How does chasing losses happen and why is it considered a warning sign of problem gambling?

You're probably asking because you — or someone you know — has noticed a session going longer than intended, with each new bet feeling less like entertainment and more like a mission to get back to even. That feeling has a name, and understanding it clearly is genuinely useful.

What chasing losses actually means

Chasing losses is the compulsive need to gamble more in order to "win back" lost money — a cycle driven by the false belief that one more bet will fix past mistakes or recover financial stability. It sounds logical in the moment, but it isn't: each spin or hand is an independent event with the same house edge as the last one. The math doesn't care what you lost an hour ago.

The reason it feels so compelling is neurological, not a character flaw. An Oxford University study found that people who chase losses experience increased activity in brain areas linked to the expectation of a reward, while people who cut their losses show increased activity in areas associated with anxiety and conflict monitoring — it's brain chemistry, not a personal shortcoming. Meanwhile, players get tunnel vision, becoming hyper-focused on imagining what it will feel like to win without thinking about how much worse things will be if they lose.

There's also a cognitive distortion layer on top of that. Gambling-related cognitive biases cause people to overestimate personal skill and the probability of winning, leading to further attempts to recoup losses through continued gambling. That's why someone can know intellectually that the odds haven't changed and still feel certain that a win is "due."

Why it's a clinical warning sign, not just bad luck

Chasing losses is a key criterion for gambling disorder in the most recent edition of the Diagnostic and Statistical Manual of Mental Disorders. It's not simply losing more than planned — it's the shift in motivation from playing for enjoyment to playing to escape or reverse a financial reality. Chasing is considered one of the key risk factors in the transition from recreational to disordered gambling.

The behaviour stems from the false belief that one more bet will fix past mistakes or recover financial stability — yet this mindset typically deepens losses and emotional distress. From there, the consequences can compound quickly: unexplained financial problems appear, debt mounts, people borrow from friends or family, and bills go unpaid, creating a ripple effect of financial instability.

Note that Ontario's regulated online casino operators are explicitly prohibited from encouraging this behaviour. The AGCO's Registrar's Standards require that games must not encourage players to chase their losses, and advertising must not encourage play as a means of recovering past gambling or other financial losses. Operators are also required to actively monitor for it: identifying players who exhibit signs of at-risk behaviour is a key part of an operator's responsibility, and chasing losses is explicitly listed as a player behaviour indicator that operators must monitor as part of their risk-profiling approach.

What you can do about it in Ontario's regulated market

The most practical tool for breaking the cycle before it starts is limit-setting. Regulated internet gaming sites in Ontario must provide limit-setting features to help players manage time and money spent gambling; you can set limits at any time, and if you want to relax or remove one, it cannot take effect until after a cooling-off period of at least 24 hours. That enforced pause is specifically designed to interrupt the impulse to chase.

If you're 19+ and want a stronger break, iGaming Ontario has launched BetGuard, a centralized self-exclusion program that allows players to register to take a break from all regulated online gambling websites in Ontario in a single request. You can find it at betguard.ca. And if you're concerned that chasing has already become a pattern rather than a one-off bad session, ConnexOntario (1-866-531-2600) connects you with free, confidential support across the province — it's a genuinely good resource and worth a call.
