Open the GK99 website or mobile app and log in with your username and password. If you don't have an account, you'll need to register first.
Go to the "Deposit" or "Wallet" option from the top menu or dashboard. You'll find the voucher code input field there.
Type your voucher code carefully in the designated field. The code may be case-sensitive, so entering it in uppercase is recommended.
Meet the minimum deposit amount required for the voucher. Each voucher has its own minimum deposit condition.
After entering the code and deposit amount, click the "Apply" button. The bonus will be credited to your account automatically.
Once the deposit is complete, your bonus balance will appear separately alongside your main balance in the wallet.

Check GK99's promotions page regularly. Special voucher codes are released ahead of major matches and festivals.
Voucher and bonus codes are now a standard feature on online betting platforms. But not all vouchers are created equal – some come with strict conditions, others don't. GK99 takes this seriously, with clearly stated voucher terms so there's no confusion.
Many users in Bangladesh start out cautiously, with small deposits. GK99's welcome voucher is perfect for this – a deposit of just ৳500 can earn a 100% bonus, giving you ৳1,000 to work with from the start. That extra balance lets you place bets on more matches right away.
Many users make simple mistakes when redeeming voucher codes that result in missing out on a bonus. These errors are easy to avoid.
GK99 distributes voucher codes through several channels. The most reliable way is to check the promotions page directly on the site. You'll also receive a welcome voucher by email after registering. Keeping app notifications on ensures you hear about seasonal codes first.
During major tournaments like the BPL, IPL, or World Cup, GK99 releases limited-time special vouchers. These codes go fast, so redeeming them promptly is important. Existing members can also receive exclusive vouchers in exchange for loyalty points.
Voucher bonuses cannot be withdrawn directly – you must first complete a specified amount of wagering. Cashback vouchers are an exception and can be withdrawn straight away. Once the wagering requirement is met, the bonus balance is added to your main balance and can be withdrawn normally.
