To test the game reply to this post with:
#rootlink [link-to-your-game]
For example, if the user 
#rootlink game1
My bot would look at the page:
https://steemit.com/@dan/game1
for game information.

The game information post should look like this:

Replace the players with the people you want to play with. Rounds are set to a short 22 seconds right now so it will be very hard to play the game. When you miss a round the bot just plays a random card for you
Change the deck to "local" if you want to make your own deck.
Example can be found at

You have to use the #blackcards and #whitecards command to tell the game what's what.
Use one or more underscores '__' in black cards for the blanks.
You'll need at least 50 black cards and 150 white cards.
Max total deck size is 500.
The best database I could find for Cards Against Humanity cards was:
