Mines game: in-house titles and who to ask

A mines game is almost always an in-house title rather than licensed studio content, and that single structural fact decides what can ever be checked about it. When a studio builds a game, there is a third party who could publish its mathematics. When the operator builds it, the maker and the counterparty are the same company, and the only external check on offer is a recomputation scheme. Our library does not hold a mines game record, a grid size or a multiplier, and will not invent one. What it does hold is the tag structure underneath that difference, and that structure is worth a page.

Two tags, and what each one actually records

Every record in our hundred-brand library carries a tag list copied from the operator’s own pages, with a read date. Two of those tags matter here.

original-games appears on 20 records. It records that the operator’s own pages present in-house titles as a category distinct from licensed studio content. It does not name a title, count them, or say who wrote the code.

provably-fair appears on 21 records. It records that the operator’s pages present a scheme for recomputing a finished round from a seed pair. It does not say the scheme covers every title, and it does not say we tested it.

Neither tag will ever tell you whether a mines game exists at a given brand, because there is no title field anywhere in the schema to hold the answer. What the two tags do between them is split the library into groups that behave differently, and the groups are the interesting part.

The twelve, the eight and the nine

Twelve records carry both tags: BC.Game, Bitsler, DuckDice, Flush, JacksClub, Metaspins, Rainbet, Rakebit, Shuffle, Thunderpick, Wild.io and Wolf.bet. These are the brands whose own pages both present in-house titles and offer a way to recompute a round. If you are going to play a mines game anywhere, this is the group where an external check is at least claimed.

Eight records carry the in-house tag with no fairness tag: BetFury, Bitcasino.io, BitStarz, Fairspin, Punt Casino, Rocketpot, SolCasino and TrustDice. In this group the operator presents its own titles and does not present a recomputation scheme, which means that on our reading there is no published route for a player to check a finished round at all.

Nine records carry the fairness tag without the in-house tag: Bspin, Cloudbet, CryptoGames, KatsuBet, LTC Casino, Mega Dice, Mirax, Primedice and Stake. Here a scheme is presented over content that, so far as the tags go, comes from studios.

Those three counts are the most useful thing we can say about the format. They are not a ranking and they are not a safety rating: they are a map of where a claim of checkability has been made and where it has not.

The eight without a recomputation claim, read one by one

The group with in-house titles and no fairness scheme deserves its licence rows spelled out, because they vary more than the tag suggests.

• Bitcasino.io — Curaçao Gaming Authority OGL/2023/111/0069, Moon Technologies B.V., company number 152185, granted 1 July 2024, Active on 26 August 2026. Rated 7.5. States additional checks above 2,500 euro, clause 6.6.
• BitStarz — OGL/2024/165/0185, Gareton B.V., company number 160656, granted 8 July 2024, Active. Rated 6.1. Its terms make verification an obligatory procedure covering identity, payment and address, with 74 refused countries published.
• BetFury — OGL/2024/1494/0942, Universe B Games B.V., company number 155126, granted 31 July 2025, Active. No rating: the verification cell in its record is empty, because we could not read a clause. Its catalogue capture is one of the largest we hold, at 74 supplier strings.
• Rocketpot — licence recorded as 1668/JAZ under Danneskjold Ventures B.V., which our scoring file marks as claimed but not confirmed in a register, costing it 1.7 of the 2.5 licence points. Rated 7.2 anyway, on the strength of a stated threshold at clause 11.4.
• Fairspin — Anjouan ALSI-202508047-FI2, Sorta Group Limitada, valid, issued 18 August 2025, expiring 17 August 2027. Rated 4. Documents must be supplied within five days of a request, clause 7.6, the shortest deadline in the library.
• TrustDice — OGL/2024/664/0280, Satoshi Gaming Group N.V., Active, and a second entry in the Anjouan register under Satoshi Labs Ltd. Unrated: only two components carried data.
• Punt Casino — no licence fields filled. The Curaçao portal’s response for punt.com reads that a certificate of operation is not valid. Unrated.
• SolCasino — no licence fields filled, and the same not-valid response for solcasino.io. Unrated, and the verification cell is empty too.

Four register-confirmed licences, one claimed-but-unconfirmed, two not-valid responses and one dual entry, inside a single tag. That is the reason we publish parts rather than badges, and the reason a tag is never the end of a check. How those portal responses differ from one another is set out in the six answers a certificate portal can give.

What a recomputation claim is worth for a mines game

The scheme the fairness tag points at lets a player take a finished round, combine the server seed with the client seed, and confirm that the outcome matches. Applied to a mines game, that would confirm the layout was fixed before the first click rather than after it. It is a real property and it answers a real worry.

What it does not do is publish the probabilities. A verified round tells you what happened once. It does not tell you the chance of clearing a given number of safe tiles, it does not tell you the expected return of any setting, and it does not license any claim about which setting is best. Those are distribution questions, and the distribution is not in our files for any title, in-house or otherwise. The mechanics of the check itself are covered in the seed-and-hash check written out in full.

There is also a coverage question nobody answers in writing. A brand can present a fairness scheme over its in-house titles while the rest of the lobby runs on studio content the scheme does not touch. Our tag records the presence of a claim, not its scope, and we have no field for scope. So the honest form of the sentence is narrow: twelve records present both in-house titles and a recomputation scheme, and how far the scheme reaches at each of them is unrecorded here.

When the maker is also the counterparty

The twelve-record group is where the structural point bites. The same company that wrote the mines game wrote the terms that govern the balance it pays into, and our files show what those terms reserve.

Rakebit is the clearest case, because its own documents disagree with each other. The terms of use require identity documents, a selfie and proof of address when a withdrawal is claimed for the first time, and allow verification at any time on fraud or money-laundering grounds; the separate KYC policy allows a check before a first deposit below 2,000 dollars if a payment provider asks. The homepage FAQ, read the same day, says standard withdrawals are processed without documents. We recorded the conflict rather than picking a side, because picking a side would have meant deciding which of the operator’s own pages to believe. Rakebit is rated 8.0 with a register-confirmed Anjouan licence, ALSI-202602030-FI2 under Nile King Media Ltd.

Shuffle reserves the right to request documents at any time and to restrict access or withdrawals until identity is established to its satisfaction, clause 4.1, with an anti-money-laundering policy that names a risk-dependent threshold and no amount. Metaspins requires verification once gambling reaches a threshold it does not state, clause 9.7, and reserves discretion besides. Wolf.bet may restrict service until identity is sufficiently determined, section 5, and its FAQ says verification is required for large withdrawals without naming a figure. JacksClub may ask at any time at its sole discretion.

Flush adds a term of a different kind: location masking is banned outright at clause 3.4, read on 27 August 2026. Its Anjouan licence, ALSI-202509008-FI1 under Fordegens Limitada, carries the note that the term ended on 2 September 2026 and has not been re-checked since — a row we leave standing with its date attached rather than quietly refreshing.

None of that is a criticism of in-house titles as such. It is the shape of the arrangement. When you play a studio game you have three parties and three sets of interests; when you play an in-house mines game you have two, and the discretion clauses above are written by the party that also set the odds. That is worth knowing before a session, and it is knowable, which is more than can be said for the payout curve. The ceilings that sit under the same signatures are collected in the withdrawal clauses recorded operator by operator.

An application is not a licence, and the portal says so

JacksClub sits in the group carrying both tags, and its register row is the one worth pausing on. The Anjouan public register carries ALSI-202507028-FI2 for Spades Limitada, valid, issued 15 July 2025 and expiring 14 July 2027. The Curaçao certificate portal, asked about jacksclub.io, answers differently: it reports the domain as operated by Jackfruit B.V., company number 157706, and states that the company has submitted an application for a licence and is not authorised to operate under Curaçao law. Both readings are from 26 August 2026.

So one brand, two jurisdictions, one valid licence and one open application under a different company name. Neither row says anything about a mines game, and that is the point: this is the level at which our evidence is actually sharp. A page that spent its length on grid strategies and skipped the registers would have missed the only checkable thing in the record.

Our rating gives JacksClub 6.5 of 10, built from the confirmed Anjouan licence, a published list of ten refused countries, a verification clause with no figure in it, and a zero for the sign-up component because documents are reserved from the start.

What would let us write a real page about the format

Three inputs, none of which we hold. A mathematics sheet for the specific title and configuration, published by whoever built it — which, for an in-house game, means the operator publishing figures about its own product. A dated capture showing the title live at a named brand. A round log long enough to test the sheet rather than take it on trust.

For studio content, the first of those is at least sometimes obtainable, because the studio is a separate company with a reason to publish. For an in-house mines game it is structurally harder, and that asymmetry is the one genuinely useful thing this page can add to the topic. It is also why the recomputation scheme carries more weight here than it would over studio content, and why we count the twelve and the eight separately rather than lumping them together.

Until those inputs exist, the same three sentences apply that apply everywhere on this site. We print the licence number, the holder, the status and the date we read it. We print the verification clause and its deadline where one is stated. We print the withdrawal ceiling and its clause. Everything else stays an empty cell, visibly, and the method behind that choice is described on the page setting out what this site reads. The records themselves, ordered by what we could verify rather than by what they claim, start at how studio lists feed the top no KYC casinos ranking.
