Donkey Puzzle Tree is an intermittent puzzle outlet for Max Carpenter. Max has had his puzzles published elsewhere—you may have seen them. If you would like to publish his puzzles, or order a custom puzzle, you can reach out to him (see “Contact” for ∑-m@il, or click ahead if you prefer the Vermicious Knid that is Twitter).

The name is an homage to the late crossword setter John Graham.
