To protect themselves while gambling online, players should establish a budget and stick to it, ensuring they only wager what they can afford to lose. They can take advantage of deposit and spending limits offered by online casinos to help manage their gambling habits. Setting time limits for gaming sessions can also prevent excessive play and promote healthier gaming behavior. Players should familiarize themselves with the terms and conditions of the games and platforms they use, as well as utilize self-exclusion options if they feel their gambling is becoming problematic.
