koi588 reserves the right to request additional verification documents at any time, including but not limited to proof of address (utility bill, bank statement), proof of payment method ownership (bank account screenshot, e-wallet verification), or additional identification documents. Failure to provide requested documents within the specified timeframe may result in account suspension or closure.
koi588 accepts deposits via the following Indonesian payment methods:
All deposits and withdrawals are processed in Indonesian Rupiah (IDR). We do not accept deposits in foreign currencies.
Minimum deposit amounts vary by payment method, typically ranging from Rp 25,000 to Rp 50,000. Maximum deposit limits are determined by your payment provider and your koi588 account level. Most deposits are processed instantly, though bank transfer processing times may vary depending on your bank's internal procedures.
You agree that all funds deposited into your koi588 account are your own legitimate funds, obtained through legal means. koi588 does not accept deposits from third parties. The name on your payment method must match the name on your koi588 account.

koi588 strives to process withdrawal requests within 15 minutes to 24 hours, with most withdrawals completed within 1 hour. Processing times may be extended during high-volume periods, bank holidays, or if additional verification is required. Withdrawals requested during Indonesian public holidays may experience delays due to banking system closures.
koi588 does not charge withdrawal fees for standard withdrawal requests. However, we reserve the right to deduct administrative fees for excessive withdrawal requests (more than 5 withdrawals per day) or withdrawals of funds that have not been wagered at least once (anti-money laundering policy).
koi588 offers various bonuses and promotions, including welcome bonuses, deposit bonuses, reload bonuses, cashback offers, and VIP rewards. All bonuses are subject to specific terms and conditions, including:
koi588 reserves the right to cancel bonuses, void bets, and confiscate winnings if we detect bonus abuse, including but not limited to: creating multiple accounts to claim bonuses multiple times, collusion with other players, irregular betting patterns designed to meet wagering requirements artificially, or any other fraudulent activity. Decisions regarding bonus abuse are final and at our sole discretion.
koi588 reserves the right to modify, suspend, or cancel any bonus or promotion at any time without prior notice. We also reserve the right to exclude specific users from promotional offers at our discretion.

Live casino games and slot games are provided by third-party game providers (Pragmatic Play, Evolution Gaming, Microgaming, NetEnt, etc.).

All game results are final and cannot be disputed except in cases of proven technical malfunction.
Lottery and togel (Indonesian numbers lottery) bets are subject to specific draw rules, payout structures, and settlement timeframes. Draw results are based on official sources and cannot be altered once published.
In the event of a technical malfunction, software error, incorrect odds display, or other system failure, koi588 reserves the right to void affected bets and refund stakes. We are not liable for losses resulting from technical malfunctions beyond our control.
The following activities are strictly prohibited on the koi588 platform and may result in account suspension, closure, and forfeiture of funds:

koi588 reserves the right to suspend or terminate your account at any time, with or without notice, if we believe you have violated these Terms & Conditions, engaged in fraudulent activity, or for any other reason at our sole discretion.
