1. General betting principles

By placing a bet through Mateslots Casino, you confirm that you have read and understood the rules that apply to the relevant product. You also confirm that you are permitted to use the service under the laws that apply to you. It is your responsibility to check whether online gambling is lawful in your location before creating an account or placing a bet.

These rules apply to bets placed through the website or any other approved access method made available by Mateslots Casino. Different games, events or markets may have additional rules. Product-specific information displayed on the relevant betting page forms part of the terms for that bet. If a product rule conflicts with a general rule, the product-specific rule will generally apply to that product.

You must use your own account and provide accurate, current information. An account must not be shared with another person, and you must not place bets on behalf of someone else. Mateslots Casino may carry out account, identity, payment or security checks where required by its procedures or applicable obligations.

  • Only one person may use an individual player account.
  • You must keep your login details secure and tell Mateslots Casino promptly if you believe your account has been accessed without permission.
  • You must not use the service for unlawful activity, fraud, manipulation or any attempt to interfere with the operation of a game or betting product.
  • You must not use automated tools, bots, scripts or other methods designed to gain an unfair advantage unless expressly permitted.
  • You should check the bet details carefully before confirming a wager.

Mateslots Casino may refuse, restrict, suspend or review a bet or account where this is necessary for security, compliance, responsible gambling, technical or operational reasons. Any action taken will be handled in accordance with the applicable Terms and Conditions and relevant procedures.

2. Placing and accepting bets

Checking your selection

Before confirming a bet, check the product, selection, stake, odds or payout information and any other details shown on the confirmation screen. Once submitted, a bet may not be changed or cancelled unless the applicable product rules allow it. A bet is not necessarily accepted simply because it has been entered on a bet slip or appears to have been submitted.

When a bet is accepted

A bet is accepted only when it has been recorded by the Mateslots Casino betting system and an appropriate confirmation or record is shown in your account. If a bet does not appear to have been accepted, you should not assume that it has been placed. You should review your account activity before attempting to submit the same bet again.

The availability of a product, market, game or selection does not guarantee that a bet will be accepted. Bets may be declined, limited or subject to review. This can occur because of technical problems, market changes, account restrictions, responsible gambling controls, suspicious activity or other operational reasons.

Stake and account balance

You may place a bet only when the required funds are available in your account and the bet is permitted by the relevant product rules. The amount shown as your stake is the amount associated with that bet. You should not place a bet using funds that you need for ordinary living expenses or other financial commitments.

Displayed odds, potential returns, bet limits and other information may change before a bet is accepted. The details recorded at acceptance are the details used for settlement, subject to corrections under these rules. Any promotional offer, bonus or special feature is governed by its own conditions and is not automatically included in the general rules.

Odds and displayed information

Odds and payout information are provided for information before confirmation and may be displayed in different formats depending on the product. The potential return shown may include the original stake or may show the profit only, so you should read the labels and product information carefully. If you are unsure how a price, return or payout is calculated, do not confirm the bet until you understand it.

3. Settlement, corrections and cancellations

How bets are settled

Bets are settled using the result, outcome or other settlement information applicable to the relevant product. For event-based betting, settlement may depend on an official result or another reliable source identified in the product rules. For games, the result generated or recorded by the relevant game system will normally determine the outcome. You should review the rules for the particular product because settlement methods can differ.

If an event is abandoned, postponed, interrupted, changed or completed under unusual circumstances, the relevant product rules will determine whether a bet remains valid, is settled in another way or is cancelled. A selection may also be treated as void where the required conditions for settlement are not met.

Errors and incorrect information

Mateslots Casino aims to keep its betting information accurate, but errors can occur. An error may include an incorrectly displayed price, return, result, market status, selection, stake, settlement or account balance. If a clear or obvious error affects a bet, Mateslots Casino may correct the error, recalculate the bet using the correct information, void the affected bet or take another reasonable action permitted by the Terms and Conditions.

If you notice an error, you should stop using the affected product and report the issue through the available support process. You must not deliberately take advantage of a known error or continue placing bets after becoming aware that information may be incorrect. Any funds credited as a result of an error may be reviewed and, where permitted, reversed or recovered.

Cancellations and account review

A bet may be cancelled or voided when required by the product rules, because of a technical or processing problem, or because the bet was affected by an error, prohibited conduct or an event that cannot be settled normally. Cancellation does not necessarily apply to every bet on an account or every selection in a multiple bet. The outcome will depend on the circumstances and the applicable rules.

Where an account or transaction is under review, settlement or access to related funds may be delayed while the review is completed. Mateslots Casino may request information or documents needed to verify activity, protect the account or meet applicable obligations. You must provide information that is accurate and not misleading.

Checking your records

You should regularly check your bet history, account balance and transaction records. Keep a record of any issue you wish to raise, including the date, product, stake, selection and confirmation details. If you believe a bet has been settled incorrectly, raise the matter promptly through the available customer support channel so it can be reviewed against the account and system records.

4. Responsible gambling, fair play and updates

Play within your limits

Gambling should be treated as entertainment, not as a way to earn income or recover financial losses. Set a budget before you play and decide how much time you are comfortable spending. Never chase losses, borrow money to gamble or continue playing because you feel pressured to win back money. Take regular breaks and stop if gambling is no longer enjoyable.

  • Set personal spending and time limits where those tools are available.
  • Use account restrictions, breaks or self-exclusion options if you need time away from gambling.
  • Do not gamble when you are upset, under the influence of alcohol or drugs, or unable to make clear decisions.
  • Seek independent support if gambling is affecting your finances, relationships, work or wellbeing.
  • If you are concerned about another person’s gambling, encourage them to seek appropriate assistance.

Fair and permitted use

All bets must be placed fairly and for legitimate personal use. You must not manipulate outcomes, exploit vulnerabilities, use another person’s payment method without permission or engage in conduct that may compromise the integrity of a product. Mateslots Casino may investigate unusual activity and take action under its Terms and Conditions where there is a concern about fraud, abuse, collusion or other prohibited conduct.

Changes to these rules

These Betting Rules may be updated from time to time to reflect changes to products, systems, legal requirements or operating procedures. The current version published on the website applies to future bets from the time it takes effect, unless a different arrangement is required by law or stated in the relevant notice. You should review the rules regularly and before using a new product.

If you have a question about a specific bet, review the product rules and your account records first. For further assistance, use the customer support options made available on the website. If you cannot resolve a concern, follow the complaints or dispute process described in the Terms and Conditions.

By continuing to use Mateslots Casino, you acknowledge that betting involves risk and that you are responsible for understanding the rules that apply to each wager. Only bet what you can afford to lose, and stop playing whenever gambling no longer feels safe or manageable.
