A set of fundamental rules applies to all bets placed on BB4. These rules are in effect across all Sports Betting and casino games.
Once a bet is confirmed, it cannot be changed or cancelled — unless the Cash Out feature is available. For in-play betting, if a bet is placed at the moment odds change, the new odds will apply and will be shown to you before confirmation.
If a match is cancelled or ends before its scheduled conclusion, bets will be settled in accordance with BB4's settlement policy — generally, if 50% or more of the match has been completed, results will follow DLS or official outcomes; otherwise, bets will be voided.
BB4 reserves the right to suspend, review, or void any bet where unusual or suspicious betting patterns are detected. If there is clear evidence of match-fixing or unfair advantage, the account involved will be permanently closed.
All casino games on BB4 are RNG (Random Number Generator) certified. RTP (Return to Player) information for each game is available in the game lobby. No external control influences game outcomes — all results are entirely random.
If a technical error or disconnection occurs during gameplay, the outcome will be determined based on BB4's server logs. If a game is interrupted mid-session, contacting support will result in a resolution within 24 hours.
Tips: Before placing a bet, you can check the full rules for any market in BB4's Help section or by asking support directly. Parlay bet rules in particular can differ from standard bets.
