I have been playing the 1.10 games on Carbon that give 8-12 $33.00 tickets GTD, and usually have enough rebuy $$ to add more tickets or some cash awards as well!
The crazy thing is, I have not only gotten the ticket, but made a few more $$ than what I spent to get it. So far, I have only bought into each one I played once and then spent another buck to add on for 20k after the first break. Incredibly, many players easily spend $10-15.00 in rebuys each game and by the second or third day you see them you have to wonder why not just spend the $33.00? I mean, rebuy for more than you can win? It's crazy!
These multi ticket GTD games are usually 1500-3000 starting stack and 5 minute levels. If you play it right, you can end up making a huge stack; many players have incredibly obvious betting tells
and this can allow you to get them all in. Once you get around 12-20k in chips you can start ripping the 3k stacks off left and right as they have to shove. By the time late entry is almost over, blinds are at 1400 or so and they STILL buy in with only 2 BB's and insta-add in for another 2bb's. At that point, they are shoving with any two cards. And they do not stop if they work up to 20-30k, still shoving weak. If you limp big hands you can catch them doing this and end up with a huge stack!
Best of all is that they have some pretty decent games for the 33.00 ticket you win! Just keep in mind (I could be wrong, they might have changed it) but you can only buy in for a ticket; as far as I know, you cannot use a ticket to re-buy into the same event. You should be able to for a re-entry, however.
