To register and use big89, you must satisfy all of the following eligibility conditions at the time of registration and on a continuing basis throughout your use of the platform:
To open a big89 account, you must provide accurate, complete, and current information as prompted during the registration process, including your full legal name, date of birth, Indonesian mobile number, and preferred payment channel. You are solely responsible for ensuring that all information provided is truthful and up to date. big89 is entitled to rely on the information you provide and is not obligated to independently verify it except as required by its KYC procedures.
Upon registration, you will create a unique username and password. You are responsible for maintaining the confidentiality of your login credentials and for all activities that occur under your account. big89 strongly recommends enabling two-factor authentication (OTP to your registered Indonesian mobile number) and advises against sharing your password with any third party. If you suspect that your account has been accessed without your authorisation, you must notify big89's support team immediately via live chat.
big89 reserves the right to request identity verification documents at any stage, including but not limited to a government-issued Indonesian National ID (KTP), passport, or other acceptable proof of identity and address. Withdrawal requests above a specified threshold will trigger a mandatory KYC review. Accounts that fail to complete KYC within the timeframe specified in the verification request may have withdrawal functionality suspended until verification is satisfactorily completed.
big89 employs 256-bit SSL encryption across all connections and conducts regular security audits. Members are advised to:
big89 supports deposits and withdrawals via the following Indonesian payment channels: BCA, BRI, BNI, Mandiri, CIMB Niaga, BSI (Bank Syariah Indonesia), OVO, DANA, GoPay, ShopeePay, and LinkAja. All transactions are denominated exclusively in Indonesian Rupiah (IDR). big89 does not accept deposits in any foreign currency and does not perform any currency conversion.
big89 is committed to the prevention of money laundering and the financing of unlawful activities. big89 reserves the right to conduct enhanced due diligence on any account, to freeze funds pending investigation, and to report suspicious activity to relevant authorities in accordance with applicable international anti-money laundering standards. Members must not use big89 as a mechanism for processing funds that originate from any unlawful source.
big89 offers a range of promotional bonuses including welcome bonuses, deposit match bonuses, cashback offers, free bets, and VIP rebates. All bonuses are subject to the specific terms and conditions stated at the time of issue, as well as the general bonus rules set out in this clause. In the event of a conflict between bonus-specific terms and these general terms, the bonus-specific terms shall prevail.
Unless explicitly stated otherwise, all bonuses credited to a Member's account carry a wagering requirement before the bonus balance or any winnings derived from it may be withdrawn. The applicable wagering multiplier is stated on each individual promotion page. Wagers placed on the following game types may not contribute equally — or may not contribute at all — toward wagering requirements:
big89 employs automated and manual monitoring to detect bonus abuse. Actions that constitute bonus abuse include but are not limited to: registering multiple accounts to claim the same promotion, using low-risk betting strategies designed solely to meet wagering requirements while preserving the bonus balance, and colluding with other Members to claim referral bonuses fraudulently. big89 reserves the right to void bonuses, cancel associated winnings, and permanently close accounts found to be engaged in bonus abuse without prior notice.
big89's five-tier VIP programme — Bronze, Silver, Gold, Platinum, and Black Diamond — awards monthly rolling rebates of up to 1.2% based on verified net wagering volume. VIP status is assessed and assigned at the start of each calendar month. Downgrading of VIP tier may occur if a Member's wagering volume falls below the minimum threshold for their current tier during the assessment period. All VIP rebates are credited as withdrawable cash with no additional wagering requirement unless stated otherwise in the VIP programme terms in force at the time of crediting.
All sports bets placed on big89 are subject to the sportsbook rules displayed within the platform. big89 offers pre-match and in-play betting across a wide range of sports, including BRI Liga 1, Timnas Indonesia international fixtures, EPL, La Liga, Serie A, Bundesliga, Champions League, FIFA World Cup qualifiers, Piala AFF, MotoGP, badminton (All England, Thomas Cup, Indonesia Open), and e-sports (Mobile Legends MPL, PUBG Mobile, Free Fire). Mix parlay (accumulator) and voor bola (Asian handicap) markets are available natively within the sportsbook interface.
big89 reserves the right to void, suspend, or amend any bet in cases of obvious pricing errors, data feed failures, event cancellations, or where big89 has reasonable grounds to suspect that the integrity of the event or the bet has been compromised. Voided bets will be refunded to the Member's IDR wallet at the original stake value.
All casino games, including live dealer tables and slot titles, are provided by certified third-party studio partners including Evolution Gaming, Pragmatic Play, PG Soft, NetEnt, Microgaming, Habanero, and Spribe. Each game is governed by its own in-game rules, RTP (return-to-player) percentage, and paytable. big89 does not modify game outcomes and has no influence over third-party RNG systems. Disputes regarding individual game outcomes must be raised with big89's support team, who will escalate to the relevant studio provider if required.
Keno draws and bola tangkas (Indonesia's traditional five-card poker variant) game rounds are conducted via big89's certified gaming engine. Draw results and hand outcomes are final once confirmed by the system and displayed to the Member. Disconnection during an active round does not void the round; the result will be determined by the system and credited or deducted accordingly upon reconnection.
Once confirmed, bets cannot be cancelled by the Member except where big89's platform explicitly provides a "Cash Out" or "Bet Edit" feature for a specific market. The availability of such features is at big89's sole discretion and may be withdrawn at any time without notice.
big89 is committed to promoting responsible gambling practices. Gambling should be treated exclusively as a form of entertainment, not as a source of income. big89 provides the following responsible gaming tools to all registered Members at no cost and with no minimum waiting period:
