which sites offer mixed games besides of full tilt and pokerstars?

I play on SWC and Pokio.

SWC (a Bitcoin site) has a bucketload of mixed games. Some of them don't get much action, but every time I play I find 2-7 OFC available to me. There is always 5 card PLO8 action: sometimes there are other games as well, including lowball mix and 11-game. If you want action you can sometimes sit at a table and get it by typing /action in the text box as there is a chat facility that people seem to enjoy using and a message pops up on there.

Pokio is a mobile phone app and I play on here specifically because it offers my favourite game, Pot Limit Sviten Special (Drawmaha). It also offers a variety of OFC variants, PLO, 5 card PLO and of course that 2 card game people seem to like.

If you want to play on Pokio download the app and join my club (100027) - DM me and I will sort you out with some rakeback. Note that Pokio is properly regulated so if you're not in a country where it is legal to play on there, you won't be able to.
