Responsible Gambling Reminder
Casino terms such as RTP, house edge, volatility and wagering requirements can help explain how games work, but they do not remove the risk of losing money.
Gambling should be treated as entertainment, not as a financial strategy. Readers should set limits, avoid chasing losses and seek help if gambling becomes stressful or difficult to control.
