Before placing bets on b650mk, it helps to understand a few basic rules. They'll keep you from running into confusion and make your overall experience much smoother.
Void Bet: If a match is cancelled or does not finish within the scheduled time, the bet is voided and your full stake is refunded.
Pre-match betting is available right up until a match kicks off. Live betting can be placed at any point during the match, though odds change in real time.
An accumulator bet combines multiple matches into a single wager. If any one match loses, the entire bet is lost — but a winning accumulator pays out at much higher returns.
With b650mk's cash out feature, you can take partial or full winnings before a match ends. It's a great way to manage your risk.
Minimum and maximum bet limits vary by market. Open the bet slip on the odds page and the limits will be displayed automatically.
B650mk offers attractive bonuses for both new and existing players. Just make sure you read and understand the terms before claiming any bonus.
Special bonus on your first deposit. Available to new members only. Wagering requirement: 8x.
Get cashback based on your net losses each week. VIP members receive a higher cashback rate.
Reload bonuses are available on every deposit — offered on select days or during special events.
Withdrawing before completing the bonus wagering requirement will cancel your bonus balance. However, your original deposit amount can still be withdrawn.
B650mk takes the security of your account and personal information seriously. We use SSL encryption and advanced security technology — but you should also take a few precautions on your end.
