Bonus EV — Sticky vs Cashable

The archetypes: Cashable, Sticky, and Phantom

Online casinos use flashy banners to hide the underlying rules of their promotions. Before you deposit a single dollar, you need to identify which of the three bonus archetypes you are claiming:

1. Cashable Bonus: The gold standard. Once you meet the wagering rollover requirements, the bonus money converts directly into real cash. You can withdraw the entire balance, including the deposit, your winnings, and the remaining bonus funds.
2. Sticky Bonus (Traditional): This bonus can never be withdrawn. It remains in your account indefinitely, acting as leverage to let you place larger wagers. When you request a withdrawal, your winnings are paid out, but the raw bonus amount stays behind in the casino vault.
3. Phantom Bonus (Parachute): The most common form of sticky bonus used by modern crypto casinos. The bonus is added to your balance, but the second you click “Withdraw,” the entire phantom bonus amount is permanently deleted from your balance.

The math: Withdrawal formulas

The calculator evaluates your expected net payout by applying the exact mathematical rules that casinos enforce during cashout requests.

1. Cashable cashout formula

Because the bonus converts to real cash, your final withdrawal limit is simply the total accumulated balance:

Withdrawal_Amount = Final_Balance

2. Sticky / Phantom cashout formula

When you request a withdrawal, the casino subtracts the initial bonus value from your total account balance. Your net cashout is:

Withdrawal_Amount = Final_Balance - Initial_Bonus_Value

If your final balance is less than the initial bonus value, your net withdrawal amount is exactly $0.

Data Sandwich: Why sticky bonuses require aggressive strategy

Let’s look at the math of two players who claim a 100% match up to $200. Both deposit $200 and start with a total balance of $400.

• Player A: Claims a **Cashable** bonus. They play safe, low-variance blackjack and finish their wagering with a final balance of $380. Because the bonus is cashable, they withdraw all $380, leaving them with a clean **+$180 net profit**.
• Player B: Claims a **Sticky** bonus. They play the exact same safe, low-variance style and also finish with a balance of $380. However, when they request a withdrawal, the $200 sticky bonus is deleted. Their final payout is $380 - $200 = $180. Subtracting their initial $200 deposit, they have ended up with a **-$20 loss**!

To make a sticky bonus profitable, Player B must play with **extreme variance** early on. They should place large, high-volatility bets (such as betting the full balance on a single roulette spin or aiming for massive slot multipliers).

If they lose, they only lose their deposit. If they win and swing their balance up to $1,000, they withdraw $1,000 - $200 = $800, securing a **+$600 net profit**. With a sticky bonus, grinding slowly is a mathematical guarantee of losing money.
