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.

Signs of problem 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
