General Bonus Terms

  • A bonus may be claimed once only and cannot be used in combination with any other offer.
  • Bonus balance cannot be withdrawn directly; it converts to real money only once wagering requirements are met.
  • If wagering is not completed within the specified time limit after claiming a bonus, the bonus will be cancelled.
  • winbb reserves the right to modify, suspend, or cancel any promotion.
  • Creating multiple accounts or exploiting the system to claim bonus benefits will be treated as fraud and will result in immediate account cancellation.

06 Wagering Requirements

Wagering is a prerequisite for making bonus funds withdrawable. At winbb, wagering is calculated on the bonus amount only — not on the deposit amount.

Example Calculation
You received a ৳1,000 bonus. The wagering requirement is 15x. This means you must place ৳1,000 × 15 = ৳15,000 in bets before withdrawing.
  • Wagering counts only for games played with real money or bonus balance.
  • Certain games may contribute only partially to wagering calculations — contact the support team for details.
  • Placing bets beyond the wagering limit may result in cancellation of previous winnings.

winbb is committed to maintaining a fair and transparent gaming environment. The following activities are strictly prohibited on the platform:

  • Using bots, automated software, or any program to play games.
  • Colluding with other users to influence game outcomes.
  • Exploiting system vulnerabilities or technical errors to gain an unfair advantage.
  • Attempting to claim multiple bonuses using false identities.
  • Harassing or abusing any other user.

For any of the violations described above, winbb may immediately suspend or terminate the account and forfeit all deposited and won funds.
