I play in loads of freerolls, and tbh it depends on the site.
Absolute and Ultimate, I very rarely cash on, if you wanted a percentage it would be a decimal figure
However I go on T6poker and make the money 60% of the time. Albeit for cents...
Partypoker I average about 25% but I tend to do well in their satellites so get into the money on bigger tournies ie I've got a place in a 10K freeroll at the end of the month and so far theres only 360 qualifiers, so logically there will be about 1000 max taking part. Very good odds
of making some very good money.
Sites like Pokerstars
, they are great fun but with 12000 taking part and no money only seats in bigger tournies, its very rare I get into the money but like Partypoker, its very good money when you get there.
Bodog - Best freerolls on the web, hard to get into the money but lucrative if you do.
Carbon - Joke of a freeroll.
Full Tilt - Easiest to get into the money on but the prizes are crap
Doyles room - A joke of a site. but get into the money and it goes up very quickly. They pay out 600 places and sometimes theres only a couple of thousand entering, so its easy to get into the money
ipoker network - Hard to win. Crap prizes
So in short, it depends on the site. You need to find the ones that suit you best, but heres what to look for
Big starting stacks - Partypoker
Long blinds - Partypoker/Fulltilt/Pokerstars
Smaller fields - T6poker
Big payouts - Doyles Room. Bodog
Loads of donkeys - Doyles Room / Fulltilt / Pokerstars
Big prize fields - Doyles room / Party poker
Pick the best and you cant go wrong.
