For the state in this article, seems you can get legal by having the games be more skill based than chance based. So Texas hold-em can be legal. Seems payouts can be cash. Also, it is so rarely prosecuted many were not aware when someone showed up and started prosecuted a few organizations.
CA has charitable gaming, but no cash payouts, as already mentioned.
