<p>Wagering requirements are the single most important number in any casino bonus, and the one most players ignore until it is too late. This guide explains exactly how they work, with examples.</p><h2>What wagering requirement means</h2><p>A wagering requirement (sometimes called playthrough or rollover) is how many times you must bet a bonus before you can withdraw any winnings from it. It is shown as a multiplier such as 30x or 40x.</p><h2>How to calculate it</h2><p>Take the bonus amount and multiply it by the requirement. A <strong>£20 bonus with 35x wagering</strong> means you must place <strong>£20 x 35 = £700</strong> in bets before the bonus winnings become withdrawable. Some offers apply the multiplier to the deposit plus bonus, which is stricter, so always check which.</p><h2>Game weighting changes everything</h2><p>Not every game counts the same toward wagering:</p><ul><li><strong>Slots:</strong> usually count 100%.</li><li><strong>Roulette, blackjack and table games:</strong> often count 10% or less, or are excluded.</li><li><strong>Live casino:</strong> frequently excluded entirely.</li></ul><p>So a low 20x bonus that only counts slots can be easier to clear than a 35x bonus that excludes most games.</p><h2>What a fair bonus looks like</h2><ul><li>Wagering of <strong>35x or lower</strong>.</li><li>Applied to the <strong>bonus only</strong>, not deposit plus bonus.</li><li>A reasonable <strong>time limit</strong> (7 days or more).</li><li>A sensible <strong>max bet</strong> while wagering (commonly £5).</li></ul><p>Wager-free offers exist too, where any winnings are yours to keep with no playthrough. Our bonus pages flag the wagering on every offer so you can compare at a glance.</p>
