ABSTRACT
An underspecified puzzle is one that appears to have multiple solutions. The puzzles here do not even have any instructions, so that part of each puzzle is to figure out what the puzzle is. What is surprising is that, when you’ve found the intended solution, we suspect you’ll know. Some underspecified puzzles are culturally specific, making them difficult or impossible to solve if you’re not familiar with the relevant culture; our apologies. There is one puzzle on each line below.
