These Terms & Conditions govern your access to and use of the mbak4 platform, including all casino games, sportsbook services, account management features, promotional offers, and payment processing. Please read this document carefully before registering an account or placing any wagers.
You must be at least 21 years of age and a resident of Indonesia to register and use mbak4. Underage use is strictly prohibited and will result in permanent account closure.
Each member is permitted exactly one mbak4 account. Duplicate accounts will be closed and associated balances forfeited. Identity verification may be required at any time.
All transactions are processed in Indonesian Rupiah (IDR). Accepted channels include BCA, BRI, BNI, Mandiri, CIMB Niaga, OVO, DANA, GoPay, ShopeePay, and LinkAja.
All promotional bonuses are subject to wagering requirements. Bonus terms are published plainly on each promotion page. Abuse of bonuses may result in account suspension.
In these Terms & Conditions, the following defined terms have the meanings set out below unless the context otherwise requires:
By accessing the Platform, completing the registration process, logging into an existing Account, or using any of the Services, you acknowledge that you have read, understood, and agree to be legally bound by these Terms & Conditions, together with the Privacy Policy and the Responsible Gaming Policy, each of which is incorporated herein by reference.
If you do not agree to any part of these Terms & Conditions, you must immediately cease using the Platform and close your Account by contacting our support team. Continued use of the Platform following notification of any amendment to these Terms & Conditions constitutes acceptance of the revised terms.
These Terms & Conditions are written in English. In the event of any inconsistency between an English version and any translated summary, the English version shall prevail.
Use of the mbak4 Platform is restricted to individuals who satisfy all of the following eligibility criteria at the time of registration and at all times during use of the Services:
mbak4 reserves the right to request proof of age and identity at any time. Any Member found to be under 21 years of age will have their Account immediately suspended, all pending withdrawals cancelled, and any winnings forfeited. Real-money deposits made by underage users will be returned to the originating payment method where technically possible.
To access real-money gaming and sportsbook services on the mbak4 Platform, you must complete the registration process and create an Account. The following conditions apply to Account registration and ongoing account maintenance:
You agree to provide accurate, current, and complete information during registration, including your full legal name, date of birth, residential address in Indonesia, valid email address, and mobile phone number. You further agree to update this information promptly if it changes. mbak4 bears no liability for Account access issues or transaction failures arising from inaccurate or outdated registration details.
You are solely responsible for maintaining the confidentiality of your Account username and password. You must not share your login credentials with any other person. All activity conducted through your Account — whether or not you authorised it — is your sole responsibility. If you suspect that your Account has been accessed by an unauthorised party, you must notify mbak4 support immediately at [email protected].
Each individual is permitted to hold only one registered Account on the mbak4 Platform. Opening multiple Accounts ("duplicate accounts") — whether under the same or different names, email addresses, or payment methods — is strictly prohibited. mbak4 employs automated and manual detection methods to identify duplicate accounts. Where duplicate accounts are identified, mbak4 reserves the right to close all associated accounts, forfeit any Bonus Credits, and retain winnings derived from promotional play across the duplicate accounts.
mbak4 strongly recommends that all Members enable two-factor authentication (2FA) on their Account. You must not use the Platform from a shared or public device without logging out completely after each session. mbak4 will never ask for your password via email, live chat, or any other channel.
mbak4 is required under its international licensing obligations to verify the identity and age of its Members. KYC verification may be requested at registration, prior to a Member's first withdrawal, or at any time mbak4 deems appropriate in accordance with its compliance procedures.
You may be required to submit one or more of the following documents:
mbak4 aims to complete standard KYC reviews within 24–48 hours of receiving all required documents. During a pending KYC review, deposits may continue to be accepted; however, withdrawals will be held until verification is successfully completed. mbak4 accepts no liability for any delay in withdrawals caused by incomplete or incorrect KYC submissions.
If a Member refuses to submit requested KYC documentation, or if submitted documents cannot be verified as authentic, mbak4 reserves the right to suspend the Account, freeze any Wallet Balance pending investigation, and ultimately close the Account if satisfactory documentation is not provided within 14 calendar days of the initial request.
mbak4 accepts deposits and processes withdrawals via the following Indonesian payment channels: BCA, BRI, BNI, Bank Mandiri, CIMB Niaga, BSI (Bank Syariah Indonesia), Bank Permata, and the e-wallets OVO, DANA, GoPay, ShopeePay, and LinkAja. All transactions are denominated in Indonesian Rupiah (IDR). mbak4 does not charge transaction fees on standard deposits or withdrawals; however, your bank or e-wallet provider may impose their own fees, for which mbak4 bears no responsibility.
Minimum deposit amounts start from Rp 25.000 for bank transfers and Rp 10.000 for e-wallet transactions. Minimum withdrawal amounts and maximum daily/weekly withdrawal limits are displayed in the cashier section of your Account and may vary depending on your membership tier and KYC status. mbak4 reserves the right to adjust these limits at any time with reasonable notice.
Withdrawal requests submitted before 20:00 WIB on a business day are typically processed within the same business day. Requests submitted after 20:00 WIB or on Indonesian public holidays (including Idul Fitri, Idul Adha, Independence Day, Nyepi, and other gazetted national holidays) will be processed on the next available business day. mbak4 targets a withdrawal processing time of under 3 hours for verified Members.
Withdrawals must be returned to the same payment method used for the original deposit where technically possible. mbak4 does not process withdrawals to third-party accounts, accounts held in names other than the registered Member name, or payment methods not previously used to fund the Account. These restrictions exist to prevent money laundering and protect Member funds.
An Account that has not recorded any login activity for a continuous period of 12 months will be classified as dormant. mbak4 will make reasonable efforts to notify the Member at their registered email address before applying a dormancy administration fee of Rp 50.000 per month. Members may reactivate a dormant Account by logging in and completing any outstanding KYC requirements.
All bonuses, free spins, cashback awards, reload offers, and promotional credits offered by mbak4 are subject to the specific terms published on each individual promotion page, as well as the general bonus conditions set out in this clause. In the event of any conflict between promotion-specific terms and these general terms, the promotion-specific terms shall prevail.
Unless otherwise stated on the relevant promotion page, all Bonus Credits are subject to a wagering requirement before they or any associated winnings may be withdrawn. Wagering requirements are expressed as a multiplier of the bonus amount (for example, "30x" means the bonus amount multiplied by 30). Contributions toward wagering requirements vary by game type: slots generally contribute 100%, live casino games typically contribute between 10% and 15%, and certain game types may contribute 0%. Full contribution rates are published on each promotion page.
mbak4 operates a zero-tolerance policy toward bonus abuse, which includes but is not limited to: claiming bonuses across multiple duplicate accounts; using betting strategies that exploit bonus terms without genuine engagement in normal gameplay; arbitrage betting using bonus funds; or colluding with other Members to collectively exploit promotional offers. Where bonus abuse is detected, mbak4 reserves the right to void all Bonus Credits, forfeit any winnings derived from bonus funds, and permanently close the associated Account(s) without further notice.
New Members who complete registration and make their first qualifying deposit may be eligible for a Welcome Bonus as advertised at the time of their registration. The Welcome Bonus is available once per Member, per household, per device, and per IP address. Eligibility, bonus percentage, maximum bonus amount, minimum qualifying deposit, and wagering requirement are specified on the promotion page active at the time of registration.
mbak4 may offer special promotions coinciding with Indonesian cultural and national events including Idul Fitri, Idul Adha, Ramadhan, Nyepi, Independence Day (17 August), and other occasions. These promotions are subject to their own specific terms and are available for a limited time only. mbak4 reserves the right to withdraw or modify any seasonal promotion at any time without prior notice.
All games available on the mbak4 Platform — including live casino tables, slots, crash games, card games such as Capsa Susun (a Chinese poker variant popular in Indonesia), Roulette, and sportsbook markets — are governed by individual game rules published within each game's interface or on the relevant product page.
