Free play money with 1000 recharge every hour.
No pressure to spend money and you can enter paly money tourments.
I been there for few years now.
but if you drop some coin into them you do seem to get unusual cards dealt.
But by same token micro plays are fun and small budget, i can play with micro for months $10 is all ya need.
But what id do use it for is honing my skills for playing real money at the casinos here in africa.
I know i gonna loose in poker stars, it is the way it is. but it gives you great training.
then when you play the real thing in the casino, and you play tight, i never seem to loose.
remember play small, walk away, stick to a budget you can afford.
cheers
