What Are Sticky and Non-Sticky Bonuses?
Welcome bonuses at online casinos generally fall into two categories: sticky and non-sticky. A sticky bonus remains attached to your account until wagering requirements are met, meaning you cannot withdraw the bonus amount separately – only winnings derived from it after playthrough. A non-sticky bonus, by contrast, lets you withdraw your original deposit immediately, while the bonus funds are used purely for wagering; any winnings above the initial deposit are subject to rules. This distinction dramatically affects how you manage your bankroll. At Spin-kings, the welcome offer follows a clear structure that you should understand before depositing.

The Mechanics of a Sticky Bonus at Spin-kings
A sticky bonus at Spin-kings casino ties both your deposit and the bonus funds together. For example, if you deposit €100 and receive a 100% sticky match, you play with €200. To withdraw any profit, you must meet the wagering requirement (typically 35× the deposit plus bonus). The casino locks the bonus amount – you cannot cash it out even after wagering. Key details: the maximum bonus amount is €200, and the wagering period is 21 days. Only slots contribute 100%, while table games contribute 10%. The highest RTP slots available (96.5% or more) help you clear the requirements faster. You must also complete KYC (upload a government ID and a recent utility bill) before any withdrawal, a process that usually takes 24–48 hours after submission.
How Non-Sticky Bonuses Work and Their Advantages
Non-sticky bonuses, sometimes called “clearable” or “phantom” bonuses, separate your deposit from the bonus funds. At Spin-kings bonus offerings, a non-sticky variant might work as follows: you deposit €100 and get €100 in bonus funds, but you can withdraw your original €100 at any time. The bonus is used only for play; if you lose the bonus, you lose nothing beyond your own deposit. Wagering requirements (often 40× the bonus) apply only to the bonus, not the deposit. This reduces risk because you preserve your capital. Payment methods like Skrill, Neteller, Visa, and Paysafecard are accepted, each with deposit limits (e.g., €10 minimum, €2,500 maximum). One drawback: the maximum cashout from non-sticky winnings is usually capped at 10× the bonus, whereas sticky bonuses often have no cap – a trade-off you must weigh.
Step-by-Step: Claiming Your Welcome Bonus
- Navigate to the registration page and create an account. Enter the Spin-kings promo code during the sign-up step (if required) to unlock the welcome offer.
- Choose your preferred deposit method. Options include Visa, Mastercard, Skrill, Neteller, and Paysafecard. The minimum deposit is €10.
- Select the sticky or non-sticky variant if the promotion offers a choice. Check the offer terms – the Spin-kings no deposit bonus (if available) is separate, but for a deposit bonus you must add funds.
- Complete the deposit. The bonus is credited automatically or after contacting support. You will also receive Spin-kings free spins (usually 50 on a featured slot like Book of Dead).
- Begin playing. Focus on games with high contribution percentages. Use the “wagering tracker” in your account to monitor progress.
- After meeting the requirements, request a withdrawal. Ensure your KYC documents are approved first.
Wagering Requirements and Practical Tips
Understanding the math behind wagering is crucial. A sticky bonus of €100 + €100 requires (€200 × 35 = €7,000) in turnover. At an average RTP of 96%, you statistically lose about €280 during wagering – which may exceed the bonus value. For a non-sticky bonus, the turnover is lower: €100 × 40 = €4,000, with expected loss around €160. Always check the game restrictions: slots from providers like NetEnt and Play’n GO usually count fully, while live dealer games count only 5–10%. The typical time limit for both bonuses is 21 days, but non-sticky offers sometimes allow up to 30 days. If you prefer lower risk, choose the non-sticky option; if you aim for larger potential wins, the sticky bonus may be better despite the higher wagering.

Once you decide, always read the full bonus terms. Pay attention to excluded games, maximum bet limits (often €5 per spin), and country restrictions. The choice between sticky and non-sticky ultimately comes down to your playing style: high rollers may lean sticky for uncapped potential, while cautious players prefer non-sticky for capital protection. Use the tips above to make an informed decision at spin-kings. After you claim your bonus, track your progress daily and avoid chasing losses – the house edge ensures long-term profitability for the casino, but short-term you can walk away with a win if you manage your bankroll well.
