How do i find out house edge

[favour]

I was checking for house edge on blackjack games against Wizard of odds
http://wizardofodds.com/realtime states house edge is .49
http://wizardofodds.com/advertisers states in add edge is .2
the site is easier to play than some others especially with surrender but wich is correct?

just looking for a place to play for fun

There is an odds calculator that seems pretty accurate(I don't remember the exact location, but it's there and easy to use). But a sim will tell you the exact odds for the rules you are playing.
