A failed or refused check means the funds are kept (20.1)
Checkpoint two: the operator's call
Six ranked casinos hold on to a right to ask for papers with no sum and no event attached. This page quotes the gist of each clause, what it lets the operator do, and what you can have ready.

A casino identity check at any time sounds like the opposite of what someone searching for a bitcoin site without verification wants to read. It is still the most common wording among the ranked operators: six of them keep a right to ask who you are without waiting for a withdrawal, a figure or anything else you did. Knowing that clause exists is worth more than any promise on a homepage.
Of the five checkpoints this site maps, this is number two, «whenever the operator decides». Below you will find the six clauses one by one, the difference between a right that names papers and a deadline and one that names neither, and a short list of things worth sorting out before the request lands. How this checkpoint fits among the other four is set out on the Bitcoin casino no verification page, which ranks the twelve casinos across all five.
Opening the account
What the sign-up form asks for, and papers some casinos want before play.
Whenever the operator decides
Clauses that let a check start at any point, with no sum and no event named.
Before money leaves
Clauses that tie the check to a withdrawal request.
Once a sum is reached
A written figure, a figure the terms mention but do not give, or what two real accounts met.
After papers are requested
The time you are given to send them.
Most terms combine several moments. A casino can ask for papers at sign-up, before money goes out, once a sum is passed, and also at a moment of its own choosing. The last kind swallows the others in practice: if the operator may ask on any day, then a quiet sign-up and a small balance only tell you that nobody has asked yet.
That is also why a casino identity check at any time outweighs a figure printed elsewhere in the same document, such as Bitcasino.io's €2,500 in clause 6.6: such a figure never works as a floor. The page on written sums goes through those figures. Here the question is narrower: which operators reserve the open-ended right, in which words, and what follows from it.
The ranking scores this under criterion two, «the moment the check can start». Rainbet, Metaspins and Bitcasino.io get the point because their clauses say when. Wolfbet, Thunderpick and Bitsler do not, since their wording leaves the moment open, and the checks table lets you compare all of them.

Rainbet, clause 20.1. Rainbet may ask for any document it needs, at any time, to establish who a user is and where. Four things appear on its list. There is the government photo ID, at times both of its sides, then a selfie of you holding it, a utility bill of recent date for your address, and a call to verify. The same clause sets your side of the bargain at 72 hours to supply what is asked, and a check you fail or refuse means the funds are kept. That combination is blunt, but everything is on the page: the trigger, the list, the clock and the result. The Rainbet review puts it next to its withdrawal rules.
Wolfbet, clause 5 §1. KYC and AML documentation may be requested at any time. Unlike Rainbet, Wolfbet stops there: its terms name no individual papers and set no deadline for sending them. Clause 5 §2 goes further in another direction. On suspicion, Wolfbet may withhold funds, and the clause says the player is not to be told. Clause 5 §3 adds that the account can be frozen or closed until the documentation arrives.
One Wolfbet rule is often mixed up with this. Before Wolfbet accepts a first withdrawal request, clause 15 §1 wants the email address confirmed and two-factor login switched on. That is a setting on your own account, not a check of who you are, and it is best sorted out on the day you open the account.
Thunderpick, clause 21.1. Papers are due when the operator requires them, and security questions can be put at its sole discretion. The documents named are a government-issued ID and proof of residency. No deadline appears, and no event or sum is tied to the request, which is why the checks table marks Thunderpick's moment as not given.
Bitsler, clause 4.3. Bitsler may ask for proof of age or identity to confirm the details given at sign-up, or to meet anti-money-laundering rules. Clause 8.22 adds large deposits or a level of spending that worries the operator, without a figure. Clauses 4.3 and 4.4 say an ID is wanted every time and, on some occasions, a utility bill or bank statement dated within the last three months, photographed with all four corners in view.
Metaspins, clause 9.7. Metaspins keeps the discretion to verify identity at any time and to hold payments until verification is done. The same clause says age is always verified and mentions «a certain threshold» of gambling without the number. Documents requested under Metaspins' clause 9.10 are due inside 30 days; past that point withdrawals are withheld and whatever balance remains can be confiscated. The Metaspins review covers its licence records as well.

Bitcasino.io phrases its open right differently. Clause 3.13 describes random account health checks that need no reason at all. It is the only clause among the six that says outright the selection can be random, which makes it the plainest statement that nothing you do is required to start a check.
The rest of Bitcasino.io's terms fill in the picture. Clause 5 keeps the right to ask for identity at the first deposit, though play does not wait for it. Clause 6.6 attaches a check to cash-outs over €2,500, or that much in crypto, and warns that lesser amounts can be checked as well. For papers, clause 6.5 wants a picture ID, evidence of your address, the debit card copied and something proving the payment instrument is your own.
What Bitcasino.io leaves out is a deadline for those papers, the single criterion it misses in the ranking. The checkpoint map shows how many of its moments stack up on one account.
For a reader comparing casinos, the practical point is simple. An open right means there is no balance, no date and no pattern of play under which a request is ruled out. What varies between operators is everything that happens after the request, and that part can be read before you deposit.
Put the six side by side and a pattern shows. Rainbet and Metaspins pair the open right with a stated deadline and a stated result. Bitcasino.io names its papers but not a deadline. Thunderpick and Bitsler name papers without a clock. Wolfbet names neither papers nor a clock, and adds a clause that lets funds be held without telling you.
«At our discretion» therefore does not tell you whether you will be checked; it tells you that the decision is not yours. The terms that then spell out the list, the time and the consequence are the ones you can actually prepare for. A plain look at what can be checked before a deposit takes the same approach to the licence and the papers.
Where a deadline is written, the same clause usually says what follows a miss. Among the six operators on this page, two print both:
Three more ranked operators set deadlines at other checkpoints. Vave allows 14 days under clause 8.7 and then closes the account and confiscates winnings. Wild Fortune allows two weeks for the documents under 8.4 and 9.3; if they are missing, it locks the account and cancels the pending request. Rocketpot counts 30 calendar days under 12.2, and then funds are frozen and play restricted.
The cards on this page set those five results out one under another. Wolfbet's clause 5 §3, freezing or closing the account until the documentation comes, reads like a result without a deadline. The documents and deadlines page holds the full list for every operator.
An open right cannot be timed, so the preparation has to come first:
Each point in that list is something that can be done now, while nothing is pending. How to spot the clause in a set of terms explains where to look if a casino you are considering is not on this list.
