How wagering works
'£20 bonus, 20× wagering' means you must stake £400 in total (bonus and any wins re-staked) before the balance can be withdrawn.
Only certain games count towards the requirement, and some contribute at reduced percentages. Slots typically contribute 100%; table games often 10–25%; some games are excluded entirely. Read the offer terms every time — this is where the variance comes from.
Playing +EV
Choose the lowest-house-edge game that qualifies. Blackjack often contributes at 10–20% of stake, but its edge is under 1%. Slots contribute 100% but the edge is 3–6%.
Set a stop-loss before starting. Walk away when you hit it. The whole point of +EV is that variance evens out across many offers, not one session.
The 'no wagering' variant
Some UK casinos offer 'no wagering' free spins or bonuses. These are straightforwardly good and should be prioritised — the retained value is the full face value of any winnings.
No-wagering offers usually come with a max-win cap. Read it before spinning.
Bankroll separation
Casino offers require a bigger working balance than sports offers. A £20 casino bonus with 20× wagering can swing £100 in either direction before landing on its EV.
Fund a dedicated casino balance with £100–£200 you're psychologically prepared to see go to zero (temporarily) on any single offer. This is a variance mindset, not a losing mindset.
Kelly's tips
- ✦Keep casino bankroll separate from sports bankroll — the two have very different risk profiles.
- ✦Never chase — variance evens out over dozens of offers, not one session.
- ✦Prioritise no-wagering offers where available. They're the closest thing to free money in the casino category.
Common mistakes
- ✕Playing games that don't contribute to wagering.
- ✕Continuing to wager after clearing the requirement (you're now playing at the house edge with no bonus).
- ✕Ignoring max-stake terms and voiding the bonus.
- ✕Depositing more than the offer requires and then 'having a few spins' with the surplus.
