if you're new to the poker, then I would recommend to you to start reading some good articles on strategy, in top left corner, "Strategy Articles".
If you're not new and just want to start playing and build your bankroll, from 0 to.... then freerolls are good for you to begin with.
You just have to remember, people do not play freerolls like other tourney's, since they don't have nothing to lose.
If you're mediocre player, you can succeed in freerolls,if you have patience, but do not forget, it's a freeroll and almost everyone will call you with almost any 2 cards, so if your AA got cracked by 27o, do not get mad, just bad luck...
you know what I mean
if you already have some $$, I think you have now $.24, depends where are you playing on, on which poker site
, some may have some low lvl buy in, or micro tournament, or even with $.01/.02 games.....
anyway, I wish you the best luck
