Chasing losses: how to recognise it and stop

What chasing losses means

Chasing losses is the habit of treating a losing session as something to be fixed. Instead of accepting that the money has gone, you keep playing, deposit again or bet bigger in the hope of getting back to where you started. It can happen in a single evening, or slowly over weeks as you try to recover a bad month.

Almost everyone who gambles has felt the pull at some point. The difference between a passing thought and a problem is what you do next. If you regularly stake more than you planned because you are behind, chasing has become a pattern, and our guide to the signs of problem gambling is worth reading alongside this page.

Chasing can look like several different behaviours:

• Raising your stake after a loss so that one win would cover everything.
• Making a second or third deposit in the same session after the first budget has gone.
• Switching to a game or bet with a bigger payout because it could recover the loss faster.
• Coming back the next day specifically to win back yesterday's money.
• Using money meant for bills, savings or other people to keep going.

Why the urge to chase losses feels so strong

Losing money hurts more than winning the same amount feels good, and that imbalance pushes people to act. A loss can feel like an unfinished job, so the brain looks for the quickest way to close it. In a casino, the quickest-looking route is always one more bet.

Several thinking traps feed the urge. The gambler's fallacy tells you a win must be due after a run of losses, even though each spin, hand or roll is an independent event with no memory. Near misses on a slot can feel like progress when they are simply another losing result. And a sense of control creeps in: the feeling that a change of table, game or stake size will turn things round.

Stress, tiredness, alcohol and low mood all make chasing more likely, because they make it harder to step back and think. That link is explored further in our page on gambling and mental health.

The maths: why chasing losses makes things worse

Every casino game has a built-in house edge, the average share of each stake that the game keeps over the long run. On single-zero roulette it is 2.70%, because the wheel has 37 pockets but a straight-up win pays 35 to 1 rather than the 36 to 1 that would be fair. That edge does not care whether you are up or down. A bet placed to win back £100 costs exactly the same, on average, as a bet placed for fun.

What chasing changes is the total amount you stake. Your expected loss is simply stake multiplied by house edge, so the more you put through a game, the more you should expect to lose. The theoretical loss grows in a straight line with every extra pound wagered.

The figures above are long-run averages. Any single session can land far from them, which is exactly what keeps chasing alive: an occasional recovery feels like proof that the method works. It is not. Over enough bets, results drift towards the RTP or house edge figure, and that average is always a loss for the player.

Doubling up after a loss: the Martingale trap

The most common chasing method has a name: the Martingale system, where you double your stake after each loss so that one win recovers everything plus a small profit. On paper it looks tidy. In practice, losing runs arrive more often than people expect, and the stakes climb fast.

A red or black bet on a single-zero wheel loses 19 times in 37, because zero counts against you. The chance of losing seven in a row is (19/37) multiplied by itself seven times, which is about 0.94%, or roughly 1 in 107 attempts. Over an evening of many short sequences, that is not rare at all.

After seven losses you would need to stake £640 to chase a £5 profit, and many tables cap stakes well below that. No staking pattern changes the edge on each bet. Our comparison of Martingale and flat betting shows the same conclusion from another angle.

Warning signs that you are chasing losses

Chasing often hides behind reasonable-sounding thoughts. These questions can help you spot it early:

If several of these sound familiar, it is a good moment to pause. You do not need to wait until things feel serious before using a tool or talking to someone.

How to stop chasing losses in the moment

The urge to chase is usually strongest right after a loss and fades with time. The aim is to put a gap between the feeling and the next deposit. These steps work best if you decide on them before you start playing:

1. Stop as soon as you notice the thought "I need to win it back". Close the game rather than finishing the round or the bonus.
2. Log out completely and put your phone or laptop in another room for at least 20 minutes.
3. Write down what you lost in pounds. Seeing the figure helps you accept it as spent rather than owed.
4. Take a time-out from your account if you feel the pull to return the same day.
5. Tell someone you trust what happened, or call the National Gambling Helpline on 0808 8020 133.
6. Next time, set a deposit limit that matches the amount you are genuinely happy to lose.

UK account tools that help you stop chasing

Gambling Commission rules give every player at a licensed British site a set of tools designed to interrupt chasing. Since 31 October 2025, operators must prompt you to set a financial limit before your first deposit, and a decrease to a limit has to take effect straight away. Setting the limit when you are calm means the decision is already made before any chasing thoughts arrive.

You can also use reality checks, which pop up during play to show how long you have been gambling. Since 17 January 2025, online casino games must also display your net position and time spent during a session, so you can see in real time whether you are up or down.

Time-outs are a short, firm break. Under licence code 3.3.4, online operators must offer time-out periods (opens in a new tab) of 24 hours, one week, one month or up to six weeks.

Another rule helps too. Operators cannot let you cancel a withdrawal once requested (the ban on reverse withdrawals), so cashing out removes that money from temptation. The wider set of customer interaction rules also requires operators to watch for signs of harm, including spending patterns, and to act on them.

Bank blocks and self-exclusion for persistent chasing

If chasing keeps coming back, stronger barriers help. A bank gambling block stops your card paying gambling merchants. The Gambling Commission lists banks offering blocks, including Barclays, HSBC, Lloyds, Halifax, Bank of Scotland, Monzo, NatWest, RBS, Santander and Starling. Several build in a delay before a block can be switched off: Lloyds and Starling both use 48 hours, and HSBC keeps declining gambling payments for 3 days after you turn its restriction off. See our page on bank gambling blocks for how each one works.

GAMSTOP is the free national self-exclusion scheme for online gambling in Great Britain. You choose a period between 6 months and 5 years, and it cannot be cancelled early. All licensed online operators have had to take part since 31 March 2020. For more on the options, read how to self-exclude.

What to do after a big loss

A large loss can bring panic, shame and a strong urge to fix it immediately. The kindest thing you can do is slow down. Avoid making any money decision that night, and do not try to borrow to cover the gap.

If the loss affects bills, rent or debts, free advice is available. StepChange offers free debt advice (opens in a new tab) and our page on gambling debt help covers the next steps. Remember that credit cards cannot be used to gamble in Great Britain since 14 April 2020, so if you are tempted to use borrowed money in other ways, treat that as a clear sign to seek support.

If you feel overwhelmed or unsafe after a loss, talk to someone now. The National Gambling Helpline, run by GamCare, is free on 0808 8020 133, 24 hours a day. In an emergency, call 999.

Getting support with chasing losses

You do not have to be in crisis to ask for help. GamCare runs the National Gambling Helpline (opens in a new tab) by phone, live chat and WhatsApp, and can talk through what has been happening and what might help. NHS gambling clinics in England accept self-referrals, and Gamblers Anonymous holds peer-support meetings. Our overview of gambling support in the UK lists the options, and the NHS treatment guide explains what treatment involves.

If someone close to you is chasing losses, they may not see it yet. Our guide to talking to someone about gambling has practical ways to start that conversation, and the safer gambling hub brings every tool and guide together in one place.
