Responsible Gambling
Gambling should be entertaining, not a way to make money. Only bet what you can afford to lose, and never chase your losses. Set limits on time and money spent gambling.
- Betting more than you can afford to lose
- Chasing losses with bigger bets
- Lying to others about gambling habits
- Gambling interfering with work or relationships
