On the freerolls, are chips bought to be used or it is provided on the platform?
I use PokerNow more often, but the two platforms are way different from each other, that's why my questions are coming this way.
Freerolls are free, you don't need to buy chips or deposit to play them.
They are scheduled every 2 hours and alternate between NL Holdem and another random game, which could be PLO, Drawmaha, 27TD, basically any of the variants on the site.
Starting stacks in the freerolls vary from 800 to I think 1200 chips depending on the variant. Prize pools are usually 10 or 20 chips. (10 or 20 uBTC).
