Responsible Gambling
Betting should be entertainment, never a way to make money or recover losses. Only stake what you can afford to lose and set limits before you start.
Warning signs include chasing losses, betting more than planned and borrowing to bet.
Help is available. In the Netherlands: Loket Kansspel (loketkansspel.nl) and Cruks. Internationally: GamCare and Gambling Therapy. You must be 18+ to gamble.
