I haven't connected it to Rigly, I don't think that's the idea, they only act as an auction house and deliver the hashrate to the same pools you can connect your mining rig.

My Gamma is connected to public-pool.io mining solo, so I'm not being rewarded unless I find a block.

You might wanna take a look at this repo, I've collected as much about the Gamma as I could, if you have a contribution that's welsome.
