You get ten trial sessions (I'm not sure exactly how long a "session" is, but it's enough time to get a feel for most of the puzzles and the gameplay) but thereafter it costs. It's cheaper than City of Heroes, but not by a whole lot -- I think it was around $10.00 if you pay by the month, with significant discounts for quarterly or yearly payments.

You're better off not trying it, trust me. :D
