Claiming a massive casino bonus is incredibly exciting, but the free money always comes with a catch.

Also known as "playthrough" or "rollover," this rule dictates exactly how and when you can withdraw funds.
Defining the Playthrough Rule
It is expressed as a number (e.g., 30x) indicating how many times you must wager the bonus amount.

For example, a $50 bonus with a 40x playthrough means you need to generate $2000 in betting volume.
It prevents instant withdrawals of free casino fundsThe multiplier usually ranges from 20x to 50xIt can apply to the bonus alone or the deposit plus bonus Game Contributions and Weighting
Because blackjack has a tiny house edge, playing it is generally heavily restricted when using bonus funds.

However, table games like roulette or baccarat might only contribute 10% or be excluded entirely.
Time Limits and Maximum Bets
Wagering requirements must usually be met within a strict timeframe, often 7 to 30 days.

Furthermore, there is almost always a maximum bet limit in place while a bonus is active.
