Slot bankroll guide
A budget is a number of spins waiting to be chosen. Decide the number and the rest follows.

Key takeaways
- Budget ÷ spins = stake.
- Aim for 200+ spins on high volatility slots.
- Set a loss limit and a time limit.
- Withdraw wins.
The basic sum
| Budget | 100 spins | 200 spins | 400 spins |
|---|---|---|---|
| £10 | £0.1 | £0.05 | £0.03 |
| £20 | £0.2 | £0.1 | £0.05 |
| £50 | £0.5 | £0.25 | £0.12 |
| £100 | £1 | £0.5 | £0.25 |
Any combination: spin calculator.
Volatility changes the target
| Volatility | Sensible minimum | Why |
|---|---|---|
| Low | 100 | The game shows itself quickly |
| Medium | 150 to 200 | Features are less frequent |
| High | 200 to 400 | The feature carries the return |
Two limits
A loss limit: the budget, set as a deposit limit at the casino. A time limit: at the UK minimum speed, 200 spins is about eight minutes of continuous play, so decide how long you want to be there.
What to do with a win
Decide in advance. One rule: if the balance doubles, withdraw the original budget and play on with the rest, or stop.
Never
- Raise the stake to recover losses.
- Deposit again in the same session.
- Use money meant for anything else.

A worked session
| Decision | Choice | Reason |
|---|---|---|
| Target spins | 200 | Room for the feature to appear |
| Stake | 10p | £20 ÷ 200 |
| Minimum time | 8 min 20 s | 200 × 2.5 seconds |
| Average long-run cost | About £0.70 at 96.5% | On the £20 staked once |
| Stop if | Balance reaches £0, or 20 minutes pass | Loss and time limits |
In practice wins are re-staked, so the session lasts longer and stakes more than £20 in total. The plan sets the floor.
Splitting a monthly budget
If you allow yourself £40 a month, four £10 sessions give four evenings; one £40 session gives one. Smaller sessions also make it easier to stop on the day.
Bonuses and bankroll
Wager-free spins add to a session without adding to its cost. A wagered bonus is different: it commits you to a set amount of staking by a deadline, so plan it as part of the budget, not on top.
