📜 Understanding the Terms

Wagering requirements — what you need to know before using a bonus

One thing many players don't realize is that bonus funds can't be withdrawn straight away. OnlinekasinoEvery bonus at comes with a wagering requirement, meaning you need to wager a set multiple of the bonus amount before you can withdraw.

For example: if you receive a ৳1,000 BDT bonus with a 30x wagering requirement, you'll need to place ৳30,000 BDT in total wagers before withdrawing. You don't have to do it all at once — it adds up as you play.

Bonus Type Wager Validity Game Restrictions
Welcome Bonus 30x 30 Days Slots, Live
Free Spins 25x 7 Days Selected Slots
Cashback 1x 14 Days All Games
Reload Bonus 20x 14 Days Slots, Sports
Referral Bonus 10x 30 Days All Games
VIP Bonus 35x 60 Days All Games

Important: The cashback bonus has just a 1x wager requirement — meaning you only need to bet the bonus amount once before you can withdraw. It's the most straightforward bonus available.

Choose high RTP games

❓ FAQs

Frequently Asked Questions About Vouchers

Only one bonus can be active on your Onlinekasino account at a time. Once you've completed the wagering on a bonus or it expires, you can apply your next voucher. Use your vouchers one at a time, in sequence.

First, make sure the code hasn't expired and that you've met the minimum deposit requirement. If the issue persists, reach out to Onlinekasino's live chat support — they're available 24/7. Also double-check that no extra spaces were added when copying and pasting the code.

Winnings from free spins are credited to your bonus balance first. Once you meet the wagering requirement, the amount is converted to your real balance and becomes available for withdrawal. Free spin wagering at Onlinekasino is typically 25x.
