Bonus Terms and Conditions
These terms explain how promotions work at Great Slots Casino, from claiming an offer to completing wagering and withdrawing winnings. They apply to every bonus, free spin round and reward credited to your account with us.

How These Bonus Terms Apply
These Bonus Terms and Conditions apply to every promotion we make available to your account with us, including welcome offers, deposit matches, free spin rounds, cashback and loyalty rewards. They sit alongside our general Terms and Conditions and our Privacy Policy. Where an individual promotion carries its own rules, those rules apply in addition to the ones set out here, and the promotion-specific rules take priority if the two ever disagree.
By claiming a bonus you accept these terms. If you would prefer not to take part, you can decline the offer and play with your own funds only; declining a promotion never affects the rest of your account.
- Promotions are open only to registered account holders aged 18 or over.
- One account per person, household, device, IP address and payment method. Duplicate accounts are not eligible for promotional funds.
- A bonus is personal to you. It cannot be transferred, sold, pooled or shared with another account.
- Offers may be limited to particular player groups, deposit methods or regions, as stated in the offer text at the time it is published.
- We hold a gaming licence and carry out identity and payment checks on accounts before promotional funds or related winnings are paid out.
Bonuses are optional
A bonus is there for entertainment, not as a way to recover losses. Claim one only if you are comfortable with the wagering conditions attached to it.
Claiming an Offer and Qualifying for It
Most promotions need an action from you before they can be credited. The steps below reflect the usual route; the offer itself always sets the detail.
- Go through the offer text in the promotions area of the site so you know the wagering requirement, the qualifying games and the time limit.
- Opt in, or enter the promotional code shown, before you deposit. Codes added afterwards cannot be applied retrospectively.
- Make a qualifying deposit of at least the minimum amount shown in the cashier, using an eligible payment method.
- Wait for the bonus or free spin round to appear in your balance. If it does not arrive, contact us before placing further bets.
- Check your balance to confirm which part of it is cash and which part is bonus funds subject to wagering.
Some payment methods are excluded from promotional offers. The cashier shows which methods qualify at the moment you deposit, and a deposit made with an excluded method will not trigger a bonus even where the code has been entered correctly.
Before a withdrawal that includes promotional winnings is released, we complete our standard account checks. These confirm your identity, your age, your address and your ownership of the payment method used. Where documents are outstanding, the bonus and any winnings from it may be held until the verification is finished.
Wagering Requirements and Game Contribution
A wagering requirement is the total amount you need to stake before bonus funds, or winnings generated from them, can be converted into withdrawable cash. The requirement is expressed as a multiple in the offer text and may be applied to the bonus amount alone or to the deposit and bonus combined. Your progress towards it is shown in your account while the bonus is active.
| Term | What it means |
|---|---|
| Bonus funds | Promotional credit held separately from your cash balance until wagering is complete. |
| Wagering requirement | The total stake needed before bonus funds can become withdrawable cash. |
| Game contribution | The share of each qualifying bet that counts towards the wagering requirement. |
| Maximum bet | The highest stake per spin, round or hand allowed while a bonus is active. |
| Conversion cap | Any limit on the amount that can be converted from a bonus, as stated in the offer. |
| Bonus expiry | The period in which wagering must be completed before the bonus lapses. |
Games do not all count equally. Slots normally contribute the largest share of each bet, while table games, video poker and live dealer games contribute a smaller share or nothing at all. The contribution that applies to each game category is set out in the promotion and in the game information panel, so it is worth checking both before you start.
- Bets on games excluded from the promotion do not count towards wagering, even if they are placed with bonus funds.
- Cancelled, voided or error-affected rounds are removed from your wagering progress.
- Where a bet is partly funded by cash and partly by bonus funds, only the qualifying portion counts.
Limits That Apply While a Bonus Is Active
The following restrictions apply from the moment a bonus is credited until wagering is complete or the bonus lapses.
- Stakes must stay within the maximum bet shown in the offer and in your account.
- Bonus-buy features, gamble features and jackpot contributions may be unavailable or excluded from wagering while a bonus runs.
- Low-risk play, such as covering opposite or near-equal outcomes on table games to clear wagering with little exposure, does not count and may void the bonus.
- Withdrawal requests made before wagering is complete will remove the outstanding bonus and any winnings attached to it.
- Where your balance holds both cash and bonus funds, bets are taken in the order shown in the cashier.
Keep an eye on your stake size
Exceeding the maximum bet, even once and even accidentally, can result in the bonus and the winnings from it being withdrawn. If you are unsure of the limit on your current offer, ask us on live chat before you play.
Expiry, Cancellation and Forfeited Bonuses
Every bonus has a time limit, stated in the offer. If wagering is not completed within that period, the remaining bonus funds and any winnings tied to them are removed from your balance. Your own cash funds are never affected by a bonus lapsing.
- Wagering was not completed before the bonus expired.
- A withdrawal was requested while the bonus was still in progress.
- The maximum bet or an excluded game restriction was breached.
- The offer was claimed through duplicate accounts, inaccurate registration details or an ineligible payment method.
- Account activity shows a pattern aimed at extracting promotional value rather than playing the games.
- The account was closed, suspended, placed on time-out or self-excluded while the bonus was active.
You can cancel an active bonus at any time by contacting us by e-mail or on live chat. When a bonus is cancelled, your cash balance stays with you and the bonus funds together with any winnings generated from them are removed. Cancellation cannot be undone, and the same offer may not be available to claim again.
Changes, Fair Play and Getting Help
We may add, change or withdraw promotions at any time. Where we change these terms, the updated version applies to bonuses claimed after publication; a bonus already running continues under the terms you accepted, unless a change is needed for legal, licensing or account security reasons.
Where account records, betting patterns or payment activity indicate that an offer has been exploited, we may void the bonus and the winnings from it and restrict access to future promotions. In serious cases we may suspend the account while we look into what happened. If you disagree with a decision, raise it with us and it will be looked into under our complaints procedure.
Promotions are never a reason to spend more than you planned. You can set deposit, loss and session limits, take a time-out or self-exclude from your account at any time, and opt out of promotional messages in your communication settings. GamStop allows you to exclude yourself from all licensed online operators in Great Britain, and free confidential support is available from GambleAware, GamCare and the National Gambling Helpline.
If anything on this page is unclear, write to support@casino-greatslots.co.uk or use the live chat on the site and we will explain how the terms apply to your account.
