Detailed Breakdown

Details on Each Bonus

Understanding the terms and conditions helps you get the most out of every bonus.

Welcome Bonus — Complete Guide

Join cv666 io and get a 100% bonus on your first deposit. Deposit ৳2,000 and your account will be topped up to ৳4,000.

The rollover requirement is 5x, meaning you need to turn over ৳20,000 using your total balance of ৳4,000. Turnovers count across Sports Betting, Live Casino, and slots — though certain games may not count at 100%, as detailed on the Terms page.

A quick tip: when completing your rollover through Sports Betting, place bets at odds of 1.5 or higher — those count at 100%.

Cashback — How to Maximize Your Returns

The cashback offer is one of the best at cv666 io, thanks to its low 3x rollover. Even when you lose, you get something back — and you can withdraw it quickly.

It's simple: say you deposited ৳5,000 last week and won ৳3,000 — your net loss is ৳2,000. 10% of that, which is ৳200, will be credited to your account every Monday morning.

Maximum weekly cashback is ৳5,000. VIP members can receive up to 15%.

Referral Program

Promotion FAQs

Answers to the most frequently asked questions about bonuses.

Yes. Once you register and make your first deposit, the bonus is credited automatically — no promo code or separate application needed. Just make sure it's your first deposit and your account is fully verified.

The bonus portion cannot be withdrawn before the rollover is completed, but your original deposited funds can be withdrawn at any time. If you cancel the bonus, your original deposit becomes fully withdrawable as normal.

Generally, you can't have two bonuses active at the same time. However, cashback and referral bonuses fall under separate categories, so you can receive both together without any issue. Contact live chat for more details.

No, cashback is fully automatic. Every Monday morning, 10% of your previous week's net losses is credited to your account. The minimum cashback amount is ৳100 — if your cashback falls below that, it rolls over to the following week.
