Is the 250% first deposit bonus a free one? Like, is it one that comes without any wager requirements?
Asking because to me personally, I sometimes see or perceive such bonuses as a gambling trap, which when a gambler falls into it, he or she will be forced to gamble to meet a certain target, even when such a gambler shouldn't be gambling, this is one of the reasons why I usually try as much as possible to avoid such bonuses.

And I think it's only normal that when ever such bonuses are being advertised, making sure to include the terms and conditions that goes with it, so that any user who is interested in taking advantage of it, can find and read all the important informations that goes with the bonus, so that he or she can decide for sure whether the bonus is something he or she did like to take advantage of, or just ignore.
