  • Take breaks: It's easy to lose track of time when you're engrossed in a game. Take regular breaks to avoid spending too much time and money.
  • Don't chase losses: If you're on a losing streak, don't try to win back your losses by betting more. This can lead to even bigger losses.
  • Know when to stop: If you're feeling frustrated or angry, it's time to stop playing. Gambling should be a fun activity, not a source of stress.
