To avoid going broke when playing blackjack, it’s crucial to set a budget and stick to it, only betting what you can afford to lose. Learning and using basic blackjack strategy will help you make the best decisions and minimize the house edge. Avoid side bets, as they generally carry higher house edges, and manage your bet sizes to keep them consistent and within your limits. It’s important not to chase losses by increasing your bets, as this can lead to bigger losses. Taking breaks and knowing when to walk away—either after winning or when you're down to your last bet—will also help keep you in control. Starting with lower-stakes games can allow for longer play without significant risk, giving you a better chance to learn and stay disciplined.
