I only have one Category Train game for sale at this time, in July 2013, but all of the games that use categories could use these rules. No additional parts needed, just the key and the cards with these rules.
Here are the rules you can use to create your own printable game.
Just like the other games, I suggest creating your key first, then making the game cards using it as a reference.
The MatchIt Card Game, Stephanie's Spinner Card Game, and this Category Train Card Game can use the same game cards.
Phonics rules work well with categories, but I also have a Vertebrates MatchIt Card Game, a Color and Shape early learning game, a Five Senses Card Game and a Parts of Speech Card Game, that use categories of information.
