If you play the New Player Invitational at Bodog (you have to email email@example.com
to apply for an invitation) and finish in the Top 5 you win great sign up bonuses that will effectively TRIPLE your original deposit AND it is instantly available without any bonus clearing (to play with that is, I doubt you could withdraw it without clearing points).
I finished third and the prize was a $50 instant match + $55 in T$. So when I deposited $50 I instantly had $155 to play with.
The tournament is only open to players that have never deposited at Bodog. It is a free-roll and usually has around 45 entrants. It runs twice a day and you can play as many times as necessary until you place top 5.
