Key Takeaways

  • Non-sticky bonuses are mathematically superior for most players due to withdrawal flexibility – you can cash out real money winnings anytime
  • Sticky bonuses require high-variance strategies to overcome negative expected value – aim for big wins early then switch to conservative play
  • Wagering requirements matter more than bonus size – a smaller non-sticky bonus with 25x wagering beats a large sticky bonus with 40x wagering
  • Game selection dramatically impacts value – blackjack with 0.5% house edge vs slots with 4% house edge can swing EV by 200%+

What is a Sticky Bonus?

Understanding phantom bonuses

A sticky bonus (also called a phantom bonus or non-cashable bonus) is a promotional offer where the bonus funds are added to your deposit for wagering purposes but cannot be withdrawn. When you request a withdrawal, the original bonus amount is deducted from your balance – only winnings generated from playing with the combined balance are cashable. For example, if you deposit $100 and receive a $100 sticky bonus, you play with $200 total. If you complete wagering and have $250, you can withdraw $150 ($250 minus the $100 bonus amount).

Sticky Bonus Example

Your Deposit:$100
Sticky Bonus:$100
Total Playing Balance:$200
After Wagering Balance:$250
Minus Sticky Bonus:-$100
Withdrawable Amount:$150

Alternative Names

Sticky bonuses are also called: Phantom Bonus, Non-Cashable Bonus, Play-Only Bonus

What is a Non-Sticky Bonus?

Understanding cashable bonuses

A non-sticky bonus (also called a cashable bonus, parachute bonus, or freeplay bonus) keeps your deposit and bonus funds in separate balances. You wager with your real money first, and only after losing your deposit do bonus funds activate. Crucially, you can withdraw real money winnings at any time without meeting bonus wagering requirements. If you win before needing the bonus, you simply forfeit the unused bonus and cash out your profits immediately.

Non-Sticky Bonus Example

Initial Setup:
Real Money Balance:$100
Bonus Balance (Separate):$100
Scenario: You Win Early
Real Money After Playing:$300
Can Withdraw Immediately:$300
✓ Bonus is forfeited but not required. No wagering needed!

Alternative Names

Non-sticky bonuses are also called: Cashable Bonus, Parachute Bonus, Clear Bonus, Lifeline Bonus, Freeplay Bonus

Mathematical Comparison

Understanding the real value difference

Consider a $500 deposit with a $500 bonus and 30x wagering on a 4% house edge slot game. With a sticky bonus, you play with $1,000 total and must wager $15,000 (30x $500). Expected loss is $600, leaving $400 final balance. Subtract the $500 sticky bonus, and you have a -$100 expected value. With a non-sticky bonus, if you win $700 with your deposit (reaching $1,200), you can withdraw immediately. You only use the bonus if your deposit is lost, giving you a second chance. This withdrawal flexibility typically makes non-sticky bonuses mathematically superior.

Sticky Bonus Math

Setup:
  • • Deposit: $500
  • • Bonus: $500 (sticky)
  • • Wagering: 30x bonus = $15,000
  • • House Edge: 4% (slots)
Calculation:
  • • Starting: $1,000
  • • Expected Loss: $600
  • • Final Balance: $400
  • • Minus Bonus: -$500
Expected Value:-$100

Non-Sticky Bonus Math

Setup:
  • • Deposit: $500
  • • Bonus: $500 (non-sticky)
  • • Wagering: 35x bonus = $17,500
  • • House Edge: 4% (slots)
Scenario A (Win Early):
  • • Win to $700 with deposit
  • • Withdraw immediately: $700
  • • Probability: ~40%
  • • Profit: +$200
Expected Value:+$80

Why Non-Sticky is Better

  • Withdrawal Flexibility: Cash out real money winnings anytime without completing wagering
  • Lower Risk: Bonus serves as insurance – only use it if you lose your deposit
  • Positive EV Possible: With optimal play, non-sticky bonuses can have positive expected value
  • Option Value: The ability to quit while ahead has monetary worth

When to Choose Each Type

Strategic bonus selection

Choose Sticky Bonuses When:

1. Playing High-Volatility Slots

If you plan to play high-variance slots with large bets, sticky bonuses give you significant extra capital for big swings. The strategy is to hit a large multiplier early (100x+), then complete wagering conservatively.

2. Low Wagering Requirements

Sticky bonuses with 20x or lower wagering become more valuable. At these levels, the expected loss is minimal and the extra capital provides real advantage.

3. Large Deposit Amounts

High rollers depositing $5,000+ can benefit from sticky bonuses providing $2,500-$5,000 extra capital, even with the non-cashable restriction.

Choose Non-Sticky Bonuses When:

1. You're Risk-Averse

Non-sticky bonuses provide a safety net without commitment. Play conservatively with your deposit, and only use the bonus if needed.

2. High Wagering Requirements

When facing 40x+ wagering, the withdrawal flexibility of non-sticky bonuses becomes extremely valuable. You can escape before grinding through excessive requirements.

3. Uncertain Time Availability

If you might need to withdraw before completing wagering, non-sticky bonuses let you cash out real money winnings anytime.

Real Player Scenarios

Practical examples with outcomes

Low Roller - Sticky Bonus

Setup:

$200 deposit + $200 sticky bonus (30x = $6,000 wagering). Playing $2/spin slots with 4% house edge.

Strategy:

Switch to $5 bets on high-volatility slot. If balance reaches $800+, reduce to $1 bets to complete wagering.

Outcome:

30% success rate with $300-500 profit when successful. Overall EV: -$40

High Roller - Non-Sticky

Setup:

$5,000 deposit + $2,500 non-sticky bonus (35x = $87,500 wagering). Playing $100/hand blackjack with 0.5% house edge.

Strategy:

Play with deposit first. If ahead $1,000+ (balance ≥ $6,000), withdraw immediately. 45% success rate.

Outcome:

Average withdrawal $6,200 when successful. Overall EV: +$1,333 (26.7% ROI)

Frequently Asked Questions

Which type of bonus is better for beginners?

Non-sticky bonuses are generally better for beginners because they offer withdrawal flexibility. You can play conservatively with your deposit, and if you win, you can cash out immediately without completing bonus wagering requirements. The bonus acts as insurance if you lose your deposit.

Can I profit from sticky bonuses?

Yes, but it requires high-variance strategies. Sticky bonuses typically have negative expected value, but you can overcome this by aiming for big wins early (100x+ multipliers) then switching to conservative play to complete wagering. Success rates are typically 30-40%, but profitable when successful.

Do all casinos clearly label bonus types?

No, many casinos don't explicitly state whether a bonus is sticky or non-sticky. Always read the full terms and conditions. Look for phrases like "bonus is forfeited upon withdrawal" (sticky) or "real money is played first" (non-sticky). When in doubt, contact customer support before claiming.

What if I want to cancel a sticky bonus?

Most casinos allow you to forfeit a sticky bonus, but you typically lose your entire balance (deposit + bonus + winnings). Read the terms carefully. Some casinos let you forfeit the bonus and keep your deposit, while others don't allow cancellation at all once activated.
