⏰ Weekly offer ends in:
C 666 stands out in Bangladesh's online gaming scene — not just for the games, but for a bonus and promotions culture that actually delivers. New members get a welcome bonus from day one, while returning players enjoy weekly reload bonuses, cashback, and special tournaments.
On many platforms, bonus terms are so complicated they're practically unusable. C 666 keeps it straightforward — the terms are clearly stated with no hidden rules. Browse each promotion in detail below.
Claiming a bonus at c 666 is simple — no complicated process. Just follow the steps below:
| Bonus Type | Amount | Maximum | Wager | Validity |
|---|---|---|---|---|
| Welcome Bonus | 100% | ৳5,000 | 30x | 30 Days |
| Reload Bonus | 30% | ৳2,000 | 25x | 7 Days |
| Loss Cashback | 10% | ৳3,000 | 1x | 7 Days |

Joining any online gaming platform for the first time takes a little courage — the environment is new, the games are new, and so are the rules. The c 666 Welcome Bonus is designed to make that first step easier. Deposit ৳1,000 and you'll receive an extra ৳1,000 in bonus funds, giving you ৳2,000 to start playing with. That extra balance gives you the room to explore the games, understand how they work, and figure out which ones suit you best.
The c 666 referral program is refreshingly simple. Find your referral link in your account, share it with friends or family, and once they sign up and make their first deposit, ৳500 lands in your wallet. Bring in ten people and that's ৳5,000. It's a solid way to earn regularly — especially if you're already in cricket or football groups.
This is something a lot of people overthink. Simply put — if you receive a ৳1,000 bonus with a 30x wager requirement, you'll need to place ৳30,000 in total bets before the bonus becomes withdrawable. It sounds like a lot, but it adds up naturally through regular gameplay. Just be patient and stick to consistent smaller bets rather than going big all at once.
Eid, Pohela Boishakh, the World Cup — c 666 always brings extra offers for these special occasions. Expect special cashback during Ramadan, bonus boosts during the cricket World Cup, and gift tournaments on Pohela Boishakh. Check this page regularly or turn on notifications so you never miss out.
