Marie didn't say she was looking for a bonus...
And anyway, the vast majority of Rivals these days have ludicrous wagering requirements on their bonuses, with many being Phantom and/or having very low maximum cash-out amounts.
At most Rival casinos players are better off NOT taking their bonuses.
There are quite a few Rivals I would highly recommend in addition to those mentioned above; Superior, Da Vinci's Gold, Vegas Sky, Dom Game and a few others.
But if you're not interested in bonuses, then I would agree Slots Capital is the safest and fastest paying of the lot!
