The difference between a sticky and a non-sticky bonus is one of the most important things to understand before claiming any casino welcome offer. It affects how your funds are structured from the moment you deposit, what options you have if you run up a big win early, and how the wagering requirement is eventually cleared. Yet most sites explain the distinction in one or two sentences and move on.
This guide goes further. After eight years working inside the iGaming industry, including time at an operator where bonus structures were designed and tested, I want to explain not just what these bonus types are but what they mean in practice, which is better for which type of player, and how to spot the difference in casino bonus terms before you commit.
A non-sticky bonus, sometimes called a detachable bonus or parachute bonus, keeps your deposited funds and your bonus funds separate at all times. They exist in parallel in your account rather than being merged together.
This separation matters because it defines when you can still withdraw. As long as you haven’t touched the bonus balance, you can cash out at any point. If you deposit €100 and receive a €100 bonus, you’ll play through your deposit first. Any winnings made during that phase can be withdrawn without needing to meet wagering requirements.
However, once your deposit is lost and you begin playing with the bonus funds, the situation changes. From that point on, your balance is tied to the bonus, and you’ll need to complete the wagering requirement before you can withdraw anything.
Here is why that matters in practice:
You deposit €100 and receive a €100 non-sticky bonus. You start playing and, before you have lost down to the bonus balance, you run good, and your balance reaches €300. You now have a decision to make. You can continue playing with the intention of clearing the wagering requirement and withdrawing everything. Or, if the timing feels right and you are happy with what you have made from your deposit alone, you can withdraw your deposit and forfeit the bonus.
This flexibility is the core advantage of a non-sticky bonus. It is not that the bonus itself is more generous, it is that you retain control over your own deposit throughout the session.
Non-sticky bonuses are increasingly the preferred structure among experienced and regular casino players, particularly at MGA-licensed casinos where the format has become more common.
A sticky bonus merges your deposit and bonus funds together from the moment the bonus is credited. There is no separation. You have one combined balance, and the entire balance must work through the wagering requirement before any withdrawal is possible.
Using the same example: you deposit €100 and receive a €100 sticky bonus. You now have €200 as a single merged balance. If you run up your balance to €300 midway through the session, that €300 is not accessible until the wagering requirement is cleared in full. You cannot extract your deposit from it independently.
The word "sticky" comes from exactly this: the bonus is stuck to your deposit. You cannot peel them apart.
This does not make sticky bonuses worthless. They are simply structured differently, and there are situations where they work in a player's favour. But they do remove the flexibility that non-sticky bonuses provide, and in exchange, sticky bonuses are often larger or come with higher match percentages to compensate.
Let's put both bonus types through exactly the same scenario to show how the experience differs.
The setup:
Scenario: You have a great early session and your balance reaches €350 after only wagering €50 in bets.
With a non-sticky bonus: Your €100 deposit is separate. You haven’t touched the bonus money. You decide the €350 balance is a good result and you want to secure it. You request a withdrawal. The bonus is forfeited (€100), and you receive €250 back.
With a sticky bonus: Your balance is €350 as a single merged amount. You have wagered €50 of the €3,000 required. You cannot withdraw anything. To access any of that €350, you must continue playing through the remaining €2,950 in required wagering. The session continues. Whether you reach €3,000 in bets with €350, €50, or €0 remaining is now determined by how the next €2,950 of play goes.
This example shows why experienced players generally prefer non-sticky bonuses when the terms are otherwise equal. The option to exit with your deposit is valuable in a way that is easy to underestimate until you are actually sitting on a winning session with a merged balance you cannot touch.
Some casinos use a structure that sits between the two, sometimes marketed as a half-sticky or split bonus. Casumo uses this format, for example.
With a half-sticky bonus, when you reach the withdrawal stage, the bonus amount is automatically removed from your balance but your winnings are paid out in full as cash. So if you have wagered the full requirement and your balance is €180, the €100 bonus is deducted and you receive €80. If your balance is €220, the €100 bonus is deducted and you receive €120.
This means you can never withdraw the bonus amount itself, but all winnings it generates are real cash once the wagering is cleared. It sits between sticky and non-sticky in terms of player friendliness, and is worth understanding if you see a casino marketing it as a separate bonus type.
The honest answer is that it depends on what kind of player you are and how you plan to use the bonus. But I will give you a direct opinion rather than sitting on the fence.
For most players, non-sticky bonuses are the better structure. The ability to withdraw your deposit at any point is a meaningful safety net. Casino sessions are unpredictable. If you have a strong start and want to secure your position, a non-sticky bonus lets you do that. A sticky bonus locks you in regardless of how the session is going.
Sticky bonuses suit players who are specifically chasing the bonus value and are comfortable with full commitment. If your intention is to work through the wagering requirement regardless and you are treating the full balance as the stake, the sticky structure is not a disadvantage. Some of the most generous welcome offers on the market are sticky bonuses, as operators can afford to offer larger bonuses when they know players cannot exit early.
The wagering requirement matters more than the bonus type in many cases. A sticky bonus with 5x wagering is far more attractive than a non-sticky bonus with 50x wagering. Do not let the sticky vs non-sticky distinction override the fundamental maths of what you are being asked to wager.
At JustCasinoSites, we list the bonus type clearly on every casino and bonus page alongside the wagering requirement. The combination of the two is what tells you whether an offer is genuinely worth taking.
Casinos are not always consistent in how they label these bonus types, and some do not use either term explicitly. Here is what to look for in the terms and conditions.
Signs of a non-sticky bonus:
Signs of a sticky bonus:
If the terms are unclear, contact live chat before depositing and ask directly: "If I want to withdraw my deposit before the wagering requirement is complete, can I do so, and what happens to the bonus?" The answer will tell you which structure you are dealing with.
Bonus hunting, the practice of claiming bonuses with the specific intention of completing wagering requirements as efficiently as possible, is affected significantly by bonus type.
Non-sticky bonuses are generally preferred for bonus hunting because the exit option provides a floor. If you run up a strong balance early, you can cash out your winnings and exit. The downside risk is capped at your deposit regardless of what happens during the bonus clearing process.
Sticky bonuses remove that floor. A committed bonus hunter playing a sticky bonus is fully exposed to variance across the entire wagering period. A losing streak that depletes the balance before the requirement is met results in losing both the bonus and the deposit.
This does not mean sticky bonuses cannot be profitable to hunt, but the risk profile is meaningfully different.
We tag every bonus with its type across the site. For a full list of casinos currently offering non-sticky bonuses, see our dedicated Non-Sticky Bonus Casinos page. For sticky bonus offers, including some of the highest-value welcome packages currently available, see our Sticky Bonus Casinos page.
A few notable examples currently listed:
Casinostars offers a 100% up to €300 with a 5x wagering requirement on a non-sticky structure. It’s one of the most player-friendly combinations on the site at present.
Mondcasino's welcome offer is sticky but carries just a 5x wagering requirement, making it among the easiest to clear of any bonus currently listed. The low wagering largely offsets the sticky structure.
These details are verified by our editorial team and updated when casino terms change.
Wager-free bonuses (0x wagering) are a separate category that sits outside this sticky vs non-sticky framework entirely. With a wager-free bonus, there is no playthrough requirement at all. Winnings from the bonus are credited as real cash and can be withdrawn without condition.
Wager-free bonuses tend to be smaller in headline value because the casino is taking on more risk. But they are the most transparent bonus type available and worth seeking out if you prefer simplicity over bonus size.
Sticky and non-sticky bonuses are not inherently good or bad. They are different structures with different implications for how you can manage your session.
Non-sticky bonuses keep your deposit separate and give you the option to exit early if you win (or just want to cut your losses), forfeiting the bonus but recovering your deposit + any winnings. This flexibility makes them the generally preferred choice for most players.
Sticky bonuses merge everything into a single balance from the start. They are often larger or come with better headline terms to compensate, but they commit you fully to the wagering process with no early exit option.
When evaluating any welcome offer, look at the bonus type and wagering requirement together, not in isolation. A well-structured sticky bonus with low wagering can be a better deal than a non-sticky bonus with a punishing playthrough. Check the terms, run the numbers, and if anything is unclear, ask the casino's live chat before depositing.
