What Is a Sticky Bonus? The Casino Rule That Can Trap Your Deposit

A sticky casino bonus is a promotion in which the bonus remains attached to your account while its conditions are active, often restricting withdrawal of both the bonus and your deposited cash until wagering is completed or the promotion is cancelled.

That is the practical meaning behind the word “sticky”: the bonus does not simply sit beside your money as a separate gift. It can change how the whole promotional balance behaves.

This matters because a casino might advertise “Deposit €100, get €100” and display €200 in your account. Seeing €200 does not necessarily mean you have €200 of immediately withdrawable cash. Under a sticky bonus, some or all of that balance can remain subject to bonus rules.

What does sticky bonus mean?

In simple terms, a sticky bonus is a casino bonus that is tied to the player's account or deposited funds until its conditions are resolved.

A typical sequence looks like this:

1. You deposit real money.
2. The casino adds bonus funds.
3. The promotion becomes active.
4. Your balance is subject to the bonus terms.
5. You complete the wagering requirement, cancel the bonus, or otherwise reach the end of the promotion.
6. Only then does the casino determine what portion of the remaining balance is withdrawable under those terms.

The exact implementation varies by casino. Some operators show one combined balance. Others display “cash” and “bonus” wallets separately while still applying withdrawal restrictions to the account.

Because the terminology is not perfectly standardized across the industry, the actual bonus terms always take priority over the label.

A simple €100 sticky bonus example

Suppose a casino advertises:

• 100% deposit match;
• maximum bonus of €100;
• 35x wagering on the bonus.

You deposit €100 and receive another €100 as bonus funds. Your displayed total is €200.

The wagering requirement is based on the €100 bonus:

€100 × 35 = €3,500

That means €3,500 of qualifying bets must be placed to satisfy the wagering requirement.

If the bonus is sticky, your original €100 may also be unavailable for normal withdrawal while the promotion remains active. You cannot necessarily deposit €100, claim another €100, play briefly, and then withdraw your original €100 while leaving the bonus behind.

If you request a withdrawal before completing the requirement, the casino may cancel the promotion. What happens to the bonus and any associated winnings depends on the terms.

That is why sticky bonuses can surprise players who focus only on the amount credited.

Does a sticky bonus lock your deposit?

It can.

This is the feature that makes sticky bonuses materially different from many non-sticky or cash-first promotions.

When you claim a sticky bonus, your deposited cash can become connected to the active bonus conditions for withdrawal purposes. The money has not necessarily ceased to be your cash, but your ability to withdraw it can be restricted while the promotion is active.

A casino's terms should explain what happens if you try to withdraw early. Common possibilities include:

• the bonus is cancelled;
• remaining bonus funds are removed;
• bonus-derived winnings are removed;
• the withdrawal is blocked until the bonus is cancelled;
• the player is asked to confirm forfeiture of the promotion.

There is no single rule that every casino follows.

Sticky does not mean the bonus is withdrawable

Another source of confusion is the bonus amount itself.

A sticky bonus may be non-cashable, meaning the original bonus credit is used to play but is removed before a withdrawal. In that structure, the bonus acts more like temporary playing funds than cash added permanently to the account.

For example, imagine you deposit €100, receive a €100 sticky non-cashable bonus, complete the wagering requirement, and finish with €260. Depending on the terms, the original €100 bonus could be deducted, leaving €160 eligible for withdrawal.

Other promotions may convert bonus funds into cash after wagering.

These are different mechanics. “Sticky” describes how the bonus remains attached to the account; “cashable” or “non-cashable” describes whether the bonus credit itself can ultimately become withdrawable.

Sticky bonus vs non-sticky bonus

The easiest comparison is to look at what happens to your own money first.

With a sticky bonus, the deposit and promotion are commonly tied together under the bonus rules. Withdrawal can require completing wagering or cancelling the promotion.

With a non-sticky bonus, the casino commonly uses real cash first while keeping the bonus separate. If you win using only the cash balance, you may be able to withdraw those funds before the bonus is activated, usually by forfeiting the unused bonus.

Suppose two casinos both offer a €100 deposit plus €100 bonus.

At Casino A, the offer is sticky. The account enters bonus mode immediately and the withdrawal rules apply to the promotional balance.

At Casino B, the offer is non-sticky and cash-first. The player starts by wagering the €100 cash. If it becomes €150 before the bonus is touched, the terms may allow withdrawal of the €150 while cancelling the untouched €100 bonus.

Same headline. Different control over the deposit.

Why wagering requirements matter so much

A sticky bonus becomes much easier to evaluate once you calculate the actual wagering.

A phrase such as 35x wagering is incomplete unless you know what the multiplier applies to.

If it is 35x the €100 bonus:

35 × €100 = €3,500

If it is 35x the €100 deposit plus €100 bonus:

35 × €200 = €7,000

That is twice as much qualifying wagering even though both promotions can display “35x” prominently.

You should therefore look for wording such as:

• 35x bonus;
• 35x B;
• 35x deposit + bonus;
• 35x D+B.

Then check game contribution. If slots contribute 100%, €1 wagered generally counts as €1 toward the requirement. If a table game contributes only 10%, €1 wagered may reduce the requirement by only €0.10.

Can you withdraw before completing a sticky bonus?

Sometimes you can withdraw only after cancelling the bonus; sometimes additional restrictions apply.

The important point is that an early withdrawal normally does not allow you to preserve every part of the active promotion.

Before cancelling, check what happens to:

Your remaining deposit. Is it returned to cash balance or subject to another condition?

The bonus credit. It is commonly forfeited.

Winnings. Are winnings made while the bonus was active retained or removed?

Pending free spins or rewards. These may disappear when the promotion ends.

A player who does not check these rules can mistake “cancel bonus” for a harmless switch. It may be irreversible.

Why would a casino make a bonus sticky?

Casino bonuses are promotions, not unconditional transfers of cash. Operators use wagering and withdrawal conditions to control the cost of those promotions and reduce situations in which bonus funds are claimed without meaningful play.

A sticky structure gives the casino tighter control over how the promotion is used. The operator can offer a larger-looking balance while requiring the player to follow the promotion through to completion before withdrawing normally.

This does not tell you whether a particular offer is good or bad. It tells you that the headline bonus amount cannot be evaluated independently from the conditions.

A smaller bonus with lighter restrictions can be more flexible than a larger sticky bonus with demanding wagering.

What should you check before claiming a sticky bonus?

Start with the terms rather than the banner.

1. Wagering base

Does the multiplier apply to the bonus only, or to deposit plus bonus?

This can dramatically change the required turnover.

2. Maximum bet

Many promotions cap the amount that can be wagered per spin or hand while bonus conditions are active. Exceeding that limit can breach the terms even if the casino software technically accepts the bet.

3. Game contribution

Slots may count differently from blackjack, roulette, video poker or live casino games. Some games may be excluded completely.

4. Expiry period

A wagering requirement can become irrelevant if the bonus expires before you can reasonably complete it.

5. Maximum cashout or conversion

Some promotions limit how much bonus-derived value can become withdrawable.

6. Cancellation rule

Find out exactly what is forfeited if you cancel the promotion or request an early withdrawal.

7. Whether the bonus itself is cashable

Completing wagering does not always mean the original bonus credit becomes withdrawable. Some sticky bonuses remove that amount at the end.

Is a sticky bonus the same as a phantom bonus?

The terms are sometimes used loosely, but they are not necessarily identical.

A phantom bonus usually refers to bonus funds that cannot themselves be withdrawn. The credit can be used during play, but the original bonus amount is deducted before withdrawal.

A sticky bonus focuses more broadly on the way the promotion remains attached to the account or deposit while conditions are active.

A bonus can therefore be both sticky and non-cashable. But you should not assume every casino uses the terminology in exactly the same way.

When terminology is ambiguous, ignore the label and answer three questions:

1. Can I withdraw my deposit while the bonus is active?
2. Can the bonus amount itself become cash?
3. What happens to winnings if I cancel?

Those answers describe the real mechanics.

Is a sticky casino bonus bad?

Not inherently, but it is less flexible than a true cash-first structure when all other conditions are equal.

A sticky bonus can still have comparatively low wagering, generous game contribution, a reasonable expiry period, and clear withdrawal rules. A non-sticky bonus can still have high wagering and restrictive conditions after the bonus activates.

The better comparison is therefore not “sticky equals bad, non-sticky equals good.”

Instead compare the effective restrictions.

If you value the ability to keep your deposit separate from a promotion, the sticky structure is particularly important. If you intended to use the entire bonus package anyway, other terms such as wagering and maximum bet may matter more.

Why the displayed balance can be misleading

A casino account can show €200 without all €200 having the same legal or promotional status.

Part may be:

• deposited cash;
• cash winnings;
• bonus funds;
• locked bonus winnings;
• free-spin winnings;
• funds pending conversion.

The displayed total is therefore not always the same as the withdrawable balance.

This is especially relevant with sticky bonuses because the promotion can place restrictions on money that visually appears alongside ordinary cash.

When evaluating an account, look for separate labels such as “cash balance,” “bonus balance,” “locked,” “withdrawable,” or “wagering progress.”

The direct answer

So, what is a sticky bonus?

It is a casino promotion that remains attached to your account or deposited funds while the bonus conditions are active. In many implementations, your deposit cannot be withdrawn normally without first completing the wagering requirement or cancelling the promotion. The bonus itself may also be non-cashable, depending on the terms.

The important practical consequence is simple: claiming a sticky bonus can reduce the immediate flexibility of your own deposit.

Before accepting one, calculate the wagering requirement and read the withdrawal, cancellation, maximum-bet, game-contribution and cashout rules. Those conditions determine what the bonus is actually worth far more accurately than the percentage printed on the banner.
