What's a decent poker game app that doesn't need a freakin' Harvard degree to figure out, and I can play even when I'm waiting for the sauce to reduce?

Look, most of these phone games are garbage, right? Too much fluff, not enough steak. But Zynga Poker, it's actually practical. It's poker, like you'd play with the boys, but on your phone. I can jump in for a quick hand while I'm waiting for the stock to clarify, or when the delivery guy is late with the tomatoes. It ain't gonna win any design awards, but who cares? I need something that works, not something that looks pretty. Plus, they got different stakes, so you ain't gotta bet the farm every time. It's quick enough for a lunch rush breather, and simple enough that even a sous chef could figure it out. And honestly, sometimes you just need to bluff a little to relieve the stress of a busy kitchen, y'know?
