How Do Online Casino Bonuses Work?
Deposit matches, free spins, reloads and cashback explained — including wagering requirements, game contribution and sticky terms, so you know what an offer is really worth before you claim it.
Wagering requirements explained: what rollover means, how game contribution changes the maths, and how to work out what a bonus is really worth before you claim it.
A wagering requirement — also called rollover or playthrough — is the total amount you must bet before money linked to a casino bonus can be withdrawn. It is written as a multiplier, such as 20x or 30x. Multiply the qualifying amount by that number and you get the volume of eligible wagers you need to place before requesting a payout.
The multiplier itself is simple arithmetic. What makes wagering requirements confusing is everything around them: which amount the multiplier applies to, which games count, how much each game counts for, and what happens to the bonus once you finally withdraw.
Every requirement has two parts: a multiplier and a base amount.
The multiplier is the headline number in the terms, written as 20x, 30x, 40x and so on. The base amount is what the multiplier is applied to, and casinos do this in one of two ways:
The second method produces a bigger number from a smaller-looking multiplier, which is why the base amount matters as much as the multiplier. A 20x requirement on deposit plus bonus is heavier than a 30x requirement on the bonus alone in the example above. Always read the sentence that defines the base before comparing two offers.
Note that "wagering" means the total value of the bets you place, not money you lose. If you bet $1 a spin, win some rounds and lose others, every $1 staked counts toward the target regardless of the outcome. This is why a balance can cycle through the requirement several times over even when the amount you deposited barely moves.
Without a playthrough condition, a deposit bonus would be free money. A player could deposit, claim the match, withdraw everything and repeat. The requirement converts a promotion into an invitation to play rather than a cash transfer, and it is the reason bonus funds sit in a separate, restricted part of your balance until the condition is met.
Two related terms usually travel with the requirement:
Most casino welcome offers are sticky, so read that line carefully. It changes the arithmetic of what you can actually cash out.
Casinos publish a contribution table showing how much of each dollar wagered counts toward the requirement. Games with a low house edge or with strategies that reduce risk contribute less, because otherwise a player could clear a bonus cheaply on near-even-money bets.
This is the contribution table used at Lunaris:
| Game category | Contribution per $1 wagered |
|---|---|
| Non-progressive slots | 100% |
| Video poker | 20% |
| Blackjack (RNG variations) | 10% |
| Roulette | 10% |
| Live games | 1% |
Read that table before you choose where to play. At 100%, a $10 slot spin clears $10 of the requirement. At 10%, a $10 roulette bet clears $1. At 1%, a $10 live game bet clears 10 cents — you would need $100,000 in live bets to clear a $1,000 requirement, which is why bonus play and live dealer play generally do not mix.
Here is a full pass through a typical offer, using the terms that apply to a Lunaris slots bonus.
Now translate that into play. At a $1 stake per spin on a non-progressive slot contributing 100%, $4,000 of wagering is 4,000 spins. At $2 per spin it is 2,000 spins. Neither figure tells you whether you will finish ahead — that depends on the game's return to player and volatility and on ordinary randomness — but it does tell you how much play the offer commits you to.
Change one variable and the picture shifts. If you spent the same $4,000 on RNG roulette at 10%, you would clear only $400 of the requirement and would need $40,000 in roulette bets to finish. A courtesy bonus works the same way on a smaller base: a $100 bonus with a 20x requirement on the bonus alone is $2,000 in wagers.
In short
Multiplier x base amount = your target. Contribution percentage decides how fast each bet moves you toward it.
The multiplier is one line in a longer set of conditions. These are the terms that most often surprise players:
A 400% headline reads bigger than a 100% one, but the cash ceiling, the base amount and the contribution table decide the real value.
Unless a specific promotion states otherwise, all Lunaris bonuses carry a 20x wagering requirement, calculated on your deposit amount plus your bonus amount. The minimum deposit to receive a bonus is $100 and the maximum bonus issued is $100. Bonuses are sticky: the bonus amount itself is not withdrawable and is removed during the withdrawal approval process, so what you cash out is the winnings it helped produce.
Contribution follows the table above, which means the slots library is where a bonus is designed to be played. Bonuses are not available on live casino games, so if you want to spend an evening at a live dealer table, play that balance without a bonus attached. Individual promotions on the promotions page may set different requirements, cashout caps or eligibility rules, and those terms take priority over the default.
Bonuses are optional. Depositing without one leaves your balance free of playthrough conditions and subject only to the standard withdrawal limits shown in the Cashier. If a promotion's terms are unclear, [email protected] can confirm them before you claim rather than after.
