Gambling should be entertainment you have budgeted for. When it becomes a way to chase losses, fill time or manage stress, it has stopped being entertainment and the tools below exist for exactly that moment.
Spending more than you planned. Chasing losses with bigger stakes. Gambling to escape a bad mood. Hiding it from people close to you. Borrowing to fund it. Feeling restless when you try to stop. Any one of these is worth taking seriously; several together is a clear signal.
Every operator listed on this site offers deposit limits, session reminders, cooling-off periods and self-exclusion. Deposit limits are the single most effective one because they act before you play rather than after. Set them when you open the account, while the decision is easy.
Blocking software such as Gamban or GamBlock covers every site at once rather than one at a time, which is what most people actually need.
