Bonus winnings removed? Build a dispute around the terms and bet history

A completed wagering counter does not tell you why a casino removed winnings. The dispute may concern an excluded game, a maximum stake, an expired promotion or the way different balances were used. Before arguing about the final number, establish the specific promotion and the rule the operator says was breached. Your strongest starting point is a small set of matching records: the accepted offer, the relevant terms and the transactions.

Bonus disputes are also the area where players most often turn out to have broken a rule without realising it. That does not make every deduction fair, but it does mean the strongest complaints are precise ones. Show exactly which part of the decision you dispute, and acknowledge what you do not.

Identify the offer you actually accepted

Save the promotion name, acceptance date, offer email or account notification, and the terms shown at that time. A current welcome-offer page may describe a different campaign. If you do not have the historical wording, ask the operator to provide the version it applied to your account. Explain the gap instead of assuming today's wording was in force when you played.

Note whether you actively accepted a bonus, received free spins or had a reward credited automatically. Record any opt-out, cancellation or support promise. Do not rely on the size of the headline offer to explain the disputed balance; a nominal bonus and winnings produced during bonus play are separate amounts.

Separate your deposit, bonus and winnings

Write down the deposit amount, bonus credited, balance before the deduction and amount removed. If the account provides separate cash and bonus wallets, capture both. If it shows only one total, request a breakdown rather than deciding that all of it must be cash or all of it must be promotional. A useful response explains how the operator calculated the balance it is retaining.

Item	Example	Where to find it
Deposit	€100 on 2 October	Bank statement and casino transaction history
Bonus credited	€100 match bonus	Bonus or promotions tab, offer email
Balance before deduction	€1,340	Screenshot, account statement
Amount removed	€1,240	Transaction history, support message
Amount left or returned	€100	Balance after deduction

For the British regulated market, the Gambling Commission distinguishes deposit funds from restricted bonus funds and describes protection for withdrawals of deposit balances, subject to applicable regulatory obligations. Its bonus guidance also addresses clarity of restrictions. These are jurisdiction-specific rules, not a promise that any offshore bonus balance is immediately withdrawable.

The clauses most often invoked, and what to ask for

Maximum bet while a bonus is active

Many offers cap the stake per spin or round while wagering is incomplete. Ask for the bet identifier, timestamp, stake and game of each bet said to exceed the cap. Check whether the cap applied to the whole bonus period or only part of it, and whether the cashier or game warned you.

Excluded or reduced-contribution games

Terms often exclude certain games or count them at a lower rate. Ask which entry in the game list covers the game you played, and whether that list was available when you accepted the offer. A game added to the excluded list later is worth raising.

Maximum cash-out from a bonus

Some offers, especially free spins and no-deposit bonuses, cap what can be withdrawn. If the deduction equals your balance minus a fixed figure, a cap may be the explanation. Ask for the clause and check that it appeared in the offer terms rather than only in general terms.

Expiry

Ask for the expiry time and its time zone. If you were playing close to the deadline, a difference of a few hours in time zone can matter.

Bonus abuse, low-risk play or multiple accounts

These are broad allegations. Ask what specific pattern was detected: betting on both outcomes, switching to low-variance games after a win, or linked accounts. Respond to each concrete point, and take care not to overstate; if you did play in the way described, argue about whether the term clearly prohibited it rather than denying the play.

Ask for the rule and the transaction together

If the reason is a maximum-bet breach, ask for the bet identifier, timestamp, stake, game and balance used. If an excluded game is alleged, ask which entry in the applicable game list covers it. If wagering was incomplete, request the contribution calculation rather than only a percentage. Each question tests a concrete link between a rule and the account history.

Review the reply against your records without changing them. A single screenshot of a winning round may not show the transaction the operator is challenging. Ask for the surrounding sequence where necessary. If a game feature creates several linked transactions, such as a bonus buy or gamble feature, explain why the stake display and history may appear different and ask the operator to identify the entry it used.

Check the arithmetic before the argument

Work through the published requirement using the offer's own definitions. Does the multiplier apply to the bonus alone or to the bonus plus deposit? Do all games contribute equally? Which transactions were excluded? Write a short calculation and label it as your own.

For example, a €100 bonus with a 30× requirement on the bonus alone needs €3,000 of eligible wagering. If slots count at 100% and table games at 10%, €2,000 on slots and €5,000 on blackjack contribute €2,000 and €500, leaving €500 to go. If the same terms apply 30× to bonus plus deposit, the requirement doubles to €6,000. Mistakes like these explain many disputes, on either side. Ask the casino to identify the point where its calculation differs from yours.

British promotional rules introduced on 19 January 2026 cap bonus wagering requirements at ten and prohibit offers requiring participation across multiple gambling products. The announcement was corrected from an earlier implementation date. When invoking that change, identify the date of your offer and the British licence; do not cite it as a worldwide limit or assume it decides an older dispute.

When the terms themselves are the problem

Sometimes the facts are agreed and the dispute is about the wording. A rule may be buried in general terms rather than the offer terms, phrased so vaguely that it could cover almost any play, or changed after you accepted the promotion. Quote the exact sentence, say where it appeared, and explain why a reasonable player would not have understood it to prohibit what you did. Avoid claiming that a term is unlawful unless you can point to a rule in the operator's market that supports it.

If you were credited a bonus you did not ask for, say so and show what the opt-in looked like. An automatic bonus that attaches wagering rules to your own deposit is a different argument from a bonus you knowingly accepted.

Free spins and no-deposit offers

Free spins and no-deposit bonuses carry their own conditions, which are often stricter than deposit bonuses. Winnings from free spins are usually credited as bonus money with a separate wagering requirement, and many no-deposit offers cap the amount that can be withdrawn. Some also require a small verification deposit before any withdrawal. Ask whether the winnings were converted to bonus funds, what requirement applied, and whether a cap reduced the payable amount. Check that the cap appeared in the offer terms you saw, not only in a general section you were never directed to.

What a realistic outcome can look like

Not every bonus dispute ends with the full balance reinstated. Outcomes recorded in public cases include a written explanation that shows the rule was clearly disclosed, a return of the original deposit, reinstatement of winnings from bets that did not breach the rule, and full payment where the operator could not support its decision. Deciding in advance which of these you would accept, and which part you would continue to dispute, makes it easier to respond to an offer without being pressured into closing the whole matter.

Make the complaint about the disputed decision

Keep the opening short: identify the amount removed, date, promotion and stated reason. Explain whether you dispute the factual allegation, the calculation, the wording of the restriction or how it was communicated. Those are different arguments. If you acknowledge a transaction but believe the term was unclear, say so rather than claiming the transaction never happened.

Ask for the relevant terms version, supporting transactions, balance breakdown and a written final position. If the operator offers to return a deposit while removing bonus winnings, record both parts. You may accept one undisputed payment while another issue remains, but read any settlement wording before agreeing that the entire matter is closed.

Preserve the claim without gambling more

Do not continue playing simply to make a disputed wagering figure move. New play can alter balances and muddy the earlier calculation. Save these records privately:

• The offer email or notification and the terms version in force when you accepted it.
• Your balance before and after the deduction, with dates.
• Bet history for the bonus period, exported or screenshotted with timestamps.
• The operator's message naming the rule, and any follow-up explanations.
• Your own wagering calculation, clearly labelled as yours.

Publish only redacted excerpts that show the decision, not your full personal profile. The evidence guide explains how to retain context while removing private information.

If support repeats a conclusion without addressing the transaction or term, use the formal complaint route and then the relevant external process; the ADR and regulator guide explains how to select it. Before filing on CasinoComplaints.org (how it works explains what the team checks), look the operator up on Check casino to see whether the same clause appears in other cases, and check the blacklisted casinos list for recorded patterns. A public complaint can make the exchange easier to follow, but it cannot turn an unverified allegation or an ambiguous rule into a guaranteed award. If the bonus issue is also holding up a payout, the withdrawal guide covers the payment side.
