Where can i get unlimited games?

i like playing those yahoo games, like burger shop, diner dash, etc (if you dont know what those games are then dont answer the question) anyways. i like to play those types of games but they cost 20 bucks a piece, which adds up. besides that, i complete them pretty quickly. i just want to know if anyone knows a site that i can like pay lets say 50 bucks a month to play them unlimited. not just one, but many games, please help. I'm looking for games similar to my examples, not "warcraft" or "super mario brothers"..........Where can i get unlimited games?
What about gamefly?
