The Sticky Model

A sticky bonus — sometimes called a phantom bonus — is added to your balance for wagering purposes but can never be withdrawn itself. You play with the combined total of your deposit plus the bonus, and when you eventually cash out, the bonus amount is subtracted first. The bonus is effectively extra ammunition, not extra money: it lets you place bigger bets and survive longer losing streaks, but only the winnings above it are ever yours. Most traditional deposit matches at crypto casinos work this way unless stated otherwise.

The Non-Sticky Model

A non-sticky bonus keeps your deposit and the bonus in separate balances, and you play with your real money first. If you win with your own funds before touching the bonus, you can withdraw immediately and simply forfeit the unclaimed bonus — no wagering required. Only if your deposit runs out does the bonus balance activate, at which point its wagering requirements kick in. This structure is dramatically more player-friendly, because your own money is never held hostage by bonus terms.

A Worked Example

Imagine a 100% match on a 0.001 BTC deposit, giving 0.001 BTC in bonus. Under a sticky structure, you play with 0.002 BTC combined; if you run it up to 0.005 BTC and withdraw, the casino deducts the 0.001 BTC bonus and you keep 0.004 BTC. Under a non-sticky structure, you play the 0.001 BTC deposit first; if you double it to 0.002 BTC before touching the bonus, you withdraw the full 0.002 BTC with zero wagering and abandon the bonus. Same headline offer, completely different outcomes — which is why the structure matters more than the percentage.

Which Suits Which Player

Non-sticky bonuses suit almost everyone: casual players who might hit an early win and want out, and bonus-skeptics who value freedom over headline size. Sticky bonuses can suit high-variance players who specifically want the biggest possible starting bankroll for a long session and accept the lock-in — but they should be claimed with eyes open. If you are comparing offers, a smaller non-sticky bonus is frequently better real value than a larger sticky one. Our guide to deposit match bonus claims walks through evaluating the full package.

How to Tell Them Apart

Casinos do not always label the structure clearly, so you have to read the terms. Look for phrases like bonus funds are deducted upon withdrawal (sticky) versus play with real money first or forfeit the bonus to withdraw (non-sticky). Check whether withdrawing is blocked entirely while the bonus is active — a hallmark of sticky structures — or freely available with bonus forfeiture. If the terms are ambiguous, ask support directly and keep their written answer. Also compare against related offer types like reload bonuses and the welcome bonus wagering terms, which follow the same structural logic.

Strategy Implications

With a sticky bonus, your only rational approach is to play through the wagering as efficiently as possible on eligible games, since withdrawing early is impossible. With a non-sticky bonus, the optimal strategy is inverted: play normally with your deposit, and treat the bonus as a free second chance that only matters if the first chance fails. Never increase stakes to chase wagering on a sticky bonus beyond your comfort level — the bonus is not worth real-money distress. Structure dictates strategy, so always identify the structure before the first bet.
