1. Define your bankroll
Your bankroll is what you're willing to lose. Not what you have in your bank account, not what you can afford this month, what you're willing to see go to zero without regret.
Rule of thumb: 1-2% of your monthly disposable income. If you have £2, 000 a month after rent, food and savings, £20-40 is a sensible monthly bankroll for casino play. Not £200. Not £500.
This number goes on top of the deposit-limit tools every regulated casino offers. Set the deposit limit at exactly your bankroll amount, so you can't accidentally exceed it in a hot moment.
2. Session sizing
Divide your monthly bankroll by how many sessions you plan to play. Playing twice a week? Your monthly £40 becomes 8-10 sessions of £4-5 each.
Each session gets a hard cap. When you're out for the session, you're out, no reload, no "just one more". The session cap protects you from tilt, from the "one more spin" instinct, and from correlation risk (bad sessions cluster).
3. Bet sizing per session
A session bankroll needs to survive normal variance. On slots with medium volatility, plan on 100+ spins per session, meaning your bet size should be roughly your session bankroll divided by 100. £5 session bankroll = £0.05 bets.
Higher-variance games (bonus-buy slots, high-volatility titles, live dealer with side bets) burn through bankroll faster. Halve the bet size, or accept you'll be done in 20 minutes rather than an hour.
4. Stop-loss and stop-win
Set a stop-loss (session ends when balance drops X%) and a stop-win (session ends when balance hits X% up). Common values: -100% (bust the session bankroll = done) and +50% (up 50% = withdraw and end).
The stop-win is the one most players skip. It's also the one that protects your profits from being ground back to the mean. Withdrawing while up is the emotionally hardest and financially smartest habit you can build.
Every regulated casino lets you set session time limits and win/loss reminders. Turn them on. If the casino doesn't offer them, that alone is a red flag.
5. Track what you play
A basic spreadsheet with date, casino, deposit, withdrawal, net for that session. Update after every session. Total monthly to see the real number.
Two things this reveals: (1) your actual house edge over time, which is almost always higher than you think, and (2) which casinos and games are net-positive or net-negative for you personally. Your data beats any published RTP number.
If tracking feels tedious, that's information. If watching the running total is uncomfortable, that's also information. Both are early warning signs the pattern needs to change.
Frequently asked questions
What's a good starting bankroll for a beginner?
Whatever you're 100% willing to lose. For most people that's £20-50 a month, genuinely small. Treat it like a Netflix subscription: money you spend on entertainment with no expectation of return.
Should I use bonuses to stretch my bankroll?
Bonuses can extend your play, but they come with wagering requirements that shift the math. See our bonus guide, only take offers where the terms make the expected value positive.
When should I take a break from casino play?
When you're deposit-limit-maxed and still want to top up. When you can't stop thinking about the last session. When you're chasing losses. All three are signals to step away. Every regulated casino offers cool-off periods and self-exclusion tools, use them early rather than late.
