Why can't I withdraw my winnings even though the bonus terms seemed clear?

A wagering requirement specifies how many times you must bet through a bonus (and sometimes your deposit too) before you can withdraw related winnings. What often catches players out isn't necessarily hidden or fraudulent, but the compounding effect of several separate conditions: different games may count toward the requirement at different weighted percentages (a slot might count 100% while table games count 10% or 0%), a maximum bet size while the bonus is active may be much lower than you'd expect, and the entire wagering requirement may need completing within a shorter time limit than users assume.

Breaching any single condition, even unknowingly, commonly voids the bonus and any related winnings under the terms you agreed to when opting in. This is usually legitimate under the stated terms, even though it feels like a trap after the fact, which is why reading the full terms before opting into any bonus matters far more than most players expect.

Where this crosses from 'unfavorable but legitimate terms' into a real dispute is if the casino applies conditions that weren't actually stated in the terms you accepted, retroactively changes the terms after you've started wagering, or cannot show you the specific term you supposedly breached when you ask.
