Oh, and if you deposit the full $600 the bonus is paid out in $20 increments so there's no real pressure to clear the whole thing.

And now some calculations just to show that it works even if you don't clear the whole bonus. Aren't you glad I'm bored and don't want to work?

Say you play $200 worth of SnGs. (that's $200 in fees or 200 $10+1 SnGs)

Rakeback would give you 200*.27 = $54
You would earn 1400 points which is worth $84 in bonus. They pay in $20 increments so you'd be paid $80 of it. You would then get rakeback on (200 - 80 = 120 ) which comes out to $32.4.

Bonus $80
Rakeback $54
Bonus + Rakeback $112.40

Bottom line is that there is no way in hell that bonus + rakeback is not your best option.
