Reddit reviews Puzzlecraft: The Ultimate Guide on How to Construct Every Kind of Puzzle

The best book I know about different kinds of puzzles is Puzzlecraft, by Thomas Snyder and Mike Selinker. I don't remember how international it is, though it certainly covers many of what would be considered "Japanese" logic puzzle types (how Japanese they are is questionable).

There's an 11-step procedure in the book Puzzlecraft: The Ultimate Guide on How to Construct Every Kind of Puzzle, if you have it.

For a book you could look at Puzzlecraft: The Ultimate Guide on How to Construct Every Kind of Puzzle. It was in some Humble Bundle a while ago, but I have only read the first few chapters. Seems to cover many types of puzzles from riddles and crosswords to ... not sure. Not sure if it even has anything about puzzles in digital games, but I imagine the thought processes behind all sorts of puzzles are similar.

EDIT: I only know noticed that one author of that puzzle book, Mike Selinker, is also a published (board) game designer that has worked with some of the largest publishers like WOTC and Avalon Hill on games like Pathfinder Adventure Card Game and Pirates of the Spanish Main. Not sure if that is important or useful information, but hopefully that book also covers some of the types of puzzles that are in games then.

I wonder if his book might be useful in understanding angles he approaches things from?

There are tons of kinds of puzzles. Generally a good way to start is by picking a style you already like.

Sometimes you can find a specific puzzle you like, and tweak the inputs such that the output is foxwoods or whatever.

If you're looking for general puzzle-making advice, this book is a reasonable place to start.

If you want ideas about ideas for puzzle types that you can mold into what you want, then give us something to work with - like a topic or puzzle theme that your friend especially likes, more narrow than 'casinos'.
