it on the operator's own site, not in a third-party review, since the operator picks the setting. Look too at the highest bet allowed: at an overseas operator, that ceiling is where you see that no licence cap applies.

The scale records none of this, and deliberately. A lobby of several thousand titles is not safer or fairer than one of several hundred, and a high return figure means little if the operator sits on withdrawals: you have a generous game and perhaps no payout. The regulator on the card decides the second question, and criteria 1 to 5 score it.

Live tables: the studio's round, the operator's balance

In a live game a human dealer runs a physical table in a studio, streamed into the lobby. Overseas sites usually offer more of these than licensed UK ones, and more variants: plain roulette and blackjack at one end, game shows with wheels and multipliers at the other. Fairness comes from the real equipment in shot and how the studio runs it. The operator hires the tables, fixes the limits and keeps your balance.

In practice, two things matter: no licence caps the table limits at an overseas operator, and live play usually adds little or nothing towards a bonus. On our scale, live tables earn no points for the same reason slots earn none: whichever operator rents the table, the studio is the one running the round.

Originals: the family the operator builds and the player can check

Dice, crash, mines, plinko, limbo and similar games are written by the operator and hosted on its servers. They are the fastest games in a lobby, the ones bonus terms most often exclude, and the only ones whose rounds a player can check.

The method. Ahead of each round, the game shows its server seed in hashed form, a one-way fingerprint that locks in a value while keeping it hidden. You set or are shown a client seed. Both seeds, plus a nonce counting the rounds, produce the outcome. Afterwards, or once you switch to a new seed, the game discloses the server seed: hash it, match it to the fingerprint and recalculate the outcome. A match shows the result was locked in before you bet and stayed that way.

What it does not prove. A low house edge, for one: that figure is published separately. It tells you nothing about studio games or live tables either, and nothing about the cashier or the operator behind it. A verifiable round at an operator with no licence in any register is a fair round you cannot collect. That is why criterion 6 is worth five points and criterion 1 is worth forty.

How criterion 6 is scored. Only where the operator claims provably fair games, and only for whether a verification tool exists and ran when we tested one round. The leading UK guides recommend a check after each session instead of after every round, and that is enough to spot a swapped seed. To be sure the operator's own tool is honest, though, you have to run one round through an independent hash calculator at least once; nothing else confirms it.

Crash, specifically

In a crash round a multiplier climbs upwards from one and halts at a point set before play began. Your stake goes in before the climb, and you may cash out whenever you like until it halts. You collect the multiplier showing when you cashed out, or lose the stake if you had not cashed out by then. Because the provably fair seeds determine where it stops, the hash published beforehand binds the operator to that point.

Two consequences follow. First, the house takes the same fixed share of each round, so no timing of the cash-out alters the expected return. Second, a round lasts seconds, and auto-cash-out settings let play run on without any effort from you. That second point is why the deposit cap scored under criterion 7 should be set before the first round, not after it.

The stake rule: the one game-level difference the licence makes

Online slot stakes at Gambling Commission licensees are limited to £5 per spin if you are 25 or older, and to £2 if you are between 18 and 24. Overseas operators set no limit at all.

Slots players feel this more than any gap in the game list; nothing else separating the two kinds of lobby comes close. It works in both directions. The missing cap pulls high-stakes players towards overseas sites, and the Commission lists that movement among the harms of unlicensed gambling. The cap also alters bonus maths: with a £5 ceiling, £1,000 of wagering takes 200 spins or more, while without one it can take far fewer.

The rule enters the scale under criterion 1 rather than under games, because it is a licence condition and not a lobby feature. A licensee applies it by construction; an overseas operator cannot apply it even if it wished to, since the condition exists only inside the licence.

Bonus contribution: which lobby an offer confines you to

A bonus is a liability whose size rests on four terms: the wagering multiple, the top stake while it runs, the contribution of each game family and the expiry date. If games brought you here, read the contribution figures first.

Take an invented example: a bonus valued at £50 at today's rate, with 40x wagering on the bonus amount. Slots count 100 %, live tables 10 % and originals 0 %. Played through on slots, it takes £2,000 in stakes. On live blackjack the figure is £20,000. On crash you can never clear it, and asking for a withdrawal cancels it. One headline, three very different lobbies.

Criterion 5 scores whether the contribution table is visible within a click of the offer, not what it says. Under its licence, a Gambling Commission operator cannot ask for wagering of more than ten times the bonus, and the significant terms have to be one click away. An overseas operator chooses its own terms, and the card quotes them with the date.

What the cards record about a lobby

• Provably fair tool: works, absent, or not claimed. Criterion 6.
• Contribution table within a click: yes or no. Criterion 5.
• Studio families present, live tables, originals, crash: noted, not scored.
• Demo play open without an account: noted. A licensee cannot offer it, because the licence requires age verification before free-to-play games; an overseas operator usually does.

A reader who came for the games will find the lobby fields on every card. A reader who wants to know whether a win will be paid will find the answer under criterion 1, and this page has tried to say why those are different questions. Gambling in Great Britain is for adults aged 18 and over. If it is causing you harm, call the National Gambling Helpline, which GamCare runs: 0808 8020 133, free, day or night.
