The PO freerolls are pretty boss, I'd rather face 50 people for a $30 prizepool than 2500 people for a $50 pool :-)

Carbon has 4 $50 freerolls a day that draw around 2k players, and they also have the "fun steps" S&G where you can get 10 free step 1 coupons each day, and if you make it to a step 3 and win you get $1.

Juicy has some satellite freerolls where the weekly tourny has like a $1k prizepool, but you have to get in like the top 50 or so to get a ticket.

SWC has an hourly freeroll for 50 chips, thats about $6, that tourny gets maybe 100 players, and in odd hours I think I've seen it be 10 handed or less.

Most rooms also have a freeroll for VIP players or depositors etc, you just need to keep an eye out for them.

Seals is nice I get a freeroll every couple days for 500 chips because I played there when bitcoin was mostly worthless and I earned enough player points.
