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

Understanding this mathematical concept is absolutely critical if you ever want to successfully cash out a bonus.

Defining the Playthrough Rule

The casino requires you to risk the bonus money multiple times before it converts into real, withdrawable cash.

If you receive a $100 bonus with a 20x wagering requirement, you must place $2000 in total bets.

• It prevents instant withdrawals of free casino funds
• The multiplier usually ranges from 20x to 50x
• It can apply to the bonus alone or the deposit plus bonus

Game Contributions and Weighting

Casinos assign different "weighting" percentages to various games based on their inherent house edge.

If a game contributes 10%, a $10 wager only removes $1 from your remaining playthrough total.

Time Limits and Maximum Bets

Wagering requirements must usually be met within a strict timeframe, often 7 to 30 days.
