Online casinos in the UK may offer welcome packages, free spins, and ongoing promotions. But while these offers look tempting at first glance, the practical impact depends on the T&Cs – or more specifically, in the slot bonus T&Cs.
Whether you're playing on major platforms like Prime Slots or exploring new casinos offering real money slots, it’s essential to read between the lines. This guide breaks down how to decode bonus terms and avoid common pitfalls like time-limited offers, hidden wagering requirements, and restricted game play.
Max Win Caps – The Quiet Limit You Didn’t See Coming
Some slot bonuses come with a maximum withdrawal limit, often hidden deep in the bonus T&Cs. For instance, a £100 bonus may only allow you to withdraw £50 in winnings, regardless of how much you've earned. If you're playing for real money slots expecting uncapped winnings, this can be a frustrating surprise.
What to look for:
- Phrases like “maximum win from bonus funds is capped at £50”
- Caps on winnings from free spins, often between £20–£100
- Specific references in the terms under “Withdrawal Limits” or “Winnings Cap”
Pro Tip:
Always compare the full terms across offers. A slightly smaller bonus with no max win cap might offer better value in the long run.
Wagering Requirements
Wagering requirements define how many times you must play through a bonus before it becomes withdrawable. For example, a 35x wagering requirement on a £20 bonus means you need to wager £700 before any withdrawals are allowed. Even if you hit a win, you can’t access the money until the wagering condition is met.
What to look for:
- Bonus must be wagered 30x/35x/50x before withdrawal
- Whether the requirement applies to bonus only or bonus + deposit
- Wagering requirements on free spins winnings
Pro Tip:
Some offers might sound smaller but have low wagering or even no wagering requirements – lower wagering reduces required play, but outcomes remain random.
Excluded Games – Slots That Don’t Count
Not all slot games contribute equally to wagering requirements. Some are excluded entirely; others only contribute a portion (e.g. 10% of your stake). You might spend time spinning your favourite slot, only to find out it doesn’t count towards fulfilling your bonus conditions.
What to look for:
- Lists of excluded games in the terms
- Tables showing game weighting (e.g. Slots = 100%, Table Games = 10%)
- Notes like “Jackpot games are excluded” or “NetEnt games not eligible”
Pro Tip:
Check the list before you play. Prime Slots and other online slots sites usually make this clear, but smaller casinos may bury this info.
Time Limits – Use It or Lose It
Bonuses often come with a time window in which they must be used or the wagering must be completed – typically 7 to 30 days. Unused bonuses or unmet requirements can be forfeited once the deadline expires.
What to look for:
- “Bonus expires after 7 days”
- “Free spins valid for 24 hours”
- “Wagering must be completed within 30 days”
Pro Tip:
Note the expiry date and deadlines on your phone or calendar when you claim a bonus. It’s surprisingly easy to forget you’re on a countdown.
Bet Limits – Restrictions Per Spin
Many casino promotions limit how much you can bet while using bonus funds (e.g. no more than £5 per spin). Going over the limit, even accidentally, could void your bonus and any winnings attached to it.
What to look for:
- “Maximum allowed bet is £5 while bonus is active”
- “Bonus funds must not be used with bonus buy features”
- Restrictions on autoplay or turbo mode
Pro Tip:
When using bonus money, play within limits. Some casinos may even confiscate winnings if this rule is broken.
Deposit Triggers & Bonus Codes – Don’t Miss the Fine Print
Some bonuses require a minimum deposit or a specific promo code to be activated. Failing to input the correct code or depositing below the threshold could mean you miss the offer entirely.
What to look for:
- “Minimum deposit of £10 required”
- “Use bonus code WELCOME100 when depositing”
- “Offer valid on first deposit only”
Pro Tip:
Take a moment to double-check your deposit amount and ensure any bonus codes are entered correctly before confirming payment.
Cashable vs. Non-Cashable Bonuses – Know What You Keep
What it means:
- Cashable bonuses let you withdraw the bonus amount and your winnings after wagering.
- Non-cashable bonuses (or "sticky" bonuses) allow withdrawal of winnings only, not the bonus amount.
What to look for:
- Terms stating “Bonus amount will be removed upon withdrawal”
- “Winnings only are withdrawable” vs. “Bonus and winnings can be withdrawn”
Pro Tip:
If you’re unsure, customer support can clarify whether a bonus is cashable.
