An online casino bonus is conditional credit, not free money. You receive extra funds or free spins, but you must wager a multiple of the bonus, and sometimes of your deposit too, before the bonus balance or any winnings tied to it become withdrawable cash. That multiple is the wagering requirement, also called playthrough or rollover. Everything else in the terms exists to define how that multiple is counted.

The single most important detail is which amount the multiplier applies to, because the same advertised number can mean two very different totals. Take a 100 dollar deposit with a 100 percent match, giving a 100 dollar bonus, at 30x wagering. If wagering is on the bonus only, the requirement is 100 x 30 = 3,000 dollars of bets. If wagering is on deposit plus bonus, it is (100 + 100) x 30 = 6,000 dollars of bets. Double the volume, same headline offer. Always find the base before you judge an offer.

The worked example most guides skip is game contribution, and it is where players get caught. Wagering is not just total bets placed; it is total qualifying bets. Slots usually count 100 percent, but table games often count far less. If blackjack counts 10 percent, then clearing a 3,000 dollar requirement by playing blackjack alone needs 3,000 divided by 0.10 = 30,000 dollars of bets. Ten times the headline figure, from one line of the terms. Check the contribution of the games you actually intend to play, not just the headline multiplier.

Two more terms set the real price. Maximum bet: many bonuses cap each spin or hand while wagering, often around 5 dollars, and exceeding it can void the bonus and its winnings. At a 5 dollar maximum, clearing a 3,000 dollar requirement takes at least 3,000 divided by 5 = 600 spins or hands, even before losses. Time limit: requirements commonly expire within days or weeks, and unmet wagering means the bonus and its winnings are removed.

Free spins work the same way one step removed. Suppose 50 free spins produce 20 dollars of winnings, and those winnings carry 40x wagering. You must then wager 20 x 40 = 800 dollars before that 20 dollars can be withdrawn. No-deposit offers add a further trap: a maximum cashout cap, so even after meeting wagering you may only be allowed to keep a fixed amount of the winnings.

A final distinction is sticky versus non-sticky bonuses. With a sticky bonus, once wagering is complete you can withdraw your winnings, but the bonus amount itself is removed. With a non-sticky bonus, you play with your own deposit first, and you can withdraw deposit winnings before touching the bonus, which is the fairer structure. If the terms do not say which type it is, assume sticky.

Before claiming any bonus, run this five-line check: the bonus amount, whether wagering is on bonus only or deposit plus bonus, the total wagering in currency, the contribution of your games, and the maximum bet and time limit. If the effective volume cannot fit inside the time limit at the allowed bet size without turning play into a grind, decline the bonus. A bonus never changes the odds of the games themselves; it only buys you more rounds in exchange for more turnover.
