Sticky vs non-sticky bonuses: same headline, very different value
Two bonuses can have identical percentages, caps and wagering requirements and still be worth very different amounts. The difference is what happens to your own deposit — and it is often buried in a single sentence of the terms.
Definitions in plain English
A non-sticky bonus (also called a cash-first, parachute or "hybrid" bonus) keeps your deposit and the bonus in separate balances. You play with your cash first. If you win, you can withdraw the cash winnings at any time and simply forfeit the bonus. The bonus only comes into play if your cash runs out.
A sticky bonus merges deposit and bonus into one balance from the start. Your deposit is locked until the wagering requirement is met. When you finally withdraw, the bonus amount itself is usually removed from the balance — it "sticks" to the account but can never be cashed out. Some sticky bonuses keep the bonus withdrawable but still lock the deposit.
Why the order of play matters so much
Think of a non-sticky bonus as a free option. You start a session with $100 of your own money. If you hit a good win early — say your balance reaches $400 — you can walk away with $400 and ignore the bonus completely. If you lose the $100, the bonus switches on and you get a second, free attempt with the bonus balance. Either way you are never worse off than with no bonus at all, apart from the time rules.
A sticky bonus removes that option. The same early $400 win is locked inside the bonus balance, and you must keep wagering until the requirement is complete. All the extra turnover gives the house edge more time to grind the balance down, and if you bust, you lose your winnings as well as the bonus.
The option in one line
Non-sticky value ≥ sticky value, for the same terms
Because the non-sticky version lets you keep any early cash win and skip wagering entirely.
A worked example
Suppose a 100% bonus up to $100 with 35x wagering on the bonus, played on a 96% RTP slot, after a $100 deposit.
Scenario A — early win. Your first few dozen spins turn $100 into $300.
- Non-sticky: you withdraw $300. The bonus is forfeited. Profit: +$200.
- Sticky: your balance is $300 + $100 bonus = $400, but you still need $3,500 of wagering. Expected loss on that is $140, and the house edge plus volatility will often bust the balance before you finish. On average you end around $400 − $140 − $100 removed bonus = $160 — and with real busting risk, the typical outcome is lower.
Scenario B — early loss. Your $100 is gone within 60 spins.
- Non-sticky: the $100 bonus activates. You play it through, with an expected loss of $140 on the $3,500 required — so most of the time it busts, sometimes it finishes with a little cash. You were going to have $0 anyway, so any outcome is a bonus.
- Sticky: the merged balance would have dropped by the same amount; you continue with whatever remains of $200 total.
The non-sticky version captures the upside of early wins and still gives you a second chance after a loss. That asymmetry is worth real money, especially on high-variance slots where early swings are big.
How to tell which one you have
Terms rarely use the words "sticky" or "non-sticky". Look for these phrases instead:
| Phrase in the terms | Likely type |
|---|---|
| "Real money balance is used first" | Non-sticky |
| "You may withdraw your real balance at any time; the bonus will be forfeited" | Non-sticky |
| "Wagering applies to deposit + bonus" | Usually sticky or locked deposit |
| "The bonus amount will be deducted upon withdrawal" | Sticky |
| "Withdrawing before wagering is complete cancels the bonus and winnings" | Sticky |
If the terms say wagering applies to deposit plus bonus, assume your deposit is locked and treat the offer as sticky in practice, even if the bonus itself becomes withdrawable. Our review of Lucky Block walks through exactly this case.
Gradual-release bonuses
A third design releases the bonus in slices as you wager, moving each slice to your cash balance. BC.Game uses a version of this. It sits between the two: your deposit stays playable, and you bank part of the bonus progressively instead of all-or-nothing at the end. Mathematically it lowers the variance of the outcome, which makes the simple expected-value figure a more reliable guide.
What this means for our rankings
Our calculator computes the linear expected value, which is the same for sticky and non-sticky bonuses with identical terms. In the rankings we therefore treat stickiness as a tie-breaker and a ranking factor rather than a number in the score: between two offers with similar scores, the non-sticky one ranks higher. All bonuses at BitGuruz are subject to its terms and conditions, including wagering requirements, so check the current terms on the site for how your deposit is treated; if it is locked into the wagering, plan for that exactly as described above — one reason we describe that bonus as optional even though BitGuruz is #1 in our rankings.
Strategy for each type
Non-sticky: play your cash first at your normal stakes. If you hit a meaningful win, consider withdrawing and forfeiting the bonus — this is the main reason non-sticky bonuses are valuable. If your cash runs out, play the bonus with modest stakes under the max bet and see where it goes.
Sticky: commit to the full requirement before depositing, because you cannot change your mind cheaply. Use the highest-RTP eligible slots, keep stakes low enough to survive variance, and plan the pace against the time limit. If the expected value is negative, consider declining the bonus — playing with cash keeps every withdrawal option open.
Common misunderstandings
- "Non-sticky means no wagering." No — the bonus still has a requirement; it just does not apply to your cash.
- "Sticky bonuses are scams." Not necessarily. They are simply worth less than the same terms on a non-sticky basis, and they suit players who intend to play the full requirement anyway.
- "I can cancel a sticky bonus whenever I like." Often you can, but cancellation usually removes winnings made while the bonus was active. Read the clause before you start.
The takeaway
When comparing two offers with similar numbers, the one that plays your cash first is worth more. Check the order-of-play clause every time, add it to your notes next to the multiplier and base from the wagering requirements guide, and remember that max bet rules apply in both designs — see max bet rules. And whatever the type, a bonus is still gambling: set a budget before you play. Our responsible gambling page explains how.
Frequently asked questions
What is a non-sticky casino bonus?
A bonus held separately from your deposit. Your cash is played first and can be withdrawn at any time by forfeiting the bonus; the bonus only activates if your cash runs out.
What is a sticky bonus?
A bonus merged with your deposit into one balance. The deposit is locked until wagering is complete, and the bonus amount is usually deducted when you withdraw.
Which is better, sticky or non-sticky?
Non-sticky, for the same terms. It gives you the option to keep early cash wins without wagering, which is worth real money.
