bet365 first time deposit rake question

okay i know that the november bonus of 100 requires u to play at least 1/2 limit for u to clear it. Since it will be my first tiem depositing there for a 50 dollar first time deposit bonus where i have to play 250 raked hands, what is the minimum amount i have to play in limit? is .5/1 limit fine as long as there is a 25 cent rake or do i have to play at least 1/2 limit to clear the FIRST TIME DEPOSIT BONUS? Basically i am saying is the rake requriment different for the first time bonus and the monthly bonus? thanks.
