I honestly don't know, but in my opinion the shorts and Dipper's and Mabel's Guide to Mystery and Nonstop Fun! is canon, I don't know if there are any other books, but the games however, are a different story. I suppose small games like Attic Stuff Golf could be canon but not games like Villains Unite! or other crossover spinoffs.
