This Bonus Policy sets out the terms that apply to all promotions and bonus offers available at Winner Island (winnerislandbet.nl). By claiming any bonus or free spins, you confirm that you have read, understood, and agreed to the conditions below. These terms apply alongside Winner Island's general Terms and Conditions and, in the event of any conflict, these bonus-specific terms shall prevail in relation to promotional matters.
New players at Winner Island are eligible for a casino welcome package spread across three qualifying deposits, totalling up to €1,000 in bonus funds plus 100 free spins on Big Bass Bonanza. The full breakdown is as follows:
| Deposit | Match Percentage | Maximum Bonus | Free Spins |
|---|---|---|---|
| 1st Deposit | 100% | €100 | 10 spins per day for 10 days on Big Bass Bonanza |
| 2nd Deposit | 50% | €200 | — |
| 3rd Deposit | 25% | €700 | — |
| Total | — | €1,000 | 100 free spins |
The minimum qualifying deposit at each tier is €20 (or currency equivalent). Deposits below this threshold will not trigger the corresponding bonus.
Not all games contribute equally towards wagering requirements. The following contribution rates apply:
| Game Type | Contribution Towards Wagering |
|---|---|
| Slots | 100% |
| Live Casino (roulette, blackjack, baccarat) | 10% |
| Standard Table Games | 5% |
| Progressive Jackpot Titles | 0% (no contribution) |
Winner Island recommends that players who hold an active casino bonus take particular care when choosing to play live casino games, as the reduced contribution rate of 10% will significantly extend the time required to complete wagering requirements. Playing jackpot titles whilst a bonus is active will not contribute to clearing the requirement at all.
Whilst any casino bonus is active on your account, the maximum permitted bet or spin stake is €5 per spin or per bet. Placing bets in excess of this limit whilst a bonus is live may result in the forfeiture of the bonus and any associated winnings.
Each daily batch of free spins may carry an individual expiry period. Any free spins not used within their validity window will expire and be removed from your account. Winnings from expired free spins will not be retained.
Winner Island offers a separate sports welcome bonus of a 100% match up to €100 on your first qualifying sportsbook deposit. This offer is entirely independent of the casino welcome package, and eligible players may claim both promotions provided all relevant conditions are met.
The minimum qualifying deposit to activate the sports welcome bonus is €20 (or currency equivalent).
Wagering requirements and qualifying bet conditions for the sports welcome bonus will be communicated at the point of claiming. Players should review these conditions in full before accepting the offer. Any winnings from sportsbook bonus funds are subject to the wagering requirements stated at the time of the promotion.
In addition to the welcome package, Winner Island runs a range of recurring promotions for both casino and sports players. The following promotions are currently available, and each is governed by its own specific terms which will be displayed at the time of the offer:
| Promotion | Summary |
|---|---|
| Mystery Treasure Drops | Play today for a mystery reward worth up to €100, credited to your account the following day. Specific eligibility, wagering, and game restrictions apply per drop. |
| Kash Drops | A prize pool of €10,000,000 in cash rewards distributed through eligible slot reels. Qualifying games and distribution mechanics are detailed within the promotion. |
| Sports Weekly Reload | A 75% deposit match up to €500 on your weekly sportsbook deposit. Available to eligible sports players on a recurring weekly basis. |
| MultiBoost | Stack accumulator legs to increase your potential return on winning selections. Boosted value grows with each additional leg added to your bet. |
| Matchday Boost | Enhanced odds on selected standout football fixtures throughout the week. Available on qualifying matchdays as specified at the time of the promotion. |
| Telegram Treasures | Exclusive offers distributed to members of the Winner Island Telegram channel. Availability and terms vary per offer issued via that channel. |
All ongoing promotions are subject to change or withdrawal at Winner Island's discretion. Where a promotion carries bonus funds or wagering requirements, the ×40 standard wagering multiplier and €5 maximum bet restriction shall apply unless the individual promotion's terms state otherwise. Players are advised to read the full terms of each promotion before participating.
All deposits made at winnerislandbet.nl are subject to a 1× (one times) wagering requirement before a withdrawal may be requested. This applies regardless of whether a bonus has been claimed. This condition exists as a standard anti-money-laundering measure and does not affect the bonus wagering requirements described elsewhere in this policy.
The following withdrawal limits apply to all accounts at Winner Island, including winnings derived from bonus play:
| Limit Type | Amount |
|---|---|
| Minimum Withdrawal | €/$100 |
| Daily Withdrawal Limit | €/$4,000 |
| Weekly Withdrawal Limit | €/$16,000 |
| Monthly Withdrawal Limit | €/$50,000 |
| Progressive Jackpot Wins | Paid in full — outside and above the monthly withdrawal cap |
Progressive jackpot wins are treated separately and are not subject to the standard monthly withdrawal limit of €50,000. Such wins are paid out in full. All other winnings, including those generated through bonus play, are subject to the withdrawal limits set out above. Processing of approved withdrawals takes up to 5 banking days. Winner Island does not charge transaction fees on withdrawals; however, your payment provider may apply their own charges, which are outside Winner Island's control.
Winnings generated from free spins (as part of the welcome package or any other promotion) are subject to a maximum withdrawal cap of €1,000 unless the specific promotion states a different limit. Winnings in excess of this cap will be removed from your account upon completion of wagering requirements.
Bonuses at Winner Island are available in the following supported currencies: EUR (Euro), USD (US Dollar), and Bitcoin. Where bonus amounts are stated in EUR, the equivalent value in USD or Bitcoin will be applied at the prevailing exchange rate at the time the bonus is credited. Bonus values stated in EUR are illustrative of the maximum benefit available; actual values in other currencies may differ slightly due to exchange rate fluctuations.
Winner Island operates under a licence issued by the Union of the Comoros. As part of our regulatory obligations, all players are required to complete identity verification (KYC) before withdrawals — including those of bonus winnings — can be processed. Failure to provide satisfactory verification documentation within a reasonable period may result in the suspension of your account and the forfeiture of any pending bonus balances.
KYC requirements include, but may not be limited to:
Bonuses will not be paid to players who cannot be verified to the satisfaction of Winner Island's compliance procedures. Where a bonus has been credited prior to verification and the player subsequently fails KYC, the bonus and any winnings derived from it will be voided.
Winner Island is committed to promoting safe and responsible gambling. We encourage all players to consider their gambling activity carefully and to make use of the responsible gambling tools available on winnerislandbet.nl.
Winner Island employs monitoring systems to detect bonus abuse, collusion, and fraudulent activity. The following behaviours are considered a breach of this Bonus Policy:
Where bonus abuse or fraudulent activity is identified, Winner Island reserves the right to void the relevant bonus and all associated winnings, suspend or permanently close the account, and recover any funds that have been withdrawn as a result of such activity. Winner Island's decision in these matters is final.
Winner Island reserves the right to amend this Bonus Policy at any time. Where changes are material, reasonable notice will be provided via the winnerislandbet.nl website or by email to the address registered on your account. Continued participation in promotions following the publication of any amended terms constitutes your acceptance of those changes.
If you have any questions about this Bonus Policy or any active promotion, the Winner Island support team is available as follows:
Our team will endeavour to respond to all email enquiries promptly. For urgent matters relating to an active bonus or withdrawal, live chat is the recommended contact method.
