Absolutely nothing! It's free to use. You can start your own poker league, schedule games, RSVP to events and post classified ads without paying a cent. There is no catch and no place to enter a credit card number like those other kinds of sites we won't mention.
You can help us by supporting our advertisers and checking out their websites and products.
We do offer some additional advanced features as part of our Pro plans. 95% of members will not need or want these, but they offer some cool things, like no advertising.
If you wish to help PokerDIY or want to donate to our upkeep, please check out our Pro plans and become a Player or League Pro.
