I can't help but feel that I may be one of those that Percival12 was mentioning, so you all get to read my two cents now. I agree with vacant1 - I will rarely play with a bonus. When I do, its usually at a Rival or Top Game casino and I deposit less than $50 only. I hate being restricted by playthrough requirements. I have also narrowed down my list of casinos I deposit at. By doing this, it seems to be working in my favor. Microgaming casinos, by far, offer the best payout percentage (in my opinion). One more thing, I have developed a silly superstition... by taking a deposit bonus I am sabotaging my chances of having a good run (consecutive big hits in one night). I have nothing to substantiate my theory, but its uncanny how it always turns out that way for me.
