I never took bonus wagering requirements all that seriously. But I did get freerolls for sports betting a few times. The problem was that I wasn't planning to play slots at those casinos, and they felt unfamiliar to me. As a result, I had to deposit money into my slots balance just to withdraw the few pennies I'd won. And of course, I ended up losing everything I put into slots there.
Exactly when there is a wagering requirement with a bonus, it is no longer a bonus, it is their marketing policy. And for this reason if I try a casino, I try not to take their deposit bonus, Because if I take a deposit bonus I have to bet on their preferred games and at the end of the day, I lose my deposited money. So it is better for me to make a deposit and play any game I want.
That's true. I only take a bonus if it doesn't require me to do something I hadn't planned to do. And I'll play freerolls like that if I have free time for them.
For the most part, I don't get anything interesting from casinos - their bonuses just make me place more bets, play games I don't like, or do something else that boosts the casino's profit or at least undermines my strategy.
