please explain.....

some1 please help me out here.

i'm canadian....don't watch cricket...don't care 4 it!! lol. but everyone's talkin' abt this india vs. pak match, so out of loyalty 2 pak, i watched. 2 bad we lost.

anyhow....now please explain.....how many more matches are there, and which ones actually count for something?? for ex: in hockey...we get 4 playoff rounds with 7 games in each round. whoever wins 4/7 wins the series and moves onto the next round. how does it work in cricket for this series, specifically (india/pak)?!

basically, i'm asking......which games r worth watching?! LOL.
