Looking up "bonus max bet" usually happens after a bonus has vanished, taking its winnings with it. That alone is no sign of a rigged game; the usual cause sits in the terms: an expired deadline, an early withdrawal, a winnings cap or an irregular play clause, and the transaction history and support record are worth checking. Each of these can be seen in advance, and a short read of the terms shows which of them apply to a given offer.
Requesting a withdrawal while a bonus is active often cancels the bonus and everything won with it, and some casinos apply the rule even to cash deposited alongside it. A player can usually cancel a bonus on purpose from the account page, which frees the cash balance at the cost of the bonus. Knowing where that option sits, and what it does to winnings, turns an accidental forfeit into a choice made knowingly.
Many bonuses limit how much can be withdrawn from winnings made with them, often as a multiple of the bonus or a fixed amount. Winnings over that limit are taken back at conversion, even after the full requirement has been met. The cap is easy to miss because it sits in the general terms, not the offer page, and a bonus calculator that leaves it out overstates what the offer is worth. On a small bonus it can make a large win on a volatile game worth only a fraction of its size.
Every bonus has a deadline, and usually two: one for claiming it and one for completing its wagering requirement. When the second passes, the bonus and any winnings still tied to it are removed, however close the player was to meeting the requirement. Whether the bonus works as free spins or as a deposit match, deadlines range from a day for spin winnings to several weeks for a large match. The clock often starts at the deposit, which means a slow first session already uses part of the available time.

Typical examples include betting both sides of an even money bet, switching to low risk play to clear wagering, or sharply raising stakes after conversion.
A saved copy proves which version of the terms applied on the day the offer was taken, which matters if the casino later changes them.

Often yes. Asking to withdraw while a bonus is active can remove the bonus and its winnings, and some casinos apply this to the deposited cash too.
