Account & Registration
Creating a koi138 account takes under three minutes. Visit koi138.cam, click the registration button, and fill in your full legal name, date of birth, email address, Indonesian mobile number, and a secure password. You must be at least 21 years old and confirm that you agree to the koi138 Terms & Conditions before your account is activated.
koi138 requires a valid government-issued photo ID — typically your Indonesian KTP (national identity card) or passport. You will also need to provide a selfie holding your ID and, for withdrawals above a certain threshold, proof of your payment method (for example, a screenshot of your BCA or Mandiri mobile banking account showing your name and account number). KYC verification is usually completed within 24 hours on business days.
No. koi138 strictly enforces a one-account-per-player policy. Each player is permitted exactly one registered account. Duplicate accounts are detected through device fingerprinting, IP monitoring, and payment method checks. Any account identified as a duplicate will be permanently closed and any associated bonus funds will be voided. If you have trouble accessing your existing account, contact support rather than registering again.
Click the "Forgot Password" link on the koi138 login page and enter the email address registered to your account. You will receive a password-reset link within a few minutes — check your spam or junk folder if it does not appear in your inbox. If you no longer have access to your registered email address, contact koi138 live chat support for assisted account recovery with identity verification.
You can request permanent account closure by contacting koi138 support via live chat or by emailing [email protected]. Before closure, any remaining balance will be withdrawn to your verified payment method. If you are closing your account due to problem gambling concerns, we strongly encourage you to use the self-exclusion tool in your account settings instead, which includes a cooling-off period and follow-up support resources.
Deposits & Withdrawals
BCA bank transfers to koi138 are typically credited within 1–5 minutes during normal banking hours (Monday to Friday, 06:00–21:00 WIB). Transfers made outside these hours or during peak periods such as Idul Fitri may take slightly longer. If your deposit has not been credited after 30 minutes, contact koi138 live chat support with your transfer receipt for a manual check.
koi138 accepts deposits from all major Indonesian banks including BCA, BRI, BNI, Mandiri, CIMB Niaga, OCBC NISP, BSI (Bank Syariah Indonesia), and Bank Permata.

Visa and Mastercard are also accepted for international card payments.
The minimum deposit on koi138 is Rp 10.000 for e-wallet payments (OVO, DANA, GoPay, ShopeePay, LinkAja) and Rp 25.000 for bank transfer deposits via BCA, BRI, BNI, or Mandiri. There is no maximum deposit limit imposed by koi138, though your individual bank may apply its own daily transfer limits. For large deposits, we recommend completing your KYC first to avoid processing delays.
The minimum withdrawal to a Mandiri bank account on koi138 is Rp 50.000. Withdrawals to other major banks — BCA, BRI, BNI, CIMB Niaga — share the same minimum threshold. E-wallet withdrawals via OVO, DANA, or GoPay have a minimum of Rp 20.000. All withdrawals require a verified account (completed KYC). koi138 does not charge a processing fee on withdrawals; however, your bank may apply its own inter-bank transfer fee.
koi138 processes the vast majority of withdrawal requests within 5–15 minutes for verified accounts during standard operating hours (WIB). E-wallet withdrawals to OVO, DANA, GoPay, ShopeePay, and LinkAja are typically the fastest. Bank transfer withdrawals to BCA, BRI, BNI, and Mandiri may take up to 1 business hour. Withdrawals submitted outside standard banking hours may be processed the following morning. First-time withdrawals may take slightly longer due to additional security checks.
koi138 does not charge any platform-side fees on deposits or withdrawals. All transaction processing within the koi138 system is free. However, your individual bank or e-wallet provider may apply their own inter-bank transfer or service fees — for example, BRI and BNI charge a standard inter-bank transfer fee of Rp 6.500 per transaction. We recommend checking your bank's current fee schedule to understand any charges applied at the banking level.
Games & Gameplay
Yes. You can fund your koi138 account using OVO and then use that balance to play togel (Indonesia's traditional numbers lottery) on the platform. koi138 offers multiple togel markets including 4D, 3D, and 2D draw formats with draws from major international pools. Simply deposit via OVO in the koi138 cashier, and your balance is instantly available across all game types including togel, slots, and live casino.
koi138 covers an extensive range of football betting markets including BRI Liga 1 (Indonesian top-flight football with clubs such as Persija Jakarta, Persib Bandung, and Bali United), the English Premier League, La Liga, Serie A, Bundesliga, UEFA Champions League, and FIFA World Cup qualifiers. Market types include 1X2 match result, Asian Handicap, Over/Under goals, correct score, both teams to score, first goalscorer, and mix parlay (accumulator) bets. Timnas Indonesia (Garuda) international fixtures are also covered.
Mix parlay (accumulator betting) on koi138 allows you to combine multiple match selections into a single bet slip. All selections must win for the bet to pay out, but in return the odds of each selection are multiplied together, producing significantly higher potential returns than single-match bets. koi138 allows a minimum of 3 selections per mix parlay slip and supports Asian Handicap, 1X2, and Over/Under markets within the same accumulator. Minimum stake for mix parlay bets is Rp 1.000.
koi138 features a wide library of slot gacor (high-payout slot games) from leading providers including Pragmatic Play, NetEnt, Microgaming, and Pocket Games Soft. Return-to-player (RTP) rates vary by title — most games on koi138 carry an RTP between 94% and 97%, with individual game RTP figures displayed on the game information page before you start playing. All slot games on koi138 use certified random number generator (RNG) technology audited by independent testing laboratories.

Matches are streamed live with minimal latency, and odds are updated in real time. Minimum bet per match is Rp 5.000. All sabung ayam events are available to verified accounts only.

Bonuses & Promotions
koi138 offers a welcome bonus for new players on their first deposit. The bonus percentage and maximum amount are displayed on the koi138 promotions page and are subject to change. To claim the welcome bonus, ensure you opt in during the deposit process — the bonus is not automatically applied. All welcome bonus funds are subject to wagering requirements before withdrawal. Full bonus terms, including eligible games and minimum odds requirements, are listed on the individual promotion detail page.
Wagering requirements on koi138 specify how many times you must wager the bonus amount (or in some cases, bonus plus deposit) before the resulting balance becomes withdrawable. For example, a bonus of Rp 100.000 with a 10x wagering requirement means you must place bets totaling Rp 1.000.000 before withdrawing. Wagering requirements vary by promotion type. Bets placed on certain game categories — particularly low-margin live casino tables — may contribute at a reduced percentage. Always read the specific terms on each promotion.
Yes. koi138 offers weekly cashback and rebate promotions across multiple product categories including sports betting, slots, and live casino. Cashback is typically calculated as a percentage of your net losses during the promotion period and is credited to your account automatically at the start of the following week. Rebate promotions for slot gacor games return a percentage of total wagers regardless of win or loss outcome. Specific cashback rates and caps are listed on the koi138 promotions page.
koi138 operates a multi-tier VIP loyalty program that rewards consistent players with escalating benefits. Higher VIP tiers unlock benefits such as increased withdrawal limits, priority processing, dedicated account managers, exclusive bonus offers, and invitations to special events. VIP tier progression is based on cumulative wagering volume over a rolling period. Full details of the koi138 VIP program tiers, thresholds, and benefits are available within your account dashboard under the Loyalty section.
Safety & Responsible Gaming

All games use certified RNG technology to ensure provably fair outcomes. Financial transactions are processed through established Indonesian payment networks including BCA, BRI, BNI, Mandiri, and major e-wallet providers. koi138 does not share your personal data with third parties except as required for payment processing, KYC verification, and regulatory compliance.
koi138 employs multiple layers of account security including TLS 1.2+ encrypted connections, two-factor authentication (2FA), login anomaly detection, and device fingerprinting.

koi138 strictly enforces a minimum age requirement of 21 years old for all players. This applies to all users accessing the platform from Indonesia and is non-negotiable. Age is verified as part of the KYC process using government-issued identification. Any account found to belong to a player under 21 will be immediately closed and any deposited funds will be returned. If you are a parent or guardian concerned about a minor accessing the platform, please contact [email protected] immediately.
All responsible gaming tools — including daily, weekly, and monthly deposit limits, loss limits, session time limits, reality check reminders, time-out periods, and self-exclusion — are available directly within your koi138 account settings under the Responsible Gaming tab. No support contact is required to activate these controls. Limit reductions take effect immediately; limit increases have a mandatory 24-hour cooling-off period. Self-exclusion is available for periods of 6 months, 1 year, 5 years, or permanently, and cannot be reversed once activated.
