This is not an exhaustive list but the more these signs seem to fit the person, the more likely it is they need to review or seek help for their gambling behaviour:

• Preoccupied with gambling and unable to stop
• Spending increasing amounts of time playing on Internet gambling sites or visiting external gambling venues with increasing frequency
• Reliving past gambling experiences, planning the next gambling venture, continually talking about new ways to get money
• Bragging about gambling, exaggerating wins and minimizing losses
• Becoming withdrawn, restless or irritable when attempting to reduce or stop gambling.
• Losing interest in other pastimes and hobbies, refusing invitations to attend social events with friends and colleagues
• Increasingly spending available free time on gambling activities.
• Gambling alone more and more, especially for long periods
• Gambling with increasing amounts of money
• Gambling to win back money that has been lost
• Borrowing money for gambling or in order to pay off gambling debts
• That they are finding that after losing money gambling, they continue to gamble in order to get back those losses (“chasing”)
• Lying to others in order to conceal the extent of gambling
• Unpaid bills and debts
• Unexplained absences
• Losing work time because of gambling or jeopardizing job by gambling
• Doing something illegal to get money for gambling
• Ability to control their gambling is lost, and repeated efforts to reduce or stop gambling are unsuccessful
