What is the online game site that has the full version games with commercial interruptions?

I’ve been searching for what seems like forever, for a good, addictive online gaming site. I prefer the mindless time management (or diner dash/cake mania types/tycoon) types. A friend told me that she’d found one that had the same trial games I’d found from Bigfish in the full-versions; you just have to deal with a few commercials–does anyone know where I can find this or similar sites?
